Thread: Rebuilding r380

Pretty straight forward box to do , especially if you're familiar with doing boxes in the past and definitely worth doing if there is bearing noise ,.
Get a master kit from Ashcroft's as well as a shim kit, and do the Synchro's while you're at it,
Take your time , the longest part is setting up main and layshaft preloads
Probably a full day to do ( box already out)
Hydraulic puller kit gets the rear output seal collar off easily ( they're tight)
If you're going to be towing etc its also worth getting the heavy duty rear bearings and getting a local machinist to open up the recesses in the rear housing to suit

Do you know the part numbers for the larger bearings?

Been about 9 months since I did one with those bearings , pretty sure I had it written down , along with sizes, have looked but it must be somewhere safe
Just a matter of getting the bearings along with the other bits , after all , I don't mind paying a bit extra for their r and d, they sell good stuff.
