I have a couple random questions for you gues. Im guessing I have a d44 rearend see pics. I have a 96 limited 5.2. I have a almost humming noise when on freeway is ir normal or heck no. Im not used to the alltime 4wd. and what gearoil should I be putting in front and rear. and I took a pic of a tag on the rear and it has numbers then a LS could that mean Limited slip? Sorry for the newbi questions

 

that is a dana 44a. the humming could be a bunch of things. where is it coming from?

 

LS= limited slip. make sure to add a bottle of friction modifier to the diff oil when you change it. 85-90 gear oil is what you want.

 

sound like its coming from front drivers side but only at higher speeds. Would I use same oil in the front also? and I know my xj had a trac loc locker is it the same in this one?

 

Same oil, but no friction modifier is needed in the front axle. Check the ujoints in the front driveshaft and look at the hub bearings, those could be the cause of the noise.

 

Thanks man. It should only be like what 3 bottles? How much additive do i put in?

 

Like 2-3 bottles per diff depending on how much you spill, front can be kinda tricky

 

Buy a gallon and a pump.
