Last night I was driving home and I notice when my car went above 80mph, the steering wheel started to vibrate. Since I do mostly city driving (>95%), I never notice this problem before. Any thoughts?

tire balancing?
alignment?
wheel bearing?

 

check all of the above and warped rotors....

 

warped rotors will cause this? Please read one of my previous thread,

Can this be the reason?

 

My 97 max did exactly what you describe until yesterday, when I had the axels replaced . Now it is pretty smooth at 80 and doesn't vibrate but just a hair when I go around slight curves on the highway at 80ish but I am pretty sure thats because I need to replace my tires cause they are pretty worn.

 

tire balancing and unevenly torqued wheel lugs.

 

check your tire pressures too.

 

I got this same problem with my 97 too and my alignment is off too....just never get around to getting it checked out....itz getting really annoying too....but I will real soon....guess I'll check the stuff mentioned...

 

balance or alignment. My other car was doing that like crazy too....i'm leaning more towards balance.

 

I would put a vote in for checking the torque on your wheels. Mine were overtorqued at a tire shop and it vibrated kind of bad. I took off the wheels, then retorqued the lugs all to the exactly the same specs and the vibration went away.

My car has new tires, new wheels and a recent alignment, too.
