Have a 2010 RX350 and was told today at inspection that the rear shocks are leaking. I see there was a TSB on these but we are over the 4 year warranty period.

So I start looking online for parts and there can be either a TMK or a TMMC Rx as far as the part numbers for the rear shocks. Just what does this mean and how do I find out which one is mine.

Also, changed many a shock years ago and wondered if these are pretty the same as much a bolt off and bolt on replacement. Thanks for any info.

These are merely references to the plant of manufacture for your RX350 are are not necessary. Your vehicle's VIN gives you all you need. If it starts with a "J" it was built in Japan. If the VIN starts with a "2" it was built in Canada.

TMMC = Toyota Motor Manufacturing Canada
TMK = Toyota Motor Kyushu

Why don't you stop by your Lexus dealership and bring over the TSB with you. And call the corporate at 800-25LEXUS. They might go out of their way and cover the work for you.

My IS300 had developed a slight peeling at the edges of the HVAC panel at the 6th year of ownership. There was a TSB for it, but my VIN was not on the list. After 3 trips to the dealer and a couple calls to the corporate, they replaced the panel at no charge.

A great customer service goes a long way, so I few years later, I bought yet another Lexus.

Thanks guys for the info. Is it better to stick Ruth OEM shocks or are ones from online auto stores or local auto parts stores ok ? Tks.

stick with original shocks, get it from sewell lexus for $63 each,install it yourself if you can.

It doesn't look like there are a lot of choices for aftermarket. You're better off sticking with OEMs.

There are no aftermarket shocks or struts. The rear ones are shocks and a simple bolt on. I will try to find time to look up the bolt torque in the next few days.

Does anyone know the lower bolt size on rear shock 2012 RX 350? I can't get the old one out, so I have to cut it and would like to have new bolt ready.

Just put KYB shocks on rear of mine . It rides a lot better than OEM .

Just wondering, is your car an AWD? Thanks for sharing!

Are the KYB shocks softer or firmer? Thanks!

Bailey12: First try spraying the old bolt with PB Blaster several times over the next couple days. Spray both sides and give it time to soak in. Also, make sure you have a modern socket that grabs the flats and not an old one that grabs the corners and rounds them off. These bolts are only about 70 or 80 pounds torque. Finally, if none of this works, pull the bolt from the other side to determine what size the frozen one is.

I heard the KYBs were softer.

Mine is awd . 6 months ago I put on OEM shocks on the rear . It rode pretty stiff to me .I didn't like the ride .
I then decided to try KYB shocks . I think they were about 73.00 apiece on line . The ride quality definitely improved . It is softer than OEM .
I don't feel every little road imperfection like before . It just takes the harshness out of the ride . It stills handles fine .It buy no means is to soft . I plan on putting KYB on the front soon also . Mine has 100000 miles on it now . I also set tire pressure at the pressure on the door jamb .I think its 31 Psi which also helps the ride quality .

As far as a bolt being stuck .Put a little pressure under the lower control arm [jack] to take the weight off the shock . That helped me get the bolts out .

A decades old solution for stuck parts which is vastly better than PB Blaster is a mixture of acetone with ATF... equal parts of each. Shake well and dose the rusted bolts. Fast and deep penetration. Sworn by solution to many mechanics over the years, and very cheap to make. One additional side benefit is that it doesn't smell nearly as bad as PB Blaster!
