I am about to the point of parking the truck and finding something cheap to drive until I get everything fixed. I am having problems with the rear axle, transfer case, transmission, and front axle. Basically everything listed needs seals or bearings.
The axle shaft bearings are gone, noticed the other day that there was alot of play, able to move rear tire up and down. So, I think it is just time to upgrade to either a 8.8 31spline or bigger. The d30 pinion yoke is leaking again, this is the 3rd seal to replace. Going to get a new yoke. Transmission bearings are so noisy now that they chatter all the time. So another rebuild is needed, this time replace all bearings and synchros. The transfer case is leaking so much oil, that every 1000 miles it needs another quart. So either look for a 1354E or try to wire up a 1354E.
The engine has 200k miles now so replace it, rebuild it, or just new seals and bearings?
I think my wheeling days are done for this year.
EDIT: front driveshaft is bent so I want to get a new one made from Tom Woods
