Replacing the Carrier Bearing
One of the things that seems to rapidly wear out when you lower the Hardbody is the Driveshaft Carrier Bearing.
While I think mine was on its way out (vibration cruising at 55km/h in 3rd only), I replaced it. Turns out it may have been just insufficient pinion angle and not the bearing. Though the bearing did have a bit of play in it…. Nevertheless, here is how to replace it:
Replacing the carrier bearing was easier to do than I expected. Book time is 1.2hrs, I did it in 1.3 and was not hoofing it to do so.
Pull the driveshaft out of the transmission (fluid shouldn’t leak out, but be prepared for it if it does) and put it on the bench. Center punch the flange and the shaft so they can be re-assembled the way they came apart.
Thin coat of lithium grease on the shaft and install the new parts with the provided new copper washer and nut. Check your alignment marks that you made. The bearing should have marks to indicate “front” – mine had “F” on one side.
