Steering wheel shakes while braking
2010 RX350 ...Any ideas of why my steering wheel shakes when I’m braking at relatively high speeds, like when I’m getting off an exit ramp from the interstate. Just had my car inspected and it wasn’t the rotors nor pads. Car passed with flying colors.
Thx

warped rotors...
how did they inspect the rotors? thickness checks isn't a proper check...
if they are still thick enough, take off the front rotors and take them to a machine shop to turn...

Thanks for the info folks. The Toyota dealership when I had it inspected told me it passed and that the rotors were “fine”. . They babbled on about checking the wheel balance. I really don’t think they looked at them. Lexus dealership is 60 miles away. I’m bringing it there for 2 recalls in 2 weeks. I’ll have them look at it. Hell.. I was as surprised as the rest, I expected that they would tell me the rotors are shot and want to charge me an arm and a leg. I’m a DIY guy but with this stuff, I know nothing.

Wheel balance or a bad tire can cause a shake, but it usually is not dependent on braking.
Most of the time I have seen warped rotors, it is because someone over torqued, or has uneven torque, on the lug nuts. Of course this is usually detected by doing a run-out test, and requires replacement or resurfacing of the rotors, but take a look at post #8 in this thread:
https://www.clublexus.com/forums/rx-...p-warping.html
It appears that the owner had a warp that was corrected by correcting the torque on the lug nuts, and not have permanent damage to the rotor (something I have never seen in 30 some years of wrenching.)
If this is the case, I would guess the run-out test would have proven to be inconclusive as a test for warping in his case.
If you have a torque wrench and the time, I would be curious to know if you get the same results as tman9999 when removing the lug nuts, basically torque values all over the place, and if installing them to the correct spec, and correct order/pattern, fixes your problem. If for no other reason, I would really like a second data point for this being reproducible and a pattern

thank you tus.. I do not have a torque wrench but do know someone who does and can check. Much appreciated. I’ll let you know.

Also, to the OP Go Hoos! hope they don't go out in the first round this year. He or she should know what I am talking about.

I read that post and there is no way you can correct a "warp" by re torquing the lug nuts. What is done is done. Also, all the evidence is that rotors do not warp. It is an uneven distribution of pad material that contributes to the pulsating we call warp. The individual that re did the lug nuts and magically corrected the problem is delusional. Checking the torque at this point will not correct the problem. My guess is that the inspection did not include a test drive that would have discovered the problem. Get the rotors turned or replaced and the problem will go away.

thank you.. I’ll make sure to do that. Is it usually all the rotors or just the front that’s contributing to the pulsating? And.. yes, I know exactly what you’re talking about.. glad you caught the ”Hoo” reference. Duke coming up, that’s going to be a battle. UMBC..ughhhh
Duke vs UVA should be a good game.
