What are some of the volvo v70r awd problems?

Some of the Volvo V70r AWD problems are an angle gear leak on 5 cylinder AWD Volvo model years 2001 to 2006. Oil leakage/moisture from the angle gear halves can be resolved by resealing the housing and replacing the seals. The angle gear itself does not normally need to be replaced. There are two reasons an angle gear should not be resealed and instead should be replaced. There is angle gear noise/binding while driving. There is angle gear backlash, bearing damage, or excessive pinion shaft play found during disassembly. Volvo put out a service bulletin because so many owners reported having this issue.
