if theres locks on the hubs or a swich and air chuck for an air locker....and go check it out, although most is, not all things that sound too good to be true are

I hope for you it is a D44 front as it would be a steel, don't bother with a lottery ticket for a while as this will have used up your allocation of GREAT luck! You would need to get brackets welded as the rear of the Grand is a coil 4 link set up and your cherokee is leaf. The Grand D44 center is aluminum and not really favored, you would be cheeper getting a D44 metric ton out of an old XJ preffered or MJ and changing the leaf spring mounts to the top. I've been looking for a D44 RS/ high pinion out of any Ford 73-77 F100/ F150 and haven't seen any at the junkyards, at the dismantlers they want 500+ and I would still have to cut it down and get shafts, locker and regear.

Here is a link to help id the axles by looking at the diff cover

If it has a Track Lock, Aussie, Detroit, a spool or welded carrier they are not selectable, and if you spin one hub the other should turn the same direction, may take a few turns for it to lock

If it's a selectable it will have an air line, electrical conection, or cable depending on which type to lock it and you would neet the switch/cable for install.

If the hubs counter rotate you have an open carrier- no locker or worn clutches in a traclock/ limited slip

x2 you still dont have your information correct. do you know what a d44 looks like?

the guys lying to you

Yeah its got detroit lockers. He probably is but it doesn't hurt to check it out.

Ok so I just called him and he told me he talked to his son and found out they are actually the stock dana 35 and 30 but that his son put 41 spline chromoly shafts and they do have lockers. He also put bigger "expensive" hubs on the front. Is it still a good deal?

41 spline???? I say BS.. I dont know of any company that makes a 41 spline shaft for either of those axles. The only 41 spline shafts I know of are super custom and for 9" axles and are gun drilled.

LOL he has no clue what he is talking about. there is no such thing as 41 spline d30 or d35 shafts. no its not a good deal. went from d44 to d30 and 35..... this story keeps getting better and better.

seriously dude. do your homework. its a simple search and you could answer your own questions!

AKA. like I said before bull****. run far far away from this "Deal" if the guy doesn't even know whats on it himself then you have no idea what you're getting into. not to mention a D35 even with a super35 kit still doesn't solve the problem of the tiny ring&pinion. Also to be considered is the fact that under not-so-demanding conditions the axel housing likes to bend and then Chromoly's or not you're gonna have serious problems.

x2 This guy is either dumb as hell or trying to pull a quick one on you.

With you being new to axles, and this guy trying to sell axles, If i were you i would simply walk away. $400 is what a stock rear Dana 44 is going for, if you have that much money right now, start looking for someone selling one.

The rear axle in a grand cherokee is NOT bolt in ready for a XJ. while $400 seemed like a possibly good deal, none of it made sense so dont get stuck with $400 of scrap metel.

on top of all that grand cherokees are wider so youll need to get a different offset rim so your cherokee wont look totally stupid..

41 spline axles? seriously? chromoly?

i bet they are just stock differentials and the guy is trying to get you. well now just say thanks but no thanks and walk away. its in your best intrests man

If you where closer and had a lil more of a budget I would sell you my XJ d44 that is all ready converted to disc brakes. Still would need to be regeared.. but I know someone who does that too

False. the dana 30s are the same width from XJ to ZJ to WJ to TJ YJ all of them are the same width.
