XJ Cherokee axles will work, but you'll have to cut and reweld the perches on the rear. The front will bolt right in. You can also use the front drive shafts. Rear drive shafts are Comanche specific or will have to be custom built.
Grand Cherokees aren't really great for drivetrain parts. Although ZJ models (93-98) front axles will bolt in but it's a low pinion setup. I think the transfer case can be swapped also. NP231 or 242
Been running 15/40 in all my 4.0 engines for years, mostly for the zinc count ( whole other topic). It doesn't get that cold around here in South Central Pa, but maybe for a week or 2 during the winter.
Not a Comanche but my wife's 2004 WJ, 4.0 190k miles 15/40 oil
Seems like it has a dry start issue, it's taps and rattles for around 2-4 seconds on startup untill the oil pressure comes up. Is their anything you guys recommend I can add to the oil or anything like that to cure this?
I don't have this issue with the trucks or the XJ.
Yep seems like model year 2000 all the auto makers began going downhill..... everyone has opinons, but I am really not impressed by new vehicles at all, I'm a hammer and wrench kinda guy, not so much modules and programming...
Who else wakes their trucks up each spring from in their garages and or under their covers?
I've had this truck almost 10 years, and it still brings a smile to my face when I get to go zip around in it each year when the weather gets nice.
With 3" or so of lift your driveshaft should be fine to use with no modifications. I'm sure the Trac lok packs are shot inside so if having Limited slip is something you want, I'd go ahead and redo the clutches before you install the axle. Watch the brake lines and maybe even replace them all on the D44. Otherwise is a straight bolt in process.
