S10 Front Differential Oil Leak

Showing 4 out of 4 Posts
Question From JR66 on S10 Front Differential Oil Leak

Does anyone have the procedure to change the front differential pinion seal on a 2000 Chevrolet S10 V6 4X4 pickup? I put it in 4 whl drive for the 1st time in quite a while and the seal started leaking a lot after that. I think because the front driveshaft hadn't turned in a long time the seal hardened or some rust formed. Anyway now I get a puddle under the car overnight and I'm reluctant to drive it too far for fear of running the differential dry. It took quite a bit of oil when I filled it. If I take out the frt driveshaft what do I have to do to pull the pinion out and change the seal? Can I do it with the differential and axles in place?

Response From re-tired

Loren is correct . However, the job is much easier with a airgun & impact socket. Your dealing with a high torqued nut plus years of rust. The procedure is the same either with breaker bar or airgun. Undo drive shaft from yoke . Scratch or paint a ref line across nut and yoke . Undo nut,slide yoke off . Remove seal , a large screwdiver will do. Cleanup yoke where seal rides. CAREFULLY tap new seal in place. Put a little clean lube on yoke and install yoke and nut. Tighten nut till ref line aligns . Re-install shaft . Refill lube . Have your fav beverage or pay the shop. And they will have one for you.

Response From JR66 Top Rated Answer

Many thanks to both you and Loren for your advice. I have air tools and am used to rust. My main concern was whether or not I had to remove the differential. That would make it a really big job. Now that I know I can replace the seal with differential in place I'll give it a go.

Response From Loren Champlain Sr

Can I do it with the differential and axles in place?
Yes.
