I have a 96 Seville STS. When my car is going 20 + mph and I make a slight turn to the right, I get a noticeable hum, maybe a grind, coming from the driver’s side wheel area. The farther I steer the wheel to the right the louder it gets. When I steer it to the left the hum goes away.
I thought it was the wheel bearing. I’ve changed the bearing even though it didn't sound like a bearing going out to me. It didn't help. The noise still comes in when I turn to the right and goes away when I turn back to the left or hold it exactly center. I guess I ruled out a wheel bearing; Lot of money for poking in the dark.
Could this be in the magna steering mechanism?
Any thoughts as to the problem. There’s nothing rubbing against the wheel.
Maybe it's noise from the other wheel bearing?
The same thing just happened on my '94 Deville! I replaced the wheel bearing, but am still getting this low growl noise. I can only assume it's the axle shaft on the drivers side. I would guess that's what's wrong with your STS as well.
And the same thing is happening to my 94 eldo also... I don't think it's the CV half-shaft though because when I crank it all the way in either direction and do circles, it doesnt make any noise... After hours of searching, I think I may have found what was causing it, but I'm not sure. It seems that my inner tie rod end on the passenger side is going bad which might be allowing that wheel to vibrate when turning right and accelerating. Again, I'm not absolutely sure this is the cause, but it's a very likely possibility IMO.
Well guy's I found out the problem. The other bearing. I changed it out no noise! good lesson when you change out one bearing change the other. Especially when your car has 120,000 miles on it. sounds brand new. thanks for your help.
Those cv shafts should make a clunking noise if you turn the wheel one way or another if the shaft joint is bad. Turn the wheel and go backward you should be able to hear it well then. I suppose it will be more noticable the more worn out it is. but you will hear it. Hope this helps.
Hey guy, first post - my 1996 STS is immaculate, inside and out - my only problem is the one described in this thread, I couldn't have described it better. I'll keep in touch with what I find out about it.
I had this problem - a "rattling" on right hand turns. I had my CV joints replaced and it didn't fix it... a year later when the starter needed replacement the sound went away. Turns out the old starter's gear was sliding on the turns and hitting the flywheel causing the noise.
