Great suggestion. None of the 4 rims are bent. The front tires went to the back. The rear tires came to the front and two new tires were balanced and mounted today, but the steering wheel shaking issue persists. I should add that this issue is isolated to the front right because I can feel the steering wheel shaking and a rattling noise is heard inside the cabin. I can see the glove compartment rattle, too. I’m wondering if it’s the CV axle, control arm, or other suspension component. Any thoughts?

Bent CV axle? I've experienced vibration from bad U-joints and bent driveshafts on rear-drive cars, but front driveshafts are a different animal. Probably still worth checking. That car has low mileage but is old enough that examining the suspension bushings would probably be a good idea if that has not already been done. Are there any other clues, like the vibration changing with acceleration or deceleration, or changing when moving the steering wheel?

I checked the CV axle and it doesn’t appear bent. I took a look at all of the front right suspension components and steering components, but no luck. Nothing is leaking or appears broken. I mostly feel like the steering wheel vibration at highway speeds. I can feel it starting at 55 MPH and it gets worse the faster I go. It’s even more apparent between 65 MPH - 75 MPH. So I would say the vibration gets worse with acceleration. The steering doesn’t shake when I brake. I don’t feel the steering wheel shake within city limit speeds. It’s really odd and it’s only happening on the front right tire. At this point, I’m thinking about taking it to a Lexus dealership, but not looking forward to the $175 per hour diagnostic fee.

Since the vibration doesn't appear until you're going pretty fast it would be a slight bend in the axle if that's what's going on, maybe not readily noticeable to the naked eye. It would probably need to be checked at speed. I don't know how you'd do that on a modern all-wheel-drive vehicle. Scotty has demonstrated equipment that can be used to place sensors that trace noises in a car. Maybe something similar is available for tracing vibration problems?

Yes, the vibration doesn’t appear until I reach highways speed, so it could be the axle. Maybe something exists that traces vibration problems. Thank you for helping.

Hi, this was an unrelated topic, as I have recently experienced issues unrelated to this previous post.

No, the car has not ever been in a wreck.

Assuming you got a ‘good’ front end alignment & balancing, I’d start to check the wheel bearing & CV axle as Chuck mentioned. Also wiggle the other front end parts in that corner to check for any play. If you can’t do it yourself, I’d recommend visiting another, reputed front end shop, to diagnose what’s going on. All the best!

I will have the wheel bearing and CV axle checked. I will definitely have a reputable front end shop diagnose what’s going on. Thank you for helping.

No worries & please keep us posted with their diagnosis.

It turned out to be the rear right wheel, which was bend and the tire was out of round so I bought a refurbished wheel and also installed 4 new tires and the shaking has gone away.

Excellent! Thanks for keeping us posted. Glad it was straightforward.
