Removable Rough country Long crossmember center

Hey everyone,
I thought that i would share this with everyone since i know how much i disliked my rough country long arm crossmember, especially since it wasnt a removable center section. So since my jeep is in a state of limbo with the new 4.6 stroker goin in and doig some plating on the unibody i thought it might be a good time to make that piece of crap crossmember center section removable. It isnt the hardest modification but it is time consuming. I dont know if this will work on any other rough country long arm crossmember i am doing it to my XJ and that is what the write up is based on.

What youll need:

I used 1.5x3x3/16 tubing 2x4 will also work about 25 inches
1/4 plate about a square foot
welder
drill
grinder
cut wheels
grinding wheels (sanding,flap,or hard wheel)

Here is what you will start with



The first thing you wanna do is find your preffered layout may varry depending on your set up. the piece below is cut off the original crossmember at 5 3/4 from the outside square edge. Both sides are done at this measurement. It allows you to keep the link mounts in the same place and still clear the unibody. Once you lay out 5 3/4 on each side you will be left with about 24 3/8 in between. this is what your are cutting out and replacing with the tubing.

Once you cut the ends off the crossmember at 5 3/4 you need to start to fab your new center section.
I cut the piece of 1.5x 3 tubing to 23 7/8. The reason you do this is because you need 24 3/8 but are going to be adding a 1/2 inch of material to the ends of it making it 24 3/8.

Next what you need to do is cut out the transmission mount area of the old rough country crossmember.




The reason you need to do this is the 3 inch wide tubing isnt wide enough for the xj's transmission mount, But the reason you wanna use the 3 inch is so that there is room for bolts here.

Ok so here are some updates.

-Once you cut out your end pieces where your bolt holes will go you are going to want to select a bolt and drill the appropriate sized hole. I chose 1/2 inch x 1 inch long.

Once you select your bolts and drill holes its time to mock the ends up and make sure that the tranny crossmember will line up appropriately.

Every cherokee is probably a little different but i set mine at 1.375 from the back of the original cross member to the edge of the new removable section.

I came here just to comment on how much I hate removing this crossmember to work on my transfercase or remove the front driveshaft.

That is all.
