"Even though it was my fault...." NOT...!! For some reason the dealer was not exactly truthful with you. The LS460 has a 10 amp fuse for serving both backup lights. Two fifty watt halogen backup lamps/bulbs would draw ~9 amps and so in the normal case the 10 amp fuse would suffice. And quite obviously it would quickly blow, open the backup circuit, at even the slightest overcurrent problem. So your "main fuse" blew for an entirely different reason which is probably why the dealer didn't charge you for the service. Were it me I would go back and find out exactly what they found wrong that caused the main fuse to blow.

Well.......??

Normal, SOP. With wheelspin/slip that results from too much engine torque for roadbed conditions the brakes will be applied to the slipping wheel(s) and the engine will be dethrottled to prevent brake overheating and rotor warping.

First, if you put in max hot all the sensors are bypassed and the reheat/remix door is "blindly" driven to the full remix, max heat position. The opposite is true in max cool position. If that doesn't work then I would disconnect the battery for 10-15 minutes. When you reconnect the battery you should hear a bit of "buzzing" and "wherring" behind the dash as the HVAC ECU recalibrates all of the servomotors. The see if it work properly.

Maybe as a "damper" for intake resonance...?? Loose fitting...??

Within our family, company and close relatives we have a 91 LS, 2 92 LSes, and a 95 LS, all with well over 100,000 miles, 210,000 for the 95. At least two of these have the Nakimichis but NONE have had speakers fail. Of course maybe none of US are likely to try to hear "low" musical sequences by turning the volume up so the "low" tunes/sequences are above the ~70 Db ambient noise level at speed, putting the "high" tunes/sequence at 180 Db.

Depends on where you take it,.. a good , friendly, indie can replace your motor and trans mounts quickly, and for under 200$ if they are nice, a bit more if they mark up labor and parts more -- Not sure where lexus would go with this. Tires,.. obviously non labor intensive, can be done in minutes literally.. likely a 15-1hour wait.. unless you just get it all done at once (best option). Now the Constant Velocity joint (Lexus uses these? Fantastic.. I thought it was just a U joint for the RWD.. but again I'm not well versed on these cars yet) -- Anyhow.. this joint is expensive (to me).. new. From other vehicles I remember they run about $500.00 new from a dealer. Though, getting a rebuilt unit can cost considerably less, and I wouldn't dissaprove of it. If you have the money, go with the cheapest 'new' joint you can -- But if your running tight on money, a rebuilt unit (imho) will do just fine. The labor, as you asked, is not intensive (relatively). Think of a bad CV joint as a popping sound if the outer portion is bad, and a pluuuning sound if the inner core is bad. They last anywhere from 10-15yrs before you really need to get them changed out. First, I have experienced a stuck caliper, right front, on a '91 LS400 and it was due to the little rubber boot covering the top "slide pin" having failed, completely disappeared. As a result the slide pin lost all of the lubricating grease and the caliper became stuck in place. Lexus simply replaced the slide pin and boot, minimum cost. It is my understanding that the vibration has nothing to do with braking so for me that would rule out warped or uneven thickness rotors. And since CV joints are tradionally more robust, reliable, vs u-joints I would check/replace the driveshaft u-joints FIRST, before doing anything else. If replacing the u-jopint doesn't resolve the problem then I would look next at the CV joints in the rear halfshafts. Motor and transmission mounts seem to me to be a "wild goose chase". Replacing the (old, worn, "flaccid") mounts would undoubtedly somewhat subdue a vibration caused by driveline u-joints but eventually you would find your driveshaft lying back down the road apiece.

I first noticed this on my '01 AWD RX300, at fairly low miles the glass encapsulation for the high beam bulbs was internally "sooted" over and there was a bubble in the glass above the filament. I had upgraded to PIAA higher wattage bulbs so I guess I wrote it off to that, PIAAs, although I had found documents on the internet in operating halogen bulbs as DRLs at low voltage could result in those effects. Yesterday I had to replace a burned out low beam in our 95 LS400 (210,000 miles). In the process of replacing the high/low beam H4 bulb I noticed that the second high beam bulb (60W HB3/9005), the one used for DRL, looked odd, bluish. When I removed it it was as I described above for the RX300. So those of you with high beams as DRLs might want to check the condition of the bulb.

