Vibration at 62mph+ but tires are balanced
when driving, once I hit 62mph+ I get somewhat strong vibrations from what feels like the passenger front. Braking has no effect on vibrations, other than slowing me down which under 62mph the vibration goes away. My first thought was tires. Had them balanced and rotated. Had zero change from this. Second thought was cv axle. But then I remembered that's only on fwd or 4wd. Mine is rear wheel drive so there is no cv. Then I thought maybe front wheel bearing but I'm not getting any of the noises typical of bearing failure. Tearing my hair out over here because going most places requires highway speeds.
Hi @brandon_k ,
Have you checked the shock absorbers?
Try the "bounce test".
Push down hard on one front corner of the vehicle and then let go. When it starts to come back up push down hard again.
Do this 3-4 times in a row to set up a rocking motion and then stop and allow it to come back up.
The car should settle back to the "at rest" position without continuing to move of its own accord.
If it continues to rock then the shock absorber is faulty.
Do this on both sides.

@jayeff bounce test is good. Both sides. From the moment I stop bouncing it to the moment it stops moving is 1 second or less

@brandon_k
Did you check the steering arm bushes and/or ball joints for wear?

@jayeff not yet. Still need to get down and check those. Think I've got a bearing going on the DS though. Grabbed the tire and shook it back n forth and it moved both when I did it horizontal and when I did vertical.

How about mud, are the wheels completely clean.
