Front Drive train noise 850 1997

I recently came to the conclusion that a 'grinding' sort of noise that my 97 855 was making was coming from the front right wheel bearing/hub assembly. The noise was most noticeable while braking under 20mph and the worst just before coming to a complete stop. I was not very noticeable during acceleration.

I just finished installing a new hub assembly. (pain in the butt) and took the car for a test drive. THE NOISE WAS WORSE!!! I am really at a loss now. It is not a brake noise, and it is not clicking like a CV. The only thing I can think of now is perhaps the right hand drive shaft support bearing.

I have done some searching and have not been able to find any information on diagnosing this problem. After dropping $150 on a hub that may n ot have needed replacing, I want to be pretty sure before I start spending money and tearing things apart.

Any first hand experiences with this issue would be most appreciated OR a link to a known resource on the web.

I just bought a 95 855 T5R and I need to get this 97 ready to sell ASAP. Please Help!!!

    Mileage?

    A failing hub bearing is best identified in a turn. In a left turn the right hub bearing is under more load and vice versa.

    You seem pretty sure it isn't brake related but that's where I'd look. Are you using OEM pads/rotors?

      Hi Erwin,

      Thanks for the reply. When diagnosing, it didn't seem to be too noticeably different during turns, but it defintely sounded like it was coming from the front right side of the car. The noise is clearly present under 20mph with or without the application of the brakes. The noise was also present before doing a brake job and afterwards. The brakes are Repco pads and Brembo rotors. The fact it makes the noise without brake application though seems to negate that possibility. I'm really stumped.

      I would love to find one of those little articles about diagnosing noises like this. I'm fine when I get around to replacing my shifter microswitch and front seat recline cable! Now if I can just get the damn noise to go away.

      Any additonal comments are welcome.

      Greg

        You got me then. All that's left is the CV joint and the shaft support bearing. I'd like to hear what you find.

          Well, if I find some time this weekend, I think I'm going to put the car up on stands, pull the wheels, calipers, rotors, and then throw the sucker in gear and see what I can hear with my dandy little bearing stethoscope. I know this is not the safest thing I can do, but I figure with no wheels, at least it won't run me over.
