Low Speed Wobble

When at lower speeds <20, I have a wobble that feels like a roll around the longitudinal axis (body roll). As far as I can tell it is occurring on the right side but I guess it could be on the center driveline as well. Although it seems more prominent after everything is warmed up, it doesn't always happen. When it does happen while slowing down to a stop, it continues even if I put the transmission in neutral.

Any ideas what could it be or where to start looking?

Could this be caused by out of balance tires? Or should I be looking elsewhere like the u-joints?

I had a very similar situation recently... I turned out to be the steering was out of "Clock" they had to go in and put it all back into the right positions. It started out as a not very noticeable thing that turned into a huge problem... Not saying that's what your experiencing, just that it sounds very familiar to what was wrong with mine. I would check all of your steering components while you're diagnosing. Could also be as easy as worn out bushings. Good Luck!

That's interesting. Did the wobble affect your steering at all? As in did your steering wheel move along with it? Mine doesn't.

I recommend getting rotating your tires and get them balanced. How's the condition and wear on the tires?

The wets seems even across all 4. I had some cupping on one of Mt front tires (driver side if I remember correctly) but that has improved since the alignment. I have been pricing around to get them balanced.

Mud Terrains may likely be the cause at lower rolling speeds but definitely find a good shop that can handle balancing larger tires.

I have All Terrains. I'm having a hard time finding a trustworthy shop that can handle the 33x12.5 tires. The big problem for them is the 12" rim.

I'd check my tire balance. A side-to-side sounds like one tire has flat spotted and that will give you two things, a periodic roll at low speed and a tolerable vibration (high frequency, low displacement) at freeway speeds. If you have a flat spot on a tire, your into it for a new tire.

Reviving this with an update.

I got new tires on as the old ones were shot. The wobble is mostly done but still present. It is easier to feel now and it seems to be coming from the aft right. Will be taking it back to get rebalanced today and if they are perfectly balanced then I'll have them look further if possible while on the lift. Luckily, although the shop is not a 4x4 shop, half the staff are Jeepers.

So assuming it is not the tire, what else should I look at? Could a drive shaft u-joint cause that type of wobble? Or would I be possibly looking at a bent axle shaft?

From the cab it feels like if the rear tire was out of round causing it to hop like the Static Imbalance shown in the link below

Got it back from the shop yesterday. The tires were overinflated to 35psi so they dropped them to 28 and rebalanced them, etc. They did a more thorough check than I expected and found that my rear track bar is lose on the axle side which would explain some of the clunking I heard coming from the rear. I have shaken the thing on the ground and it won't budge but apparently once the suspension droops it is easy to tell.

They also found that my gearbox has some minor play and my steering stabilizer is virtually non existent. Their prices are good for parts but labor would kill me so I'll be changing the stabilizer either this weekend on next week sometime.
