Front Right Drive Oil Leak - B7500 with 351 hours

[Island-man]

2002 B7500

I’ve been using my tractor in 4WD to blow snow this month as January has been snowy. I noticed today that I have oil on the floor under my right front axle hub. Any feedback on confirming where the leak is and how difficult the fix would be?

Fairly easy fix.
The WSM (Aka Service manual) will go over details.

This is not a biggy labor intensive repair... I did it on my B2410. Took me longer to clean everything up before assembly than it did to replace the seal and assemble.

Good to know. Do I need any special tools? Any guess on how long it took you? I was trying to find the details in the WM, but don’t see anything specific for seal replacement.

Snap ring pliers is about the only special tool I can think of.

I did both sides while I had it in garage... took me three days (I am old and slow, not in any hurry). The Permatex liquid gasket was the 24 hour setting time one..... so that's what took the most time. Like Wolfman said... a good set of snap ring pliers is a must. I picked up a cheap set from Harbor Freight that worked like a charm.

I did run into something that I was not expecting. The new seal replacement was a one piece seal. The original was a two piece seal, the actual seal and a thin bushing that fit over the spindle. I had to remove the bushing and toss it. Other than that its pretty straight forward.
