i have just replaced my rear diff centre after the bearings went in it. while it was apart, i had the rear wheel bearings and my drum brakes shoes and cylinders replaced. all was professionally fitted to the axle, but i fitted the axle back into the car myself, and replaced the outer seal at the same time. now, with the car still jacked off the ground, i can spin both tyres and they both spin waaaaaaay smoother than they used to, however both make a wierd noise that the old bearings never used to. being the same sound on both sides im thinking it may be normal, but better safe than sorry. the sound is hard to describe. closest i could do is a light tapping, the speed of which is directly proportional to how fast the wheel is spinning...

have i stuffed something up??

Stupid question, did you remember to put Oil in the Diff ?

I am guessing its just because the oil hasnt flowed into all the nooks and cranys yet so you are just hearing metal on metal, teeth on teeth as you spin the tyres...

Hold one wheel still & spin the other, if the noise is no longer there it's the planetary gear's.
The drum could be touching the backing plate to..

no theres no oil in the diff yet, i wanted to make sure there was no problem with the bearings first. and no, i have NOT driven it yet, its still on the stands... but if thats the issue, then i'll fill it up tomorrow morning. thanks!!

I got something right!!!

The new shaped swift's make a noise in the diff while running on the hoist that make you think the g/box is about to implode....
