The front end of my '98 V70AWD makes a deep rumbling vibration sound while accelerating through left turns. The vibration can be felt slightly in the steering wheel. It only occurs while powering through left turns. Never when going straight or turning right.

My dealer just replaced the left front wheel bearing and the left front axle assembly. No joy. Any suggestions?

Thanks,

Broken upper and lower right motor mounts. I just went thru this 6 months ago on my AWD.........was absolutley convinced it was a CV joint but when I actually got underneath and started to yank on things....the motor was actually moving about an inch or more.........sure enough both the top and lower right mounts near the cranshaft pulley were broken. This is a do-it-yourselfer and you can get the parts from FCP Groton. The upper mount will be an harder urethane mount......much easier to install than a factory one but it is stiffer so you will feel the engine more only on start up.

Hey Masher--

You called it... I had a broken lower motor mount. The rubber appeared OK, but the metal insert was broken. Problem solved! Thanks very much for your advice... The dealer was stumped until I mentioned your suggestion to them.

Gratefully,

Thanks, Masher. This is good info... I'll check it out.

This may be unrelated, but when my motor mounts went bad, I noticed it during idle, but especially during lefthand turns.

I have replaced the front wheel bearing assembly on my S70 using Bay 13 instructions. The bearing assembly cost about $150.
