So I got the transmission replaced, and I have to say, it's nice to be able to shift through the gearbox without grinding way every single gear I touch! Now for the next issue - when I drive at any speed, the whole jeep will torque to the right when I let off the gas pedal (or hit the clutch) and twist to the left to be going straight again when I step on the gas once more (or engage the clutch). It is instantaneous rather than continuous, so it will just shift a certain amount and then maintain its new heading, not continue to pull one way. At the same time as the twisting occurs, there is a loud squeak not unlike a squeaky suspension. That noise seems to come from the front end.

It has been suggested that one of the brakes may be sticking. I felt around the rotors and drums after driving and none seems significantly hotter than the other. I will continue to monitor this, though, and see if I can determine through other means if I have any faulty brake assemblies.

Another suggestion was the 4wd setup. If the front axle was partially engaging or sticking somehow, that may cause that torque. I will drive home from the office today is 4-hi to see if that changes anything. If the ride is straight, that would point fingers to that heinous vacuum CAD box, right?

Any suggestions you guys can offer are greatly appreciated!

If it were brakes I think you would feel it all the time or more during braking not acceleration. The 4x4 maybe. I would check motor mounts while your under the hood. I have had bad motor mounts give a similar feeling. Just a thought GL

Hmmm very good suggestions. I hadn't thought of those, but I'll give them a look over when I have some daylight time. Might be tomorrow afternoon if I'm lucky - I'll post back when I get those bits inspected.

I believe we are not supposed to drive a 4x4 (as opposed to an AWD vehicle) on dry pavement, in 4x4 mode, as it causes "driveline windup" and then expensive parts can go "snap!"

(The P.O. of my 1996 F-250 Heavy Duty did this, while pulling an admittedly heavy boat up a concrete ramp. He was fine until he turned, at the top of the ramp--and broke part of the transmission aluminum casing and/or trans mount--he did this TWICE, so the details escape me....)

IOW, other than when going 100% straight ahead, the wheels turn at different rates, causing the "windup" and risking the breakage.

I would not drive in 4x4, low or high range, unless there was snow, mud, or grass under the tires.

I'm sure others with more Jeep-specific experience can clarify, if I'm mistaken.

Good luck!

Y-Yess

Check the center pins, u-bolts and shackle movement on the rear axle.

Good thing I forgot to do that on my way home then! The guy I bought it from said he would exclusively drive in 4-hi...now you have me concerned. I'll do a more thorough inspection of mounting locations, shackles, and joints this evening.

I crawled under the Jeep just now (who needs food when you can work on a car instead?) and there are some things suspension-wise that just seem off. I'll take pictures and post them later when I have more time, but the greatest suspicion I have is that the shocks have a great deal of rotational play in them, particularly the ones in the rear. I haven't ever worked with a vehicle's suspension, so is that something that I should expect or should I replace those?

Also, the center bolt on the rear passenger leaf spring is quite loose. No bolt to tighten it up. I suppose that is probably not factory standard...
