Question from a new guy to full time 4WD.

So I am looking to buy an Grand Cherokee for off roading and have been reading up on here and have a few questions.

I think I want a 1997 or 1998 V8 (300 Torque) 5.9 (345 Torque) preferred.

But I am wondering if a 2002 to 2004 with the HO V8 (330 Torque) would work?

I also not clear on how the transfer cases in each work. I know they are 4H and 4L only. So in 4H the power only goes to front when rear loses grip? So running a front full time locker would be bad when on the street? Also is 4L the same, front only gets power when rear loses grip?

I want to add lockers to front and rear or do I need to really think about a limited slip in front in case power goes to front on dry pavement?

Thanks

Sorry for the newby questions just never had a full time 4WD system before my old CJs were manual front locking so it was not an issue.

The front doesn't have manual hubs so a spool would be a bad plan on the street unless you're going to do the manual hub conversion (which is a waste of money IMO).

You are correct, the 96+ 249 (ZJ) AWD is 10/90 split so RWD until the rear slips. LSD up front like a detroit would be great. I'm partial to ZJ's myself, the wj has a few features that make it a little harder to modify for offroad. I also like the magnum motors much better than the funny 4.7 thing they've got in the dub.

This is how 247/LSD diffs (Quadradrive) works,

https://m.youtube.com/watch?v=0PmxnShlfZI

Lockers will be great for rock crawling etc,
LSD diffs for mud, snow, gravel.

I have both, WJ and ZJ,
the WJ Are a total different animal IMO,
moding a ZJ will be Cheaper though.

So if I'm going to off road it here in Virginia a locker in rear and an LSD in front is best option if I want to keep its road manners? I was thinking small lift with 31 inch tires I don't want real big tires. I want to keep it comfortable to drive on road and enhance its off road ability. So how do you feel about a 97 or 98 V8? anything I need to consider?

ZJ V8's have a known problem with the plenum gasket, but there are fix options for that. Thats the only specific problem I can think of though there's plenty of little annoyances with either vehicle. The magnum V8 is a very solid engine and the plenum fix isn't hard to do.

This may be true on the WJ as well but you can run a 2" BB and stuff 31's pretty. There are also OME HD springs for 2.5" of lift that ride very well.

V8's of either vehicle have the d44a or d44hd in the back. It's an aluminum center section axles and doesn't have a lot of locker options. It has a stronger ring and pinion and shafts than the d35 though.

Anything else about 98s I need to know? I hope to get a 5.9 but not many out there for sale in DC area so looks like a 5.2 may be in my future.

But to be clear I can put locker in rear and LSD in front?

And what is 2" BB? I was thinking I like look of 3.5 or 4 inch lift.

You can, you also get pretty far with the factory LSD.

5.9 swap is pretty easy to if you find a 5.2 with a bad engine. The 98 has no aux trans cooler cause mopar is a bunch of fools, quick fix though. Doesn't do the key trick for putting CEL codes on the odo, but meh.

If you have a CEL, turn vehicle off then go from Off to On 3 times, on the last time leave it on and you'll see the code on the ODO display.

Sounds like a good place to start.

In my opinion, I would also look for 5.2s. There are a lot more of them and they are cheaper. Unless you want to go fast in a straight line or tow really big stuff I don't think you will notice the difference in the 5.9. Also, look for low miles, no frame rust, check for excessive rust on the spring perches and control arm mounts, make sure the transfer case linkage is not rusted out, rust on the edge of the doors, hatch, or hood are almost impossible to fix. ZJs are fun vehicles and pretty cheap to mod so they are a great choice

The trans on the 5.9 is way stronger, unless you look for a 93-85 5.2 which has the 46rh. The 44re they put behind the 5.2 in 96+ is basically the same trans as the 42re and that **** can barely handle the 4.slow.

OK so what is better an 95-98 5.2 with Quadra Trac or an 2001 -2004 4.7 with Quadra Drive for on and off road use?