I suspect if you check more closely you will note that you do have bi-xenons and the HB halogen is there for "fill" and for DRL. The projector HID has a shading apperture for low beam which is moved out of the way via an eelctric solenoid in high beam mode. The lead car on the left has the same bi-xenon arrangement.

Your dealer is NOT pulling heads just to snoop around..!! The V6 in the 2001 Model is subject to the engine sludge issue and you can bet that the factory is paying them to overhaul an engine that has/is exhibiting oil sludging.

You can substitute a 5 cent 1/4 watt resistor.... Check the shop/repair manual for the range of resistance for the leveling sensor and pick something in the middle to start. Then adjust the resistance empirically, trial and error, until the auto-leveling sequence settles at about the right, desired, height.

Two SEPARATE problems... 1. The front caliper is stuck resulting in overheating. 2. A u-joint in the rear driveshaft or a CV joint in one of the "half-shafts" at the rear is failing resulting in the vibration.

From the 2009 RX350 shop/repair manual: Does "2. Traction Control Operation" make it sound as if a VC is in use..?? Even if it were actually installed..?? System Outline 1.ABS Operation If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all four of the wheels automatically to prevent the wheels from locking and ensure the directional and steering stability of the vehicle. If the brake pedal is depressed suddenly, the skid control ECU controls the solenoids in the actuators using the signals from the sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinders. Additionally, if the skid control ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators to increase the braking pressure. 2.Traction Control Operation The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, and any wheel slipping which occurs at take off or during acceleration of the vehicle, to optimize the driving power and vehicle stability according to the road conditions. 3.VSC Operation Unexpected road conditions, vehicle speed, emergency situations, and other external factors may cause large a under­ or over­steer of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to reduce the under­ or over­steer. Reducing excessive over­steer : If the VSC system determines that the over­steer is excessive, it activates the brakes on the outer turning wheels according to the degree of the over­steer to produce moment toward the outside of the vehicle and reduce the over­steer. Reducing large under­steering : If the VSC system determines that the under­steer is excessive, it controls the engine power and activates the rear wheel brakes to reduce the under­steer. 4.Mutual System Control To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are collectively controlled while the VSC system is being operated. Engine fuel injection control The engine power is prevented from interfering with the VSC brake control by adjusting the fuel injection opening and reducing the engine output. Engine control and electronically controlled transmission control Strong engine braking force is prevented from interfering with the braking force control of the VSC system by turning off the accelerator and reducing changes in the driving torque at shift­down. VSC system operation indication The slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whenever the VSC system is operating. 5.Fail Safe Function If an error occurs in the skid control ECU, sensor signals, and/or actuators, the skid control ECU inhibits the brake actuator control and inputs an error signal to the engine control module. According to the error signal, the brake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open requests from the VSC system. As a result, the vehicle continues to function but without the ABS, TRAC, and VSC systems. ----- Original Message ----- From: Lexus Customer Satisfaction To: Ceo Sent: Monday, February 04, 2008 3:48 PM Subject: RX350 Viscous Clutch [incident: 080131-000328] Recently you submitted a question to the Lexus Customer Satisfaction Department.

RX350 Viscous Clutch Stefanie, The 2007 RX350 Lexus shop/repair manual at techinfo.toyota.com does indeed state that the RX350 series uses the MF2AV transfer unit vs the MF2A used in the RX330. According to the accompaning component layout/diagram the MF2AV has a Viscous Clutch. But in searching for "viscous" or "MF2AV" in the 2007 and 2008 Lexus shop/repair manuals I get a return of "not found". On the other hand if I search for MF2A both RX350 repair manual sets, '07 and '08, indicate the use of the MF2A transfer which does not have a viscous clutch. According to New Car Features for the 2004 RX330 it is not VSC, but TRAC, Traction Control, that supplants the need for a viscous clutch. The wording for TRAC functionality in the 2008 RX350 is EXACTLY the same as that for the 2004 RX330. Assuming you are correct and the RX350 actually has/uses a VC, whose responsibility is it now to notify the personel in charge of publishing the RX350 shop/repair manuals that a MASSIVE revision must be made.

