DIFFERENTIAL ROLLER (BUDGET)

Two of these main diff carrying bearings are required in the gearbox and this new steel caged type fits either way round--The 3/4" width outer track type had a side marked "thrust side" which must face away from the gearbox. These usually shim up at 4 thou pre load as opposed to the very early non thrust type bearings which were 1-2 thou.
If your finances allow it, you should prefer the better quality RHP branded bearing.
