Ok i just put a set of Voxx mg3 wheels on my wagon had the tires mounted and balanced now i get a resonably bad vibration around 50-65 it comes and goes, i tried swapping a wheel from the back to the front same issue. its not as bad while accelerating or when its cooler outside. aligment is good, could a bad bearing cause this? if it was a bad wheel balancing wouldnt it do it all the time?

 

Are all of your mounts good? Control arms good?

 

yes all mounts are good

 

the tires are all the same size?? purchased at the same time??

 

bad balance will show up as vibration around 55mph +/- 7 mph or so. have then recheck the balance and have them check to see if wheels are true. are the wheels hubcentric? if not, you're going to want to find adapter rings for them.

I'd suspect the balance or a bent wheel even though they are new. There's a chance it may have thrown a weight. Are they the rim clamp style or did they use adhesive ??

Did the shake move from the steering wheel to your "seat" when you rotated the wheels ?? If it's in the steering wheel you know it's one of the fronts. If you feel it more from the dashboard or the seat you know it's likely a rear.
