Ok my post failed in the tech section so I'll give it a shot here. So I'm getting ready to install some gears on my car. My question is, how necessary is it to change all the bearings, gasket, seals. etc? My car has 65K miles and I'm wondering ifI should get the american muscle bearing kit or just the installation kit, which is the same but without the bearings. Or shouldI just make the swap without changing anything?

Edit: My car has no rear end problems what so ever.

 

change everything while you have it opened up. you could probley get away with not doing the wheel bearings but get the master rebuild kitjust in case the wheel bearings start to leak then you will have them. just my .02 this is what im going to do when i rebuild my diff and install gears. good luck
