yup totally agree, the axle shafts with new boots in under $100 apiece, just a matter of labor.....

First the knock sensor will cause the indicated transmission issue. The first thing to do is find a independent that handles Toyota products and get a reasonable price for replacing the knock sensor, which by the way is buried under the intake manifold so yes is is labor intensive. Highly suggest replacing the wiring loom going to the sensors also, but at least inspect them for any insulation missing.

You would think those items would be spelled out in the service write up sheet so that no mistakes would be made while servicing. Maybe they need a bar code system for items for service. Which dealer was it?

That one is easier to replace

Thank you for your feedback....I too agree sorry about no responses....Welcome aboard. Hope in the future you find helpful info on this site.

Here is one thread discussing the topic about the servo http://www.clublexus.com/forums/rx-first-generation/293932-rx300-fan-noise-blend-door-motor.html

The bearing could be bad, but I would not replace all bearings as preventative. Cost at the dealership could be quite expensive. The front bearing itself is about $60 but the labor involved is what will cost you. The front hub has to be removed and the bearing pressed out. If the same bearing failed than they may have improperly pressed it in which could cause damage to the bearing. The bearing is a very large sealed roller bearing. You might find cheaper prices at Toyota or an independent garage that handles Toyota products. Another cause of vibration if it is AWD (all wheel drive) is the carrier bearings in the drive shaft going to the rear wheels... If you have front wheel drive you would not have this bearing. Oh man misread, if it is the rear bearing than the whole hub can be replaced. After market Timken bearing/hub can be had for as little as $160 or less. Again a independent might be cheapest for this maintenance.

Actually the RX400h has a timing belt and was last produced in 2008...Yes the 3.5 liter engine is a timing chain. As for the reference to interference engine in the RX330 it is definetly interference and the Lexus mechanics quote saying it is not is not true. With the introduction of VVTi technology on the Toyota engine from 1999 thru 2008 the engines are all interference. There is no such thing as lifetime on anything. Shocks do wear, timing chains do stretch, and transmission fluids do become contaminated. Life time is a sales pitch to say no maintenance cost. Buyer beware.

Might be the IACV (Idle Air Control Valve) There is a way to clean this valve and rectify your problem. Do a IACV search in the RX300 Forums....there is a great thread to cleaning this valve. edit: here it is http://us.lexusownersclub.com/forums/topic/30723-step-by-step-instructions-for-iacvidle-air-control-valveiscthrottl/

Please note a little dielectric grease on the coil before putting on the plug may also help in any arcing issues do to corrosion and moisture.

usually just four....

When In P (park) there is a gear backlash (some movement) however it should stop the movement after that. As for your parking brake, hopefully it just needs adjustment....

Learned the hard way on British Cars....(wrenching constantly and racing the Triumph TR-250, known as a TR-5 in Europe) Between Lucas ignitions, Smiths instruments and Laycock de normanville transmission you were always busy. But what a manly car.....15 inch wheels with IRS rear suspension and air horns and driving lights and you were good to go through the Spanish countryside. Oh those were the days...Don't miss the brakes which constantly leaked and was a challenge to stop sometimes. Overheating was another challenge. And Goodness I don't mess ignition points. The Jaguar was like putting your money on the edge of the Grand Canyon and kicking it in. But boy what a sweet handling machine. Fastest I have ever gone was 149 mph and that car was perfectly stable....

Funny most drain plugs are around 25 to 29 foot pounds, just a good ball park range...

Read this thread and see my samples of fluid at the change interval of 89k.....The front transaxle was quite dirty brown....I would highly suggest changing. The manual is very vague about change interval but I believe it is around 90k. http://us.lexusownersclub.com/forums/topic/68738-cvt-rear-differential-fluid/page-2#entry467716

Complete rip off....The rear is just like an old fashioned differential drain and fill only....1 quart of fluid takes about 10 minutes... So $10 bucks in fluid and one hour of labor????? As for the front you get out over 80% of the fluid with a drain and fill. take 4 quarts of WS fluid and the huge labor of removing a drain plug and refill plug...again just like the cars of old with the old style differential. Wow real rocket Science....Total cost should be 1 hour and $60 bucks worth of fluid....They are totally ripping you off....

Oh yea. I think it is better.

PB blaster is a anti lock lubricant that frees corroaded parts......

PB blaster and soak, then try.....

Here is part on Ebay: http://www.ebay.com/itm/Lexus-RX-330-04-06-Multiplex-Network-Door-Computer-Unit-Module-89222-0E012-A353-/331027445556?pt=Motors_Car_Truck_Parts_Accessories&hash=item4d12c5f734&vxp=mtr Probably not that difficult to replace (under 1 hour) Heck fix it and keep car......

I actually ordered the rear magnetic plug and installed on the front tranny...

I would think the most damage would be to clutch plates in the transmission. overfill of engine would possible cause oil being blown into the intake manifold. Hopefully all fluids are now at proper levels...good luck

http://www.clublexus.com/forums/2889437-post3.html enjoy the pictures....check wire connections carefully

Thanks for feed back....I would assume (yea I know bad thinking) that even us second owners would be notified since I am registered on my Lexus site.

If you have an ohm meter I would suggest also seeing if there is a short on that sensor or the harness. Check the wiring going to sensor for abraided insulation. Also the plug itself could be corroaded causing such behavior.
