Liberty KJ Steel IFS diff

[Backwoods Rambler]

So that's not just a diesel front end?

 

[tommudd]

No not a diesel front diff
All KJs came with a D30a
this one is a custom made one available only from JeepinbyAl
Should be a lot stronger than the aluminum D30a

Yes, Mine has an RD100 ARB air locker. You could possibly put an Eaton electric locker in there as well. Wouldn't recommend a non-selectable locker.

i guess i'm not seeing where the driver's side axle locates into the housing...

but then again- i have a real jeep with a sfa and i know where my shaft goes j/k

There are a total of 7 axle sections and 4 CV joints.

The diff sits on the drivers side. The three axle sections are connected by CV's and insert directly into the pumpkin on this (short) side, no axle tube. The passenger (long) side has 4 sections, 3 as described for the drivers side plus an intermediate axle shaft in the axle tube.

See I know where my shaft goes too.:sombrero:

What about the one in the rear? :Wow1:


:coffeedrink:Couldn't help it....

Thats a nice chunk! Low pinion 30's have a problem with forcing the pinion away from the ring gear. An aluminum center section can't help but with any Dana 30 an aftermarket super stiff diff cover helps limit the flex. It looks your 30 has some kind of ring around the opening to the chunk. What is that? My wife drives a 03 Liberty Renegade and loves it.

It looks your 30 has some kind of ring around the opening to the chunk. What is that?

I noticed that also. I'm guessing it is an attempt to stiffen the marginally stiff differential housing itself. There is a theory that R&P failures in the Dana 30 are due to the housing flexing and the shaft(s) flexing and as a result end in major b0rkage.

If you attempt this with a SFA Dana 30, think about the differential cover to tie rod clearance. An easy approach might be to get one of those massively over built differential covers that are out there. Or fab something yourself.

Its the mounting flange, looks to be around 3/8 steel ring with three ears. The IFS diff is rigidly mounted to the crossmember with the three ears. The diff cover bolts through that bracket to the pumpkin.

Plenty stiff

sounds complicated... guess it's good that there are smarter people than me out there to fix this type of thing on a trail repair.

btw- nice shots of it on the trails... especially the shot of you going down the rock ledge.

or just get some D44's under it.:sombrero::elkgrin:

Not that hard to pull a CV on the trail, doesn't take long at all. Sounds more complicated than it is really. Pretty simple setup really.

Sweet!
