When i took the bolts out of the skid plate ,the whole driveline fell down.this cant be normal is it? I was wanting to clean my trans and tf case any help apprciate:confused:
 
Yep thats normal.
 
The skid plate also acts as a cross member holding up the TCase and tranny.
 
i need one of these crossmembers. where can i find one. all the junkyards have crushed the jeeps around here
 
that must have been a thrill!:eek:
Put a jack under the bell housing to keep the tail end from dropping. Did you tear the motor mounts??

I don't like the OEM skid-plates/cross-members. I built my own. Can you weld? (me neither, but I wish I would start). I had a friend help me build mine.

It's as simple as angle iron bolted to each frame rail and a bar welded between the two. I cut off the extra metal from the angle iron.

I never did understand why the Jeeps always used one Tranny mount and a doughnut gasket to hold up the drive-train. I used 2 tranny mounts to build mine.
 
good looking fab job. I will admit to it being a cross member but not a skid plate.:D
what problem do you have with the stock skid plate??
The only problem I have with it is it fills up with mud and junk and is a PITA to clean out. I don't see you having this kind of problem in your hood.:cool:

The problem I had with the skid plate was it was cracking and about to break. The PO cut it (I guess to install the T18). Now that is was smaller it started to crack bad.
No it is not a skid plate. With 36 inch tires on a CJ5 I never have a problem with scraping my belly. If I ever get around to stretching the wheelbase (pipe dream) I will add plates to the cross-member.
 
ohhh, i like that crossmember. do you have any dimentions, or plans?
 
Jamie, I didn't have any plans but I first removed the OEM tranny mounts. It was made with a donut on one side and a Tranny mount on the other. Instead I bought 2 tranny mounts like this:

These tranny mounts are very common and I found them at a local auto parts store.
The adapter plate between the Tranny and TCase has 2 bolt holes but the tranny mount is too wide to fit in there so I had to space the mounts down with a bar. I also used a piece of angle iron because the tranny mounts extend further out than the adapter plate. At this point I had 2 tranny mounts under my tranny with the polyurethane side pointing down. You can see the angle iron in front of the tranny mounts.
Now I bolted 2 pieces of angle iron to each frame rail. In the side view above you can see I cut the leading and trailing edge of the angle iron but don't worry about that yet. I cut that last.
Next I took a piece of channel iron and cut it to fit between each angle iron. I also drilled holes to match up with the tranny mounts.
Next step I bolted this channel iron to the tranny mounts.
Then I had a friend weld the channel iron to the angle iron on each frame rail.
Now (as i mentioned above) I trimmed up the angle iron. It extended down further than necessary plus I angled the leading and trailing edges.
Now paint it.
