Pressure lubing the the inside of the differential. Would be just about impossible on a 15. Altogether I have heard of drilling the axle housing and pressure lubing the outer bull pinion shaft bearing. Especially the left side one.
Yeap, 2 more auctions. February & March. Only a couple items have really caught my eyes sofar. Would be nice to see what’s on the next 2 auctions now. Just to see if there is something else that I should be saving my money for.
