Hi guys, just been informed I have a dana 30 front diff and a dana m44 rear are the lsd's? I ask so I can put the right oils etc in.

 

you have a D30 in front and im pretty sure that with the 4.0 you have a D35 in the rear

 

agreed 35 in rear ,,Chrysler/mopar calls that you ad an aditive with your gear oil unless you go with a full synthetic witch is better in the long run

 

grand cherokee guys...

it is either an Aluminum dana 44 or dana 35. both use the same oil. LSD or not depends if it came equipped with one..

 

Yep Jeep UK say d44m in the rear but they were chucking their dummy (pacifier?) over the front diff saying they think it was a d30 but I should put addative in both as they were not sure. I agree about the oil my mk1 orvis only has an lsd, trak-loc - whatever you want to call it in the back end and I have the fully synthetic stuff in. Ours comes in litres which is £25 a bottle circa $30-32 a piece, what do you guys pay? Don't worry explainiing pints and quarts, some of us over here still understand decent imperial measures - we don't all love europe.
