is this something that can easily be done? Drop the driveshaft , replace seal..is there much more too it?

is there any write up's on how to repair the damaged seal?

 

Nothing a good impact gun can't handle. Get a 1.25 socket and undo pinion nut, tap off yoke with a good size hammer and replace seal, put yoke back on tighten nut with a little bit of red loctite and snug pinion nut with gun slowely until you just see the pinion nut slow down. Try to tighten it up with the impact gun on it's lowest setting first, see if pinion will move in and out - up or down, you want to take out the slack and just put a very stight load on the bearings. They will start to feel sticky if you went too far..

 

is that it?

how long do u guys say it will take 1hr-2hrs? or maybe even less?

does the driveshaft need to be balanced afterwards?

 

Just mark where the driveshaft to the yoke and reinstall after done.
