Replacement Axle Assemblies from SurTrack.....

[VehiTONY]

It sounds like your on the right track. The entire green cup moves. And it is leacking behind the cup. Which makes me wonder how if the green cup was not removed since they are half shaft replacements. I would appriciate some pictures though. If you have time pales send them to me at tony.c.0313@gmail.com. I'm taking it back to the mechanic to have him inspect it. I hope it is a easy fix since I am broke at the moment.

Take a look at the link that Tom posted. If you click on the first of the two downloads in the thread you will be able to see the axle assembly on page five, six and seven. That is about the same picture that I would take of the one that I have at home so we can use it and the diagram that Scott posted to figure it out.

Just like Scott said, it is probably your axle oil seal that is leaking. The axle is mounted to the axle housing by a plate (#7 in diagram from bartmanS4) with four bolts in it. That plate has mounts on it that, in turn, mount to the frame to hold the whole axle housing in place. The axle (with the green cup - #9) slides through a hole in the plate and then on into the axle housing (#1). Once the axle is through the hole in the plate you then slide on the oil seal (#6) which snugs up against the plate and is then press fit into the axle housing to stop the fluid in the axle housing from leaking out.

After the oil seal is on you would then slide the first snap ring on (#5) to keep the seal in place, then the axle bearing (#4), then the last snap ring (#3). Once all of that is assembled outside of the axle housing, you would then feed the axle into the housing. When you do that you, or your mechanic, would need to be careful because as the bearing and the oil seal seat into the axle housing you could pinch or mis-align the oil seal which would cause a leak. I believe a leak is what prompted Bart (nfpgasmask) to do his front axle rebuild - http://blog.isuzugeek.org/2011/08/ve...e-rebuild.html

I haven't had to do it, but from what I understand replacing the axle oil seal isn't necessarily a tough job, but it is a bit time consuming (Tom's diff drop write up shows the front axle removal).

I hope some of that helps. If you still need pictures let me know and I'll take a few tonight.

The green cup could have been removed.

We all talk about the easy method (see MechaTech boot install instruction in the Download section).

But ... the shop probably didn't know of that method & could have dropped the entire axle assembly in order to remove the bad 1/2 shaft. I had to go through that whenever I installed the diff drops on mine. It's quite a bit of work to go through if you don't have to.

The seals are probably not very expensive. If you & a buddy or 2 are willing to give it a shot, you can do the entire job in your driveway with common tools (might have to pick up a few at Harbor Freight - but you're probably still looking at less than $100 to get'r done).
