Re: Replacing the driveshaft oil seal in Differential

On the floor with hand tools? Yes... depending on your desire and/or 
dedication to the task... I wont.

The first requirement is to measure the rotating torque of the pinion...
it 
is im****tant that the bearings be returned to near the same preload as
they 
had before the disassembly.... The pinion nut is TIGHT.... You'll need  a 
decently long lever and some way to hold the pinion from turning.... Air 
tools can help, but they need to be used carefully and wisely to keep from

"gaining" preload.

Service manuals need to be read carefully... The pinion seal isn't a 
"zip-zap" deal.... but I will admit that many have made it a "zip-zap"
deal 
and have had luck on their side (these are the guys that will call this 
repair a "no brainer". I'm top heavy on apprentices at this time... and
this 
repair is far from a "no brainer".... a mis-step can be very, very spendy.

DAMHIKT.

These same service manuals can either explain the repair in great
detail.... 
or be written by someone that assumes the reader has some previous
knowledge 
and experience. If you find a service manual that has an inch/pound torque

wrench in the required tools list and mentions "rotating torque" in the 
procedure.... this is the one you need. IF (and this is a very big IF) you

have "the feel", you can probably do fairly well without the inch/pounds 
torque wrench... After nearly 40 years, I still reach for it regularly....
