Great write up - THANKS!

Are most people that do this job cleaning and packing the old bearings or replacing them with new bearings?

does anyone have a good source to buy the sst
the local stealership wouldn't sell me one and told me to try snapon
i made a butch one to get the job done but i would rather have the correct tool
 
Aside from the brakes(lucky), and the lockers(luckier!), is the axel breakdown the same in my 91?

Funny you ask, I just got mine from Dan today. Call him up, Im sure he still has some. Part No. 09509-25011
 
Does anyone have a picture off the sst?

There was a thread a few years ago with very good pictures of the SST and a wide variety of home-made tools to do the same job.

Try searching and let me know if you come up empty. I can probably find it with some time. Use the p/n supplied above. Maybe "OTC rear bearing" or "SST rear bearing" or something like that. Limit your search to the 80-section.

i thought i remember hearing speak that when you pull the axles out, to be sure if you have a locker to engage it....i think engage, otherwise something about the spider gear falling down and having to take the rear end apart to get it lined back up. Someone, know what i'm trying to talk about here?

Had this happen to my 80. I was able to line everything back up using a flashlight and broom handle from the hub.

It took two attempts, but the axle went in.
 
Bringing this thread back because its awesome, and I did it today. It needed to be done because the rear axle sat in a river for a few hours when I was stuck. Water was up to the frame. I figured water got in through a seal or the breather. Pulled it apart and there was no water anywhere. The seals and breathers did their job!

Notes:
-I was able to lock the rear locker easily by setting the rear axle on jack stands, turning the key to on, locking the cdl, locking the rear, and rotating one tire. Click!
-There was very little grease left on the bearings. Lots of gear oil though.
-I could only get the cone washers to pop out by screwing some bolts into the axle flange.
-Parts cleaners are very very useful. I wish I had one.
-What is the perferred method of removing the big seal? I pried the small one out with a screwdriver (carefully), and the large one by beating on the inner race outwards with a perfectly sized pipe.
-I could only get the small seal flush.
-I hate phillips head screws.

Seal puller... same one pictured in the front axle service thread. Put the hub in a vice and be careful when you pull the seal because the inner bearing might go flying across the garage and bounce off the concrete a few times and you will have to call Cruiserdan and get a new one. Not that I would ever do something stupid like that... but *you* might. :D

I hate phillips head screws.

Yep, and those are easy to mess up.

how much did it cost

how much did the project cost you for each truck
 
Question
I got rear axle rebuild kit from cruiseroutfitters for 94 FF
There are two sets of Koyo bearings there

2 x 70054
2 x 70052

Any idea which one is inner which one is outer ?
70052 appears to be little bigger so is that the inner one ?

:hhmm:
 
Wherever they fit! :D I'm pretty sure the outer one is the smaller one. Once you get it all apart just look at the old ones and double check.


Edit: The inner one would have to be bigger to fit on the spindle.
