Rear Sway Bar???

finally got a jeep now comes the questions.
I have looked on here and some pics show jeeps with a rear sway bar and some do not. My 97 doesnt have one (I dont know what lift and later I hope to post pics and mabey some one could tell me what lift it might be ) would this be one cause of the jeep wondering from side to side on the road?
The other question is the dropped pittman arm.
I have read that 99% of tjs do not need this, what criteria lets you know if you need it or not??
thanks for everthing.

All TJs should have a Rear Sway Bar regardless of the lift (over a couple of inches and the kit should come with extended SB links) . . . luckily a lot of the more hardcore guys are upgrading from their stock rear SB to the Currie AntiRock so you should be able to pick one up cheap. I don't think the sway bar would make the Jeep wander driving straight . . . but it could make it feel a bit unstable and all over if you have to swerve. As far as the dropped pitman arm . . . here's what I understand . . . the only time you should have one is if you also have a drop bracket on the trackbar frame mount.

Older leaf spring Jeeps got along fine without their antiswaybars but not the coil spring TJ. Leaf springs are pretty stable laterally but coil springs are not stable in any direction so an antiswaybar is key to keeping the axles under control... especially in the rear. On an extremely steep or off-camber trail, the presence of an antiswaybar could make the difference in rolling or tipping over and not rolling or tipping over.

Even John Currie was running front and rear antiswaybars in his TJ when he won the overall U.S. national (ARCA) rockcrawling championship several years ago.

Edit: Some very basic stripped down models of TJs did come without a rear antiswaybar in early years but my '97 came with one and I think all later models all included f/r antiswaybars.

Dropped Pitman arms are only installed in TJs in rare instances like on extremely tall (like 6") suspension lifts or when the upper end of the trackbar has been dropped down via a dropped upper trackbar mount. For typical lifts, a dropped Pitman arm should only be installed if there is a corresponding drop at the upper end of the trackbar which is a pretty rare thing to install. Pretty much all CJs and YJs needed dropped Pitman arms once a suspension lift was installed but they had a different geometry steering system which needed it.

I don't see one. Again, some early stripped-down basic TJs did not come with a rear antiswaybar but it's a good idea to add one, especially if you're offroading on trails that can tip or roll you over.

Yes, that confirms it did have a rear antiswaybar previously. The previous idiot owner had installed a "quick disconnect" for the rear antiswaybar which has been removed. Disconnecting the rear antiswaybar provides no benefit for offroading like disco'ing the front antiswaybar can.

thanks any suggestions on a rsb to bolt on or just find a stock one how bad does the bracket look,

feels solid but all along the inside of the frame where you can stick fingers the rust flakes off a little

should i be concerned or just drive it??

Antiswaybars don't put that much of a load on their brackets, I'd use those brackets without worry. I'd make sure they're not rusted through first though. I'd also take a wire brush to that area and then spray a little Rustoleum over it to prevent further corrosion though.
