Stock '89 XJ D30 Question

8T9XJ2DR · May 10, 2009

Need some input as i'm horribly unfarmiliar with differentials - changing all the fluids on my completely stock '89 Jeep Cherokee 4.0L 5 Spd. I have to turn the rear wheels(if both spin the same way it's trac-lok) to see if I need friction modifier for the rear(D35). Do I need to do the same for the front D30? I've searched and searched and can't seem to find it with my limited knowledge in this area. From what simple understanding I have my assumption is they couldn't be optioned with trac-lok on the front. Thank you for your help.

No LSD in any D30 from the factory.

Thank you joe_peters

Looks like an open rear diff too. One more thing down on the maintenance list!

Amsoil severegear ftw! With this you wouldnt need an additive if you had an LSD.
