Symptoms
Oil in the yellow swivel boots, oil pouring out when you open a wheel drive filler, high oil levels downstream of a low diff.
The fix, step by step
- First rule out an overfill.
- Each unit has two plugs, and the filler is the lower one: fill until oil comes out of it.
- Then check the breather on the central tube.
- Owners report that the axle-tube O-rings are a weak spot on diesels: early P90s and P80s use the same O-ring as the 710/712, while later P90s and P93s use a plastic ring and sealant instead.
