Body sway when shifting???

I have a TJ wrangler and whenever i shift into 4th or 5th gear the body sways either left or right depending on if im pushing the clutch in or letting it out. It feels like its being caused from the torque but im not sure can anybody help me fix this????

My 98 had the same problem in all gears. I found that my trans mount had split and was allowing everything to shift whenever torque was applied or removed.

Did you ever find the route of our problem? This has been happening to me. I kept thinking it was a rear sway bar issue, but couldnt see anything.

Check the trans mount, the rear sway and trackbar and the control arms.

^ This.
Plus, I would bet that you get somewhat of a bump during your shift and maybe even going over bumps.

Unfortuantely I wont get a chance to look at it until this weekend... I dont get any bumps during shifting, and the trans seems fine. Its in all gears that I feel the body sway. It moves when accelerating, then when the clutch is depressed and the body goes back, then again when the gear is engaged. I wonder if its the transfer case...? i recall when installing the transfer case lowering kit, it was tough to realign the bolts to get it back on (not sure what would cause that).
*I also checked (from what i can see without lifting it) the rear sway bar, tackbar, and trackbar relocation bracket look ok

Did you install the drop pitman arm that came with your lift?

Have you checked the control arms for proper torque on the bolts/nuts? I also recommend checking the control arm mount bolt holes for any elongation, a wallowed out mount will allow the rear axle to shift...

Sorry for just getting back now on this, but i ended up having to replace the rear U joints. The sway is gone now

Glad you fixed it, but for future references, when I swapped my D35 to a D44 last weekend the rear trackbar mount that came with my lift kit had 2 bolts loose giving it lots of play. I swapped the bracket to the 44 and drilled the third hole out thats on the top of the bracket and added the third bolt, and put locktight and lockwashers on the other bolts. Took the sway out. Mine did it when shifting from first through third though.

Still good to know. I bought a JKS adjustable rear trackbar and angled relocation bracket - thinking that was the issue. I still plan on installing it, as well as a stabilizer kit for the front to help clear up a little w.o.d. issue

ok, so back to this whole issue again. The sway is back, in addition to knocking when shifting (at times), and now an annoying squeaking noise underneath that seems to be amplified when turning left and right when driving...

Track bar brackets, bushings, bolts,...
Control arm brackets, bushings, bolts,...

Something is loose back there that is letting the acceleration/deceleration shift the axle.

Keep in mind that free advice can frequently be worth less than you pay for it.
