Is it possible to remove and replace the seal at the rear of the transmission tail housing without removing the extension housing? The seal is flush with the back of the housing, it seems like I could get a hooked tool or screwdriver under it and pop it out, and tap in a new one. It’s not clear from the manual how much dismantling is required before the extension housing comes off; I’d prefer to avoid it if possible.
On the other hand, the driveshaft yoke is worn and just a bit loose in the bushing, so replacing the bushing would probably be a good idea, if it’s not too difficult to the the extension housing off.
Any insights most welcome!
