So the one part of this whole ordeal i haven’t mentioned is the T case issues.
So upon pulling the drivetrain out of the Burb, we discovered my T-case was cracked half way around the rear half of the case. It fully explains the bad leak i never bothered to diagnose and the drivetrain vibration ive been chasing, thinking it was driveshaft issues the whole time.
The problem is, its a unicorn t case. Its an np241, which chevy started using in ‘88 with the body style change on the trucks....but my suburban is part of the 88-91 carry over years for the Blazer, Suburbans and fleet v3500’s. Its passenger drop and next to impossible to find a 32 spline, passenger drop chevy np241. And few companies offer remans and even then, they’re $1500. Notpayingthatmuch.png
After some searching, i found a used rear case half on ebay for $150, and bought a rebuild kit from Off Road Design for $120. I’ll have less into fixing and rebuilding mine than I would buying a used complete unit.
Pic of the crack below. Parts arrive friday. Hopefully have it running this weekend.
