    Anything else I should replace while doing Center Support Bearing?

    Mechanic said I need to replace the Center Support Bearing since the exhaust will be down? I will also replace the Guibo but was wondering if there is any other wear and tear item I should replace? Thanks.

    You'll need exhaust gaskets The guibo will also need new bolts and nuts. There's really nothing else in there. You can do a fuel filter since the car up. Diff fluid if it's close to time. Maybe trans fluid since the heat shield will be out of the way.

          Inspect your diff input seal and make sure its not leaking. Its not a "while you're there" thing but some of the work overlaps.

            Make sure you order a new seal between the cv joint on rear driveshaft that bolts to rear diff. My car is stuck on the lift right now bc i forgot to order that

              I second that on buying a new driveshaft gasket seal to diff- btw it has self adhesive so it can stay in place. Wasn't obvious to me the first time i did that job.

                  Order two of those drive shaft seals as they break really easily and they are cheap. ECS had to send me three before I got one that wasn't broken.

                      It goes over the top of the CSB and sticks to the top of the tunnel. Secures the top in place and minimizes vibration.

                              Same experience. Then when I finally got one that wasn't broken on arrival, it was so old and brittle that it broke taking the wax backing off of the sticky side smgdh. Ended up just JB-welding it back together and threw it in because it seemed impossible to guarantee that I could get one that was both fresh and intact.
