A greasy oil film around the pinion flange and drips on the back of the rear axle are a classic sign of a tired pinion seal on the 122 with a Spicer axle. This category gathers the parts you need when the leak has to go and the final drive is to be reassembled with the right preload again.

The group includes oil seals and gaskets for the pinion and differential, bearings, shims and washers for setting the pattern and backlash, plus grease, an inspection cover and a sealing plug. The shims are central – if you only replace the seal without checking the pinion preload you risk noise and a fresh leak.
The parts are gathered for the 122 (220) with B18 and the Spicer version of the rear axle. Since Volvo used several rear axle variants over the years, it is the version, not just the model, that determines which seals and shims fit.
