Vibration when turning

New member and my first ques. We just got a 01 monte ss  and have a problem I could use some help with. When I drive at highway speeds and go thru a right curve while accelerating it vibrates thru the floorboards and driver side door. No vibration thru the steering wheel. I talked to the people we bought it from ( my daughters in laws) and they said they had the wheel bearing/hub replaced about a yr ago but didn't fix the prob. Any ideas?
thanks

Check the axle out
Might be the cv joints going bad
And the other things that I would check would be the engine and transmission mounts.

tried rotating tires left to right to see if it moves?

Thanks; I'll check those things out.

is it only when you turn one direction??  does it make any noise along with the vibration??

Only when going around a right hand curve at highway speed and giving it gas. If I coast thru the same curve it is fine. Maybe a slight grinding sound, but my hearing isn't the best.

how many miles on the car??  it could be a front hub assembly...or a c.v shaft...
 
sounds to me like one of those 2...hubs are common on these cars...luckily they're not that expensive considering they have the sensor on them...dont get ripped on it if thats what you need...try to get a BR930548k hub from a auto parts store...cdn its about 180 or so + tax, so i could only imagine its cheaper in the states...dont buy anything cheap...and the delco ones aren't really the greatest either

124,000 miles. The people we bought it from said they had a bearing/hub replaced about a year ago but that didn't solve the prob. I don't believe it could've been this bad for a year tho. They offered to pay for the repair but, if it's something I can fix myself I'll go ahead and do it.

It was the inboard CV joint on the left side (drivers). I replaced the axle and no more vibration.
