Greetings. I have a 1998 Mitsubishi Challenger PA 4WD automatic leaf-spring model with the 2H, 4H and 4L selectable gearstick.

However my model did not come with the rear limited-slip differential (optional as a package with ABS and cruise control).

I want to fit a limited-slip rear diff from another Challenger (2000 build with rear leaf-springs) that came with this option.

Can anyone tell me whether the rear diffs are totally interchangeable?

Is this a straightforward swap, or am I going to run into complications eg different tailshaft lengths etc?

My local Mitsubishi dealer wasn't sure (they don't do a lot of Challenger work). Maybe someone knows of a Mitsubishi Service Manager I can contact who really knows his way around 4WDs, and can set me straight!

My rear diff tag shows part number M67***(can't read the other numbers) and a ratio of 4.636

Or is there a better option (eg. a Detroit locker or a read LSD from a Pajero)? Unfortunately I cannot afford ARB air lockers, so I am looking for a more cost-effective solution.

Happy to correspond directly at dgolding01@optusnet.com.au if you prefer.

I look forward to hearing from you.

Best regards,

Dave

Sorry guys, but as a newbe I am really confused.

Earlier 'Eric Experience' writes:

"Dave.
The diff do interchange without any problems, the oil is different thats all, the diff is triton, i think its the same ratio as the 2.5 diesel, the limited slip is very good in the triton, they lock well with just enough slip to allow normal stearing so in some ways they are better than an air locker. Eric"

Now 'Eric' (I assume not the same Eric) says to fit diff locks, as the optional Challenger LSD is "as usfull as tits on a bull."

So which way do I turn?

Eric, can you please find out exactly which diff locks are fitted on the Challengers in your group and let me know. Are you talking about ARB Air lockers or mechanical diff locks like Detroit lockers? I need to organise something before the end of this month as we are taking our scout group onto the sand dunes at Stockton Beach, so it is super urgent please. I can be reached at dgolding01@optusnet.com.au

HELP PLEASE!

Dave

I dont want to go agains anyone here . I am only looking at what we have experienced . We have 3 Challengers in our crew . Now every time we go hard off road , we did see the challengers struggle due to the LSD not keeping both wheels turning. Now 2 out of 3 have fitted diff locks to the rear , well actually one has both front and rear. The diffrence is awsom. Tracks that they had to get snached from every time , they now do like theres no tomorrow. They fitted ARB lockers on theres .

LSD are just that Limited Slip Differential . These are not desighned or ment to give you a lock up in the rear .

Now I dont know what off roading you do . If you just do minor tracks , you will find that a LSD might be ok . If you start to mix it on the rocks and rough stuff . You will defenently need a locker .
