Review: It worked for me - I bought a used 2007 Chrysler Pacifica that ended up having a read differential leak which turns out not to be serviceable. (You need another diff). As a last resort I bought the differential conditioner / sealer and to my surprise the leak stopped . Have since put 1500 miles on the car and still clean and dry. As a last resort I would definitely recommend.
Review: Good product - Good product, everything is fine
