Nico had this problem, he replaced the skid. What i would do is take the skid off and bang the crap out of it (just on that spot) with the biggest hammer you have in the garage or cut it.

that stock tranny/engine skid doesnt work with a lifted jeep
your transfer case skid is just fine but the engine skid needs to be replaced with an after market skid
you can run without it

if you have to make that work you need to cut the one side off and weld a new brace that runs a differnt wy to clear the drive shaft

Tripp, have you looked at that brace, hitting it with a hammer will be a waste of energy.

One thing you can do is take off the engine skid and saw off that side and then put a small bump stop on the plate to keep it from rattling on your engine.

Or you can do what we have been doing around here and fabbing up a piece to weld onto the plate that creates a cross member that goes up and over the drive shaft.

Hope that helps.

On the ones we have fabbed up they go about 6-7 inches up, over about 4 inches and then back down.

We have used a half of a 4 inch pipe at the top to give a little bit more clearence. Let me see if i can find some pictures of the one i have.

you cant notch it I tried that on min I couldnt notch it enough to give me the room for the drive shaft when I would flex

you have to cut it off completly and weld it up to go over the drive shaft

I removed mine and have been wheelin with out that skid I have the steel to make one but I have been to lazy to start it

Not a bit, and we have beat the crap out of a few of them, they are holding strong. The one thing we learned was to gusset the corners and it will make it bullet proof.

The good thing is that the full crossmember is still intact.

I have see a few plates with that section cut out and they run just fine, untill it shovels itself in mud or on a rock. But it does hold up to a fair amount of abuse.

When did the TJ go with that style skidplate? 2003? It seems crazy that Jeep would go to something like that, it seems like they should have known it would create all kinds of problems for offroading. All I hear about that newer skidplate design are complaints!

You may be right on the 03. Mine is an 03 and has / had the issue, and I have two buddies that have 05's and they had the same issue.

It is a very poor design.

By the picture above, you can see how the driveshaft will hit the crossmember in any kind of flex.

its just an add on skid theres 4 bolts holding it up and you dont realy need it its kinda like the engine skids you buy after market
I think they started to put them in in 03

they dont hold up to abuse very well

Isnt that only a cover on front? From what I remember on another thread, This was an addition to the skid that holds the tranny.

I agree, that's why I thought it occurred in 2003.
