I removed all three servos, disassembled them, cleaned them with solvent and contact cleaner, reassembled and reinstalled them. That was two years ago and they have preformed great with no issues. Took about 3-4 hours. A best practice prior to doing any of this is to get pictures of everything before you start and during the procedure. Always good to document everything prior, during, and post.

Thanks for the direction. I will get that done soon.

My 2001 Rx has 190,000 miles on it. I have owned it since 38,000 miles and have done a pretty good job of completing preventative maintenance. One area I haven't yet done is the transmission. Heard many things stating if you do one for the dirt time with this many miles it stands a good chance of failing soon after. Is this correct?

Last night I pulled the belts and cleaned all the pulleys. Lubricated the alternator shaft, reinstalled belts, then adjusted the tension. Checked pully alignments for paralellism. Started engine and the noise is still there. What else should I check? Could it be the timing belt? It has about 85000 miles on this belt.

I have a 2001 rx with 187000 miles. It came with Bridgestones HL and they got changed out around 40thousand miles, no performance issues only wear. Replaced with a new set and got the same life. Went with a third set and all heck broke loose! Wore horrible! Cupped so bad Bridgestone replaced them after 4500 miles!The new set wore better, 35000 miles, but not as good as the first two. Went to a Firestone dealer who looked at the tires, found issues and replaced them with Destinations. Great tire, ran for 60000 and replaced them with the same. They do very good in weather, snow or rain. Not much noise and ride pretty smooth.

I have a 2001 RX300 with belt noise (sounds like a bad belt), alternator, smog pump(?). Repalced the belts with new NAPA belts and still have noise. This noise is most notable when engine is about 2000rpm.

thanks for the directions. It wasn't the gas cap it was the connection the cap is captured in. The seal edge on the connection had some random deposits of solid residue. I cleaned this off with a light scotch-brite (the white one) and coated it with silicone vacuum grease. Reinstalled the cap and the negative lead to the battery and the warning lights haven't illuminated since.

I have a 2001 RX300. The check engine light and VSC lights are now illuminated on the dash. The codes pulled are PO441, PO446, and PO440. It is not the gas cap. Where should I begin?
