Back end stepping out
 
Back end stepping out We (my family and I) are currently looking to buy a "new" jeep and just got back from test driving a 2000 TJ Sahara. The TJ has just over 100,000 miles with a 2.5" lift, 33" km2s, and a few other small modifications. The problem we noticed with it is that when you step on the gas going 25+mph there is a obvious jerk from the back end to the left and then when letting off the gas it has the same jerk but to the right.

The owner said it has has this problem for years and they looked into many things and could never find the fix, they just got used to it. So, I was wondering if you all had any similar experiences or ideas about what the problem could be.

Welcome! 100,000 miles is fine on a jeep, they tend to go 200,000+ with proper maintenance. First, a 2.5" is darn small for 33" tires. If you are planning to 4wheel with it you will need either a larger lift or highline fenders. The shifting during acceleration and deceleration could be something wrong with the rear differential or maybe track bar. Either way I would have a trusted mechanic, preferably one that works on jeeps, check it out before you buy.

Run away or find out with absolute certainty what needs to be fixed and use that to negotiate a lower price. It should absolutely not be doing that.

I was told that it was my lockers that did that. ?? No??

Mine does the same thing since I put a locker in and all control arms and track bars are new., still havnt got used to it and I'm a little heavy on the gas so that's no help.

What kind of locker? I don't see how accelerating in a straight line would cause a locker to lurch one wheel faster than the other. I understand around corners if an autolocker engages, but not going straight...

Agreed.

A Detroit would disengage, but that's neither here nor there.

My vote is for blown bushings on one or more control arms, brake rub, or issue with the diff. Doesn't seem like PO was too concerned with maintenance if he just said, "F*** it, it drives like shit but I'm not going to fix it" and then proceeded to put off-road tires with no siping on a jeep with obvious potential loss of traction issues he only drove on the road.

He actually looked into a lot of things to try to fix the problem, but I don't think he ever thought it could be a suspension problem. Also I doubt it's the brakes, because in the past week it's been in and out of the shop getting those fixed.

My vote is for track bar or CA bushings.

This seems to be the general consensus.

We just closed the deal on it and will probably get it checked out on Saturday by our local off road shop.

Mine did the same exact thing going down highway a few weeks ago about 5 miles from my house. Of course I keep getting on and off the gas trying to figure out what the new symptom was. Snapped off the mount for the lower driver rear control arm.
I would look at control arms and mounts.
