This is a 1972 Blazer on 1990 Chevrolet Blazer

The u-joint on the transmission side gave out with the drive shaft falling when driving slowly. Oil is pouring out of the differential. I assume I will have to replace the differential bearing but could their be more damage to the differential? It has positraction. I do most of the work on this vehicle. Thanks!

Did the drive shaft yoke come out with the drive shaft? In other words, where is the oil coming out of the differential? If it is coming out of the differential pinion gear area, it could just be a damaged pinion seal, which can be repaired by you.

The drive shaft disconnected at the u-joint at the transmission. It did not come out of the differential. The oil is coming out of the hole where the shaft enters the differential.
