Hah, I once drove it unsupported like that, several years ago when I didn't know what the hell I was doing. Realized something was up when I started losing gears. That was 2 trannys ago, but that trans lasted another 2 years.

Ok, so let's say you did drive it.... About 4 different times over 4 weeks, before someone finally explains what the hell you've done!
I took mine off to have it sand blasted and painted, and things got busy, I didn't know better and now I'm freaking out!! I put a jack under it tonight it went like 3 inches maybe more. I get the skid plate back tomorrow. Do you think I've damage anything?

Nothing sounds wrong, it shifts fine, I've not heard anything unusual yet. How can I check to make sure nothing is wrong??


I'm just sick over this! Can't believe it!!!

There was a post a while back from a guy who drove hundreds of miles without it supported. Is it a good thing? No. Is it the end of the world? No.

Run it till it breaks. Change the fluid to check for shavings but otherwise not much you can do.

Personally I'd worry a lot more about the motor mounts and exhaust hangers and the stress they were under holding everything up rather than any internal damage. The internals of the engine, transmission and TC are pretty locked together. The whole unit may move changing driveshaft angles, but internally stuff will stay relatively at the same relationship.

Thanks fellas, I've read a hundred posts on this, and starting to get worried even more. So even just a little positive reinforcement makes me feel a little better.

I agree, but with Sjones manual trans the gearshift lever probably was hitting the tub and putting pressure on it. Probably wore out his synchros.

It's not good, but if you drove it like a sane old person you could have caused zero damage.

Lol, well then for the most part I did drive like a sane old person. So hopefully I'm good. I crawled under and looked around today, motor mounts seem ok, not sure exactly what I'm looking for, but nothing was cracked or broke. However, I did notice that some of the shift linkage appears to b bent. But it did not seem to affect my shifting. I'll have to check into more once I get things back in place.

I assume that I can replace those pieces that are bent? Without too much expense?

Yup, i would only be worried about the motor mounts as they're somewhat "the hardest" thing to fix resulting from skidless driving. Everything else should be just fine. Check your fan shroud for possible damage.

I'm going to assume the linkage you are referring to is actually the transfercase linkage. (2h,4h,4L) you might have an issue shifting into 4wd if this is the case.

I never priced out the linkage, can't be to much i'd imagine.

If mine was bent i'd replace it with a Novak cable shifter, it's a good upgrade.

Check the catalytic converter hanger mount by the transfer case to see if its been a detached mount or damaged (separated) by running the transfer case skid plate dropped... IMO

I was helping a buddy yank some parts off an XJ in the junkyard one day. I don't remember what parts. In the junkyard they cut the cats off, so there is nothing extra helping to support the drivetrain when the trans mount is removed. We pulled off the trans mount & trans crossmember/skid to get to whatever we needed. We didn't have anything supporting the trans, so as we did that, the engine/trans/t-case tilted until the output shaft on the t-case was pointed toward the dirt, and the limiting factor became the valve cover of the 4.0L hitting the firewall. We wrestled with it for a while, but we needed another few inches. We kicked the t-case a few times and the valve cover bent the firewall, the motor mounts snapped and the whole assembly dropped. Scared the crap out of us.

Seeing what an unsupported engine/trans/tcase does in a junkyard, it really makes me wonder how people are able to drive around without the t-case skid in place. I can only imagine how much stress is on the motor mounts, the exhaust and the copious amounts of output shaft movement there must be. Just be glad your drivetrain isn't laying on the ground someplace like that junkyard XJ was and move on.
