exactly like the title says. i can turn sharp with no noise, but as soon as i put some throttle into a turn I am getting a distinct grinding that I can even feel through the steering wheel. what is this?

cv shaft?
bearing?

[dykaar]

If there is no grinding at no load in corners, then its probably NOT the wheel brearing. Check the CV boots. Any tears, missing clamps? More play in any individual joints?

A friend in grad school once backed his old rabbit out of his driveway, and all the CV balls fell out.

YMMV,

Ken, go to a parking lot and put the car in reverse. Turn the wheel to full lock and drive in a slow circle. If you hear a clicking noise, it's most likely a CV. CVs are usually clicking noises and bearing are more of a grinding noise. You can also jack the car up and push and pull on the top of the wheel. If the bearing is bad, it will have some play in it.

Most likely the CV joint.. I have the same thing right now. I didn't know what the noise is until I saw HUGE tear in the CV boot. New axle ahoy!

Outer CV joints when bad make noise in turns.

classic college stuff.

well it's not doing it that much right now, but I'll shimmy under to have a look at the CV boots tomorrow.

Here's what my boot looked like when I discovered it.

haha! this happened in my last car! i was on the freeway when the car started to collapse! good times...

Time to close this thread out with some useful information!

This grinding noise persisted and got worse. It would mostly do it accelerating from a stop with some torque on the engine. Then it got so bad that it would actually do it while I was stopped. That was worrisome, but at least it ruled out driveshaft stuff! The noise was distinctly metal on metal and could be felt through the wheel and floor.

Had my mechanic listen to it and the first thing he said was lower engine mount. Took a look at it, and sure enough that sucker was shot. You could actually see the engine was sitting too low!

One good way to diagnose this is to grab your oil cap and see if you can move the engine side to side. If it doesn't budge, it tells you that the engine isn't being supported by the rubber of the engine mount. It should have some give to it.

Hey Guys:

Don't end the thread yet! I've got a '98 V70 T5 and get the same situation when turning left and giving it some power. I shook the engine and it seemed to wiggle a bit. So I'd say the mount is good (maybe?). Did this happen to you only when turning left?

Actually it started out when I was turning right. But it degraded pretty quickly to doing it all the time...

ken i presume you are talking about the front eng mount that Rich has a write up on? or a diff one?
