Theres quite afew seals for the axle.
Do you have a Non disco or a CAD?
If you have a disco do you have a one piece shaft or two?

The axle seals require you pull the carrier. First pull the axles, then mark your bearing caps and be sure to put any shims back to their original location when re assembling. The axle seals can now be changed, they sit just outside the carrier bearings. Before installing the axles, remove any rough or sharp edges on the spline area with scotch brite, to avoid damaging the new seals. Also before you slide the axles in, add a coat of grease on the splines. A carrier spreader makes this much easier, but most DIY guys don't have these around their garage.

I personally think if your going to do this is to take it to a axle guy. Its really important that everything lines up right and if its not your axle will be shot faster then you would think.

And what does a carrier spreader do? Iv never seen or heard of one.

This is true, we get $300 to do the axle seals, just FYI if you take it to a shop, that's about what you can expect

Axle seals are easy, you don't need a spreader. The shimms wont fall out when you take the carrier out. The bearing caps need to be put back in the position. Hardest part is dealing with the cad

What is a spreader?

What is a spreader?

It's in the pic on my post. When installing the shims, usually very thin, this tool spreads the case a very small amount to make shims easier to install without bending them. Makes a gear change or carrier work go much faster.
And no, you don't need a spreader, but it makes the job easier.

That's intresting. I can honestly say iv never heard of one. Its gotta spread the case like thousands of inches!

I am running the cad system. I found the axle shaft seals on rock auto (1652602,1652603) What are the others?

That's right, and that's all it takes. Now you know what those two dowel holes are for on each side of the case.

Can the same tool be used for pilling the axle tubes out?

 

[JPi1]

There are no axle tubes to pull out

 

[cakes567]

There are no axle tubes to pull out

Can't you pull the tube that the axle shaft slides in off the case?
