Hello everyone! I sometimes find myself on this forum for some quick pointers to help the job go a little more smoothly, and to this i say thank you! Here is a little contribution i would like to make to help someone else save some time.
Car 1986 Alfa Romeo Spider
Symptoms: Rear end noise so loud you wanna drive off the bridge
It all started with a sound similar to a loose exhaust clamp. I looked everywhere and could find nothing. Slowly the noise got worse and started at a lower and lower speed. At 50-75mph it no longer sounded like an exhaust clamp. It started to sound like an inconsistent whooshing noise (wowowowowo). I then drove in the far right lane on the highway to locate the sound from the echo off the highway walls. I found that no sound was coming from the rear on the drivers side, and the sound was in fact coming from what sounded like the rear passenger wheel. The noise eventually became unbearable and i was afraid of doing further damage, so i parked it until i could get time to work on it.
That day i called international auto and ordered seals and rear wheel bearings. The guy on the phone gave me a hard time for buying just bearings and said its my rear end... pfft i know better than that... Even in the event it is your rear end, you want to eliminate all possibilities before you spend 1500 on a new differential. From my experience with other cars i have worked on, the differential makes more of a thudding noise when it starts to go bad.
Okay now for the good stuff...
1) Shop press
2) Assortment of press dies
3) Large Impact Sockets 10mm-35mm
4) Torch with map gas
5) Screw driver and socket sets
7) Pb blaster
9) Shop towels
Steps for installation of new bearings
1) Spray pb blaster on all hardware you plan on extracting
2) Extract axles from the rear end
3) Remove disk plate and hand brake assembly
4) Press bearing and retaining ring out together to simulate special tool A.3.0394 (see photos). I thought that removing them was much harder then installing them especially when you can only find threads that show installation.This was the setup i made to do so.
5) After they have been pressed out, do these preps.
Prep shaft with scotchbrite, but only enough to shine and debur. Be sure to chamfer the backside edge of the retaining ring only enough to debur with 320 grit sand paper.
6) Before pressing on the new bearing spray shaft with wd-40 or equivalent make sure you put the spacer, bearing, and retainer in that order.
7) Press in spacer and bearing
8) Press in retainer
9) You can check to make sure everything is pressed in correctly by lifting the stud plate a bit and checking for a gap.
