I put a 68 4.10 chunk in my 1 ton panel and the pinion seal is leaking. Can someone advise me as to what size socket is supposed to fit one the nut. Thanks. | | |

Also, inspect the pinion shaft. Mating surface needs to be smooth. If it is gouged or scored, get a redi-sleeve to go over the shaft.
Lacking a 3/4 or 1" impact wrench, the best way to tighten the pinion nut is to put the rear wheels on the ground (or ramps), put a big pipe wrench with a cheater if needed on the yold so when you tighten the nut the pipe wrench is against the ground. Then you can use a long cheater on the pinion nut wrench.

These older rear ends have a LARGE double bearing set-up that is about a big as one in a log truck
