Wj To Mj Mods

[Oddmodman]

I've searched through all the DIY pages for upgrades from Grand Cherokees. I only found two, upper control arms and the dual brake booster, and I thought there were more. Does anyone have a list of what parts to strip from a WJ if you get ahold of a parts vehicle? Or perhaps links atleast?

The front seats should bolt to our existing seat tracks if you have buckets ( manual seats )

The center console lid with some mods

 

That's all I can think of currently except the brake upgrade

Besides the wj the v8 zj grand cherokee provides us with tie rods, draglink, pitman arm with provides a 1" drop, sway bar, sway bar end links, and if I'm not mistaken the steering box and maybe ball joints?

I didn't even remember that there were two designations of Grand Cherokees. What's the difference? Also, that basically sounds like the entire front steering assembly eh? Lol.

Door Weatherstripping - thicker. Some say itmay be too thick. i'll post a comment after I try it on my 91. Also, later model XJ weatherstripping.

Cool. Can anyone tell me the difference between the two Grand Cherokee designations?

The ZJ is the 93-98 Grand Cherokee, 99-04 is the Wj.

Yes the ZJ (93-98) is the older boxy look (kinda like the XJ) the WJ (99-04) is more rounded and is slightly wider.

[Oddmodman]

Any parts that should be taken from one and not the other, or are all the guts and everything the same besides the body?

The ZJ has the same front axle as the MJ, XJ, and TJ but is low pinion. The V8 tie rod is an upgrade, and the V8 sway bar is also an upgrade. There are differences in the engine mounting so stuff like that may need to be researched bfore digging to far into them. The wheels can be swapped on if you like them as well. Some people have swapped in ZJ seats, though I personally don't care for the style 

 

The WJ you can use the front brakes with some modifications, and the booster/MC with minor mods. Also the upper and lower front control arms, also with minor mods. If you switch to the front brakes the steering can then be used also if shortened. I'm not sure about the seats that were mentioned. 

 

Here are some great threads on naxja for junkyard upgrades...

Sweet thanks! I didn't realize you could use both sets of arms. Right on. As for the seats, I prefer my bench anyway.

I am fitting the front seats and both axles & steering from an old WJ to my MJ. Plan  to chop the mounts from the rear 44 & truss it. Not the strongest axle I know but they were free, plus are 3.91 gears & varilocs, cheap way to disks all round & better brakes & steering setup. Mine is going no higher than 3" so the low pinion front axle won't be much of an issue
