One of the recurring service item is

Inspect (re-torque?) chassis nuts and bolts.

Is there a picture for their location and specification? Some one with the service manual be kind enough to post.

I have 450RX and I bet the chassis nuts/bolts would not be different from 350.

[PS: Other than what I seek, members are encouraged to pile on and list any spec that is related to recommend service spec. Lets hope that this thread does not become a discussion on service and stays as a reference page for DIYers]

I recall the RX350 AWD calls for torquing the drive shaft bolts/nuts to 80 foot pounds every 30,000 miles or so. I did it once and they were all tight. At 70,000 I will check them again this Summer. I do not think the hybrid has a drive shaft.
I suppose they want the control arms, trailing arms and shock & strut mount bolts checked.

Many years ago a friend's Buick that was not old had a rear shock absorber lower bolt get loose and fall out. But that was a US car from the 1980s....

^^ The only U.S. vehicles from the 1980s that I was ever willing to acquire were a 1985 Jeep Cherokee, a 1985 Chevy S-10 Blazer, and a 1988 Jeep Cherokee. All three turned out to be quite good SUVs for us.

Hybrid does not have driveshaft, Salim jan. Otherwise, get her up on a lift or stands and crawl under and basically get socket/wrench on all nuts you can find and torque them. Control arms, struts, engine mounts, sway bar, sway bar links, connecting links in the back. They are likely OK but my 2015 NX developed "self loosening" suspension bolts that dealer re torqued - at just over 30K miles. Yep. Better safe.

Thank you for the term of endearment, but I need to know exactly which nut/bolt and to what value. Please check the warranty/service manual short book and there is a check box for 'chassis' and I would like to put a check mark there.

My quest is incomplete.

If any one does their service themselves ... please enter part number, volume used. torque-specs in this thread and let it be a good resource for DIYers. [Please no detailed discussions in this thread. Once it takes off, I might go back and clean it out. Fair warning .. the bunch of typing any one does in this thread may be deleted.]

BUMP....2 months later. this is EXACTLY the question I've had for some time. What the heck is this requirement specifically? There has to be come specific directions on this because it seems to me to be a safety issue. If you have a loose bolt on a suspension or chassis bolt that fails, you can lose control of the vehicle! Anyone have access to the lexus service manual to be able to look up the dealer directions on this? TIA
