New Rims, Extra wobble when hitting bumps at 55 mph
#21
Forum Tech Advisor
A speed dependent (repeatable nearly every time when a given speed is reached) wobble or shimmy is nearly always tire/wheel related (out of balance, bent, failure to move stock lug retainer clips, cupped or feathered tire wear, etc.).
Did you remove these? They absolutely must be removed to run non-stock wheels or any wheel spacer.
A random wobble/shimmy that requires a trigger to start the oscillation is rarely tire/wheel related. It is due to loose or worn parts.
There are only so many things that can be loose or warn. A systematic inspection that checks every single component in one sitting will expose the source(s) of the problem.
This isn't rocket science.
If you read my thread and watch my videos, I explain how the system works and how to diagnose the sources.
If someone has not found the source(s) of the problem, they haven't systematically inspected each and every component.

I do have new rims. I just did a torque test of 120 foot pounds and found them to be alittle lose. I also changed out the front tie rods out from the OEM's to the extra rear OEMs on the front. I am going to get it on the lift friday so I will check it out. Great write up. I will check back tomorrow if the tie rods and torquen' the wheels made a difference.
Thanks JK brothers!

The torque spec for your front trackbar and lower control arms is 125 ft lbs.
You don't have any suspension component or wheel lug with a 120 ft lbs torque spec.
You have one tie rod that connects the 2 knuckles. Are you referring to the swaybar links?

The torque spec for your wheel lug nuts is 95-100 ft lbs. If you torqued them to 120 ft lbs, you may have over stretched them.

"Are you referring to the swaybar links?" Yes
The torque of 120 was from the guy that install the rims. Also on the MB72 rims there is a couter bore to allow for those star washers.
I am going to replace the pittman arm bolts today at lunch.

The pitman arm doesn't have any bolts.
120 ft lbs on the lug nuts is too much for a JK.
Do you happen to have a picture that shows the wheels have a factory counter bore on your aftermarket wheels? This would be a first.

Here is the closest I could find with out taking the rim off.

You see the the counterbore on this rim is very close to the the MB 72's

If you have yet to take it back to whoever put the tires on the rims and balanced them... you should. If you tell them that one of your wheels is giving a bad vibration they should be eager to at least check it out for balance. all DW starts somewhere.
