  • Transmission seal

    I'm swapping 4 speed to 5 speed. Should I replace all the seals or just what I believe the output seal (where the axle slides in)?

    It's cheap insurance to replace the output seals while it's out.

          I would replace the seal on the input shaft so there won't be any leaking behind the engine. That would be more trouble by far than the output shaft seals would be.
          When I'm good I'm very, very good and when I'm bad I'm HORRID.

            How difficult is it to do? Not very familiar with transmission.

              I don't find it difficult at all. I just used a big screwdriver to pry it out ensuring not to scratch where it mounted. Then i tapped the new one in with a block of wood and a hammer. I found the hardest part to be finding the correct seal. The one they gave me didn't match the one in there. I had to bring the old one back to match it.

                One more dumb question just to make sure I'm ordering the right parts. Does anyone have Autozone part numbers for the seals?

                I come up with one seal that fits all 3 and then I have seals with 3 different part numbers for each side and then the input.

                  This is what I see when I select output seal. Ones for the left and ones for the right.

                    Buy the ones from rockauto. Buy the Timken bearings. They are best. Hands down.

                    There is a rockauto discount code that can be found by a search for "discount code"

                      That's for the front hub. I believe the OP was asking about the transmission output seals where the axle shafts ride.
