FZJ80 locker in a FJ60???

[88chevota]

I have looked around but I can't find anything. I am wondering what is involved in the process in putting a FZJ80 electric locked rear diff in a FJ60 housing. I am pretty sure it has been done before, but I wonder how complicated it is???

Anyone know???

The FZJ80 can go into the axle if the axle is a full floater. No provision for semi-floating axles. To make it work you need to have longer than normal splines cut/rolled into the axle shaft (it is on the drivers side if used in the front and Bobby Long makes them for FJ40-may have 60's too). You will have to notch the axle housing a bit for the lock mechanism to operate. I'm not sure about the 60 driveshaft flange to 80 pinion flange either.

It is a drop in affair with a few provisions.

why will it not work in a semi float? I would like to put it in the rear, but I also have a cruiser mini, hybrid rear axle so i have no C clips. are there any threads on this????

 

[Bret]

There are several. There is no way to run c-clips, so if you had a alternate way to hold the axle in you should be OK. The rear FZJ80 bolts right up to the FJ40/60 axle no sweat (a little clearancing) You would have to find a long spline solution with whatever axle you run though. The locking mechanism slides along the axleshaft to engage and disengage. Do a google on FZJ80 and between google and MUD it should answer your questions.

sweet!!! so what do you think is a better set-up toyota e-locker or ARB??? i think I can pick up and toyota third cheaper than an ARB and faster install time. then sell what I have.

For my personal preference would be the ARB. Tried and true, locks/unlocks instantly, simple switch on the dash.

Here are my opinions on pro's/cons
For shear simplicity the e-locker with a cable
For instant response - the ARB
-e-locker is friggin heavy. Lifting it into place was more difficult than the ARB (no big deal)
-if you use the electronics with the e-locker more parts to potentially fail, but if it fails you can manually lock and unlock the diff (it would be a pain in the arse but you can do it)
-the e-locker does not engage/disengage instanly with either the control box or cable (I have the cable)
-running the cable into the cab is kinda a pain for the e-locker if you go that route
-motor housing may not like to be immersed in water (if you use it). Things have a tendency to fail at the worst times.
-with the electric there is no need for the air line and compressor- you will still need to run a cable or wire though.
-don't take the axle out while the diff is unlocked or don't break the long spline side axle with it unlocked. It can be a bear to get it locked again to be able to remove the diff from the axle.

I'm sure there are hundreds more
