Review on Dorman 697 704 Differential Cover Ford by Jay Buford

Revainrating 5 out of 5

As advertised - works like a master

99 F250 6.8. As advertised - worked like a champ. I replaced a rusty, leaking lid that was 15 years old. MFG uses RTV sealant, however this product comes with a gasket. Use the supplied gasket or RTV sealant, not both. The seal worked perfectly for me. There is no filling/draining with this lid. To drain, remove the lid. There is a plug on the side of the differential case for topping up transmission oil.

Pros
  • Consistent test results
Cons
  • Very expensive
