Bad CV Axle/Vibration

Hi,

I have been receiving a vibration when going over 35mph for the last several months. I notice the vibration especially while accelerating. I'm pretty sure I have a CV axle issue. I checked both CV axles and did not notice any cracks/grease leaking. How do I know/check to see that if CV axle/axles are bad?

Thanks

You usually cannot feel anything in the axles, its something that need to be disassembled and inspected. Lots of miles? Then they probably have some wear in them. I just had a '01 GP with a bad vibration on accel, really bad under load on the highway. Turns out both the lower ball joints had bunches of play, so check yours!

could also be motor mounts. Check those while you are under the car.
