are the cosworth rear bearings compatible with the xr4x4 ones? (lobro + discs)

James

I'm not sure there's any difference between the cosworth bearings and any other car. Check with your motor factor and they'll be able to tell you (or just grunt at you, if it's anything like my local oparts place!)

or check the part No's on Burtons site https://www.burtonpower.com/default.aspx" target="_blank">https://www.burtonpower.com/default.aspx

same part hub carriers are the same

Talked to my local motor factors today about the very subject, their are 2 types of bearings for the rear or sierras, one for pushin type diffs and one for lobro, the ones for lobros are quite a bit bigger.
This is because the pushing type ones, the bearing faces are fitted against the driveshaft itself, but on lobro the end have longer splines and the drive flange ends slide over the splines and the bearing faces are fitted against this outer sleave.

Thanks guys, I hoped they would be OK and it seems so
