View Full Version : front IFS diff gear help

09-18-2006, 02:42 AM
Earlier this summer I put my new 5.9 geared diff in my Toy.

I turned the hubs into lock as I have put Warn Manual hubs instead of the ADD hubs. I drove about 5 miles and the truck slowed down and the front end went bang then started to pick up speed again. I pulled over ASAP and felt around he diff case looking for a break. No breaks or leaks but man it was Fn HOT!!

I came to realize in my haste that I forgot to put in diff oil.

So I am looking at putting in new spacer , front bearing, then rear bearing , spacer, oil slinger and oil seal as these are most likely not reusable again anyways after being cooked.

What I am trying to figure out ( going by this webpage http://personal.utulsa.edu/~nathan-buchanan/93fsm/suspensionandaxle/24disas.pdf )

is when i put the bearings in and the spacer being new I would have to find out what the torque values are .

Any tips on doing this? I bought a dial gauge and magnetic base to try and learn this stuff for myself. Any pointers would be much appreciated. Just need to round up the parts.

oh yeah almost forgot.

I put oil back into the burnt diff. No difference. I go to put the t case shifter into 4 lo or hi and the indicator light comes on for a very brief second and will not stay in 4 wd.

WOndering if the burnt bearing might cause this or if it could be the the intermediate shaft in the clutch case or maybe the clutch hub?

Any smart ways of figuring out this problem? I need to get this done before winter or find a cheap 8" rear diff with 4.35 or 4.37`s whatever the ration and put the stock IFS diff back in since it works.

Thanks guys.

The original stock geared IFS is fine, the 529 IFS diff is hooped.

The 529 rea 8" is fine and the stock rear 8" is hooping now

So I have one of each that is good and one of each that is gone.

if the IFS 5.29 r&p is fine still then just swap it into the stock ifs 3rd

guess i could do that.

Figured I might as well replace all bearings etc while I am in there. STill need to pick up a few tools like a micrometer etc.

Send me a day and I will be there. I am sure these guys could show me better ways to do it and teach me other ways. I have not done many of the hard gears but the stock gears are easy. Worst I did was a 5.71 and it worked great but had it pointed into the air and got no oil in it so my claim I did ! but it didnt get fed. :( :D Ty, Mail me to tell me aday ahdead so I can make it. Thanx bud!
