WJ LCAs on MJs/XJs

[AMCJeepMJ]

So, I read on a thread recently [and now can't find it] that WJ [99-04 Grand Cherokee] lower control arms will work for a mild lift to keep the front axle where it is supposed to be instead of having it come back towards the cab.

 

After a little research, I found the WJ LCAs appear significantly different than MJ/XJ LCAs:

 

MJ/XJ:

 

WJ:

 

 

Which leads me to ask if anyone can confirm:

1: If this is indeed the correct part

2: What amount of lift the WJ LCA is good for to keep the axle centered [2"? 4"?]

3: If there are any fitment issues or anticipated complications during installation due to different designs

4: If the oval bushing will cause any performance or clearance issues of the control arm vs a round bushing

 

I know these are a lot of Q's, but money's tight for Jeep modifications these days! The WJ LCAs would be for a DD rig with light offroading, intended 3" front lift, and 30" tires. I am still in the parts collecting phase in preparation of the front lift.

WJ arms are the same length as MJ arms and should work up to 3" of lift.

 

to run them you just need to trim the steel bushings a bit and I trimmed the bracket on the axle a bit too to get maximum flex.

 

they provide much better on-road handling while still working very good offroad.

 

The biggest benefit is that the bend provides for tire clearance while turning. :thumbsup:

Ahh, I see. It took a little modification for it to work. Nice to have pics, too!

 

I'm glad I asked since I didn't see it as a direct swap without a bit of playing with it.

so just trim the axle part where it LCA would touch. should i use a coarse metal file or an angle grinder?

The bushings too- notice the pic shows them side by side, both trimmed and untrimmed.

now i notice what was trimmed on the top two pics :doh:

 

mostly asking if i should use a file or grinder, don't want to take off too much

[Pete M]

angle grinder works great. it's hard to screw up. :thumbsup: just don't let the rubber bushing roast.

i put a set on my mj and my gf's zj.i think for what i paid for them they're worth it.

I used a chop saw with a metal blade for the bushings, and a sawzall for the axle brackets.

 

I don't like angle grinders because I'm more prone to "oops" with one.

 

And, the ride difference is definitely noticeable. I think this is a first rate mod.

I did the exact same swap a couple months ago

They werent that bad to install,the bushings had to be trimmed

I used a sawzall with a metal blade and a razor knife

They sit nice

I painted mine red before installation

Whatever you use to cut the bushing shafts, dip them in cold water while in progress to prevent the rubber from cooking. :cheers:

 

 

Jeesh Pete, even your hammer handle has rust. :D

[Pete M]

it's everywhere man. :ack: even the plastic rusts here.