I was wrong again, retractor back together and still will not retract without help, "push". I guess the clocksprings are shot. So, I'm buying new ones.

Well, Debbie Downer, I wanted indash navigation, bluetooth, ipod, and satellite radio. Doing the soundproofing wouldn't help me with that would it? Who says I won't do that stuff too. All I can tell you is that I am very very pleased with this upgrade. And I know others that would like to do the same to their RX but they didn't think it was possible so I wanted to make sure the people on here knew. Oh, well, now I understand. As "Debbie Downer" I see absolutely no need for bluetooth, ipod, nor satelite radio. Insofar as GPS/Nav is concerned I find that a built-in is a waste. I'd much rather have a portable (which I do) that I can move from car to car, or even car to Cessna.

You can confirm a warped disc by applying the brakes.......you will feel a pulsation at lower speeds which tranlsates to a vibration at higher speeds because the frequency of the pulsation increases with speed. The more pressure you apply - the more pronounced the pulsation/vibratiion. Indicates a seizing caliper. Would have that serviced without delay. Don't compromise on your braking. my left disc gets very hot and as a result the caliper gets hot as well. while im driving bellow 70-80klm/h there is no vibrations almost at all, as well not on the steering wheel, and if i didnt drive any faster then 70-80klm/h, then i wouldnt know there is any problem.. maybe it could be the caliper??? "maybe it could be the caliper???" No, much more likely you have two separate problems, a stuck caliper and a bad u-joint. Or maybe a rear drive shaft CV joint is failing.

There are 6 dual filament (type 7443 for a 95), 18 watt stop & 4 watt tail, in an LS400. It would take 30 watts, probably as 3 10 watt resistors to equal the current flow/draw of the taillight filaments. The stop light filament is 18 watts, meaning a total of 108 watts of resistance to substitute for the actual stop light filaments. Typically LED lamps draw only about 10% of the current flow of their incandescent counterparts.

$2500.00...?? To justify that you must spent one helluva lot of time listening to that system just setting inside your RX closed up inside the garage with the engine off. Otherwise the typical 70Db road noise, "white" noise, "over-shadows" the lower level "sounds" so much that you must have the volume up in the painful to the ears range for the "high" sequences. The best investment to improve the automotive audio "listening" experience is via more sound proofing, noise reduction. Undercoating the wheelwell liners, nice quiet higher profile 16-17" summer tires, fiberglass insulation in the doors, coat of silicone lub on the rubber window seals, etc, and maybe even an "anti-noise, noise canceling, module under the driver's seat. And it wouldn't hurt to add some DSP, Digital Signal Processing, to automatically bring the "low" musical sequences up to, or even above, the level of the cabin ambient NOISE. Having done all of that you'd likely be pleasantly surprised at just how well the factory system sounds.

BRIGHT sunlight or flashlight.... What is your reason for testing...??

"1/2 second interval"... That would seemingly indicate a rotational function that "wonders" in and out of synchronization... That might result from slightly different tire circumference L/R. Front halfshaft CV's for FWD. Rear drive axle CV's for RWD. Or even L/R or R/L tires. Does the vibration lessen with slight left or right turn....long sweeping curve..??

Since someone managed to back into our '95 LS (Silver) and break the passenger side rear tailight I purchased the red/clear full set on Ebay. Cheaper than just buying the one at Lexus. And yes, you can add resistors in parallel with the LED lamps. For the tailights, 6 of them at 5 watts each it will take a 30 watt resistor to draw the correct current and not trip the failure sensor. The stop lights are a bit more of a problem, 18 watts X 6, but they the duty cycle is relatively short so the resistor(s) would likely never get all that hot. But all in all being the perfectionist that I am I would much rather change out the current, AMPS, sensing resistors in the lamp failure detection module and even the one in the flasher relay if it should come to that.
