Hey there guys.. just got my 3.90's put in maybe 2-3 weeks ago.. took my car to get the right exhaust pipe moved a bit to the right and they noticed oil on the bottom of the gear box and continued to say the front pinion seal was leaking... how much oil can I expect to have lost/lose until I get the problem fixed? Note - I didn't notice a lot of oil.. just some residue on the bottom of the gear box.. dunno what to do
