82SC wheel bearings, how easy/hard?
hi guys,
first let me apologise for not searching this topic but i only have dial up and it takes forever on my computer. i've been hearing a speed related resonance on the motorway and think it might be the first sign of a bearing going. even if it's not i think it might be something worth replacing anyway, as i have no idea when they were last, if ever, changed. just wondering how hard/easy they are and if i need any special tools. many thanks as always. justin

Justin,
Front are relative easy. Take a look at the bentley manual has great pictures. Rears, I don't play around with. Never tried , but have heard enough form others. Earl

I would spend more time trying to pinpoint the problem. Does the sound change when you make a turn? Typically a bearing that is on it's way out will be quiet during straight-ahead travel and only make a groaning or whining noise when it is more highly loaded during turning (this also helps to diagnose which side of the car has the suspect bearing). You can also check for any excessive play in bearings.
I've found that worn tires can create lots of noises that get attributed to everything from transmission problems to wheel bearings. Might check the tires, too... The fronts aren't too bad. The rears are more of an undertaking, but not that bad either for the typical DIY person. Mike

The rear bearings are not for the faint of heart unless you get everything lined up before you start.It is not very complicated mechanically,but the removal/replacement process can be a real 'female dog' without the right puller .I spent a lot of time cursing underneath my car, until I gave up and bought the tool through our host.But now I have the urge to replace all the bearings just on principle!!!.Is there no end to this insanity?

As far as the fronts are concerned, the outer bearings are the ones that usually go and are easy to replace without removing the rotors if you leave the old race alone. I would go ahead and pick up a set of outer bearings for about $7.00 ea at the parts store and see if that fixes your problem.
Cheers, Joe |

thanks for the info,
i'll try and find a quiet hill and turn off the engine and roll down to see if i can identify the problem any further. of course it could be tyre noise, the rears are new so if it would be the fronts if this was the case. i would imagine the fronts get the most wear so i'll replace the outers anyway and see what happens. manny thanks once again. regards justin
