If any components are damaged, replace them (U-joints or CV joints).
Clean the mating surfaces on the differential and transmission.

4. Install the New Drive Shaft

Position the new drive shaft into place, aligning it with the transmission and differential.
Bolt the drive shaft to the transmission and then to the rear differential, tightening to the manufacturer’s specified torque values.
Reinstall any protective covers removed during disassembly.
