Feel "clunk" through steering column when you change from Accel to Decel or opposite

I hope that subject made sense.

When I am driving in any gear, and I get on, then off the gas, I feel a clunk through the steering column.

I have little or no play in the column. It only happens when the weight changes (from accel to decel). It happens in any gear. It happens in 2WD.

I can't see anything touching the intermediate shaft. Pitman arm looks OK.

No clunk if your stopped and turn the steering wheel side to side.

It has something to do with front Axle wrap or rotation. That is about all that changes when you switch from accel to decel and back.

It is sort of like a ball joint is bad, or perhaps a shackle bolt. But I only feel it through the steering wheel.

As dumb as this sounds, any one else have similar symptoms?

I'll crawl under it tonight and see if anything clunks.

PS. The only things I've worked on recently was installing longer brake lines, and I installed the 31" tires. I had 30's before. I assume the 31's are just amplifying the problem.

How tight is the steering shaft in-between the pitman arm and the point about 8" off the firewall (there should be a joint with a bearing that slips into a "sleeve" of sorts. If that bearing is sliding down the shaft, that the steering wheel will be loose. It'll turn fine, just will have lots of play. Could be the clunk? Outside of that...how are your driveshafts?

Well just out from under the jeep. All U-joints appear fine. Tie rods ends and pitman arm ball joint are not loose. Steering shaft has no play.

The only thing I found was the slip shaft on the front drive shaft has some play. If I try to move it up and down, I can see it "wiggle". I have no idea how much is OK.

I was wondering if I could remove the front drive shaft and drive it around to see if the clunk went away. Dumb question ... is there a slip yolk at the transfer case?

Mark.

You might give those U joints another look. Just a thought

The same thing happened to my YJ when I bought it new. I took it back to the dealer and they ended up removing the steering column and other things. It has been ten years, so I cannot remember what the problem was exactly. There were able to fix it. I had to take it to them a couple times though. They did not believe me. Because it was new, it was very slight.

Mark.

The front drive shaft is almost certainly not the problem, but you could remove it to see for sure. Really no amount of wiggle is good. At highway speeds the wiggle can cause driveline vibration and make the ride uncomfortable. I know this from experience.
