|Rob_Feature||For anyone who happens across this, I found out I had a busted motor mount on the passenger side, which is super common!|

Excellent info and ideas here everyone. FYI, my body mounts ARE as rusted as everyone says, so I'm going to avoid those for as long as possible
When driving this weekend, I noticed something that tells me the problem lies in a motor or transmission mount somewhere. It's tough to explain, but I'll give it a try. If you get what I'm saying let me know what you think.
So far there are 2 thoughts here: 1. The body could be shifting or 2. the motor or t-case could be shifting. I'm 99% sure it's #2 and not #1...here's why:
When I corner to the left, I can feel the shifter slide to the right. If it were the body shifting, as was a possibility, the body should shift to the right, thereby making the shifter feel like it was sliding LEFT (because the motor/trans would be staying put, with the body shifting over it to the right).
Unless I'm mis-thinking...this says for sure it's something underneath that's loose. A neighbor of mine (a Jeep guy who knows way more than me) agreed with what was said about the motor mounts here. He suggested getting under there with a crowbar and moving stuff around to see what's loose.
So, that'll be my next course of action...my only fear is breaking something...so hopefully I'm not so gentle that I get nothing to move. Anyway, I'll report back...thanks for the great direction so far...

These nuts are welded, & can rip loose from that weld. Now you have a nut that is freely spinning inside the framework of the tub.
To help prevent this, there is a trick. You drill a small 3/16" hole just above the nut, then use PB Fabulous Blaster with the spray straw to soak the nuts for a few days before trying to loosen the bolts.
If the nuts do come loose, the only fix is to chop a much larger hole above the nut & re-weld it.

|Pylonpounder||All I have for you, as a semi-newbie myself, is a word of caution; Those body mounts, especially this old, will probably be one of the most irritating fixes you do. It's not difficult (Unless you twist a head off one of them like I did) but they are usually rusted in there pretty damn well, and can, as I discovered, just break when trying to take them out.|

I had a Ford Ranger that had a bad motor mount and when taking off and turning the motor would lift with the torque and the shifter would move all over. Don't worry I don't thinks it's anything major. Just spend some time on your back with a flashlight and push/pull/poke and pry on your Jeep. You will find the issue soon i'm sure.

Just to clarify, the 'body mounts' are the bolts that fasten the body to the frame, correct? I guess I can't see how, if all those were in place, the whole thing could be moving...what should I be checking for when I look at those? Damaged/old bushings that could allow a little play back and forth?
This forum rocks for a newbie like me...thanks for all the great support and mentoring here!

[quote=Rob_Feature;400095]Ok, just a follow up here..... Also, when driving, on many corners I don't feel anything (ie. it feels solid) but on more extreme corners (more centripetal force) I can feel it shifting...so I'm not sure the whole thing is moving.../quote]

You might try gently prying between the trans & skid plate. If the mount between them is bad, you should be able to tell pretty easily. I use a 3' crowbar to check such things, just be careful not to force it so much that you break the mounting bushing.
Do check the engine mounts & body bushings as well

Yeah, I checked the bolts from transmission box to skidplate...they're solid (although the one with the rubber gasket needs a new gasket, but I can't imagine this is the problem).
It's a 5spd and yeah, the shifter moves on the corners...sound familiar to you 4Jeepn or anyone else of a known problem?

|4Jeepn||Have you checked the bolts yet? Was this a auto or 5spd, does the shift move in the corners?|

Ok, just a follow up here. After posting my original question I drove it a bit and crawled underneath to see the situation.
From what I can see, it doesn't appear to be missing any connections...so I'm not totally sure the whole thing is sliding. Also, when driving, on many corners I don't feel anything (ie. it feels solid) but on more extreme corners (more centripetal force) I can feel it shifting...so I'm not sure the whole thing is moving...
Is it possible that there's parts inside the case that are moving and the whole thing isn't? I'm not confident enough to take a whole ton of stuff apart so I want to see where I should target my effort. I'm thinking taking off the skidplate and (with my hands) trying to move the t-case to see if it's loose is the first step. Agreed? Any other input?
Thanks Jeepin_Chuck (and anyone else who can pitch in)

Very very new to auto repair and maintenence here...just getting my hands dirty on this YJ for the first time, so please make any explanations as basic as possible.
In my 93' YJ when cornering, I can feel my transmission sliding to the right or left through the shifter. Is my assumption correct that most likely some bolts have come loose and it truly is sliding around on top of the skid plate?
If so, I obviously need to do something about it...can you give some advice on a step by step procedure to check out the problem? If it is totally loose, will removing the skidplate drop the transmission on the ground or is there something else holding it up?
Any help and advice on how to proceed would be super appreciated. Thanks!
