Have a droning (humming, not grinding or ticking) noise in front end of my envoy. Changed the right cv shaft. Slight improvement only. Droning continues. When i turn slightly to the right, the noise subsides. Symptoms are the same when in auto AWD and when in 2wd. Thoughts?

:thx

How do i confirm the problem?

hi, welcome to the site.

I suspect te bearings are the problem; however was looking for some mean to verify the problem and be sure i am replacing the correct side. How can i confirm the problem is the bearings and which side the problem is on. Its hard to be sure when i am driving the vi=ehicle.

you have to raise the front end and check each front tire individually.

heres a youtube vid that might help

It probably would be prudent to change both at the same time. It may not be possible to tell which one is bad at this point.

If you don't want to pay the price of the Timkens, look for Detroit Axle on Ebay, they have been reported to be of fairly good quality, stay away from China garbage.
