Hi, all...I work on my son's 91 RS..just did the hoses, calipers, pads up front..still have a buzzing, humming, kinda grinding sound that follows wheel speed...never heard anything like it..all front end seems tight, no plat in wheel bearings, etc..got 157,500 miles on it..anybody have this kinda noise from tires?? Goodyear Eagles, new in November with alignment.. Ant Ideas?? Great Site!

 

First thing I'd change from the sound of your discription is the wheel bearings and races. Slotted rotors will sometimes buzz a little but you did not state you have them.

 

Thanx for the whhel bearing advise....I was thinking that was the next step....
