ricco750

I would highly recommend an RX...a 330 or newer 350. You'll note I have a 99 RX300, which I have owned for 10 years, and have made significant improvements on over those years, but I would not recommend you buy one over 10 years old. The RXs are easy to get in and out of, and have luxury class appointments throughout. I'm 72, and don't like vehicles that I have to "fall in" for entry and "climb out" for exit. Regarding hybrids, I stay away from those. The technology is still evolving, and is very expensive to fix when it goes awry. And you don't need to always go to a Lexus Dealership for service...unless you always want to pay more than you should. A good independent shop is better for all but the most major repairs, such as engine and transmission, and even then there are Independents who do excellent work...you just have to find them. Stay away from the major chain places like Firestone, PepBoys, Jiffy Lube, etc...find a place that is family oriented, and that know you and your car.

I went with the Lexus OEM springs and KYB struts. I also replaced Control Arms, Inner and Outer Tie Rod Ends, Ball Joints, and Stabilizer Sway Bar End Links. Pretty much the entire suspension. I could not be more pleased with the change in handling and ride. Corners much better, very little dive in a tight fast turn, and the ride is just a tad bit firmer. The "worth" is a judgment call...I had a new short block in 2009, and the interior and exterior look like a car that is just a few years old. Compared to the cost of a new or newer RX, I think my money was well spent. Plus, my RX also serves as a "hobby" for me, and the little stuff that comes up is interesting to fix. For instance...and I had been waiting for this to happen...I looked out in the garage yesterday to see my radio antenna in the "up" position, signaling that a new antenna mast is needed. Good luck with your endeavor.

UGO, I noticed you have not been overwhelmed with replies and suggestions. I have had the same problem with my '99 RX and my "02 Toyota HL V6. Yes, the IAC cleaning helped a little, but then the problem returned. The only thing that really "fixed" it was to replace...as in new...IAC valves. I used the ones made by Intermotor, and they worked fine. Now, if you have already fixed the problem by fixing the "fuel pump resistor", please let us know. Good luck.

Well, I ended up having to buy them from Lexus, to the tune of about $700 before tax. Now I'm just waiting for the install appointment at my favorite shop for a complete replacement of my steering and suspension components. Between Lexus and RockAuto, I've got about two grand in parts on my living room floor.

I'm trying to find some OE springs for my '99 RX AWD, but other than getting them from Lexus at a hefty price, I can't find anything on the web. Not even MOOG makes them. I found the H&R lowering springs, but don't really want the car any lower, I read somewhere that RAV4 springs were identical, but don't know the year, or if that's true. I'm doing a major R/R on my suspension and steering at a good shop, and my mechanic suggested new springs as well. The springs will be hosting new KYB's. I have also read that some people think that if the car has not towed heavy loads, the springs should be OK. Does anyone have any information about the whereabouts of OE springs?

The first place I would start is by cleaning the IAC valve.

I found this question interesting, so went out to the garage and popped the hood on my '99 RX, opened the fuse box on the right...could not find any relay that specifically said "AC relay". So I looked at the wiring schematic in my Haynes manual for the AC system, and it's pretty complicated, and of course even involves the ECU as part of the "team". Right off hand, I would think that if you had a "bad relay", that pushing and holding the "AC button" would not turn on the AC. I had a problem like this on my wife's '02 Toyota HL, and the fix was a new HVAC Control Unit to the tune of $687 back in '07. Hope this helps.

Maybe you have fixed this by now, but it sounds like a bad TPS http://www.buzzle.com/articles/symptoms-of-a-bad-throttle-position-sensor.html

Have you considered sheepskin seat and armrest covers ? I have them on my '99RX just for the comfort...there was no problem with the original seat and armrest covers, but I got spoiled by sheepskin covers over 20 years ago, and can't go without them.

First, you need to isolate the problem. If it is the blower, that can be determined by going through all the fan speeds while the car is idling. If the noise changes, the problem is most likely the blower...and you cannot "get to the bearings", as they are sealed, and a blower replacement would be necessary. It also could be some debris in the fan cage itself. But if the blower and fan cage are not the problem, then it's most likely the servos that operate the blend doors for the climate control system. They are not cheap to replace, but are relatively easy to remove and rebuild, and there are threads on the forum to help with this. I had this problem with my "99 RX...the noise was a clicking and clacking that sounded like the CD changer was searching for a disc, but it turned out to be the servos. An inexpensive mechanic's stethescope will help with the diagnosis.

This has been a notorious issue on both Lexus sites I visit. The consensus of the majority of the members is to NEVER do a flush, but do a simple drain and refill. If this had happened to me, I would hold the dealer culpable and expect a financial partnership in the repair/replacement of my transaxle.

Unless you rebuild engines, I doubt it is something you can repair. And that "knocking" noise is probably a rod knock. You should definitely not drive it, and it should be towed to a shop. My "99 RX threw a rod though the oil pan at 109,000 miles. It was my mother-in-law's car at the time, had been cared for very well, and was being driven at a highway speed when it happened. I was not driving the car at the time, so I don't know if the oil pressure light was on...it was being driven by my brother-in-law, who tends to ignore stuff like CEL's and such. Anyway, I bought the car after that, and Lexus put in a new short block, and gave me a 25% reduction in the parts. Still, the total bill was about 7 grand. The crankshaft bearings on the old block were blue from friction heat, so there had to be an oil starvation problem, but the original cause, be it low oil level or a bad oil pump, or a restriction somewhere...was never determined. Anyway, I hope you have a good relationship with your wallet, because you are probably about to ask for a favor! Good Luck.

The poly bushings are favorites of the off-road guys. I definitely would not mix poly and rubber, and if I were (subjunctive) to replace the bushings on my RX, I would go with rubber.

I'm assuming you know that the poly bushings make the ride stiffer, not as comfy?
