I bought an '89 4WD Suburban for its 700R4 transmission and swapped it into my '79 Sierra Classic, pictured here. There have been a number of challenges but that side of the transaction seems to have gone okay and the PU is like a new rig.
On the other hand, the 350 going into the Suburban is a different story. The transfer case is very noisy, I think the front driveline spinning might be causing problems with the automatic hubs.
The Suburban got stuck in 4-Low so I had it towed back to the shop. When I went to pick it up a tooth in the rear diff seems to have broken and now needs replacement. Might the shop have mis-installed the tranny or driveline to cause that gear to break? And do I need to change the hubs? Should I put auto hubs on my '79?
