27. Installing the speedo drive gear and carrier bearings. The drive gear tabs will need to be filed/ground to allow the carrier bearing to seat properly and flush. The Mazdaspeed Protege does not use a speedo gear ring. It gets it’s readings from the ABS sensor(s), so the LSD is not machined to accept the speedo gear ring needed for non-ABS cars.
30. Once you have your speedo drive gear and carrier bearings installed on the differential, it’s time to re-assemble the transmission. Start by removing the old carriers the old bearings ran in. This may require a special pull tool. Be careful not to damage the transmission case, remember it’s aluminum!
31. Now you can drop the LSD into place. Make sure to add some assembly lube to the carriers and the bearings.
