Hey everyone,

I'm running a Teraflex leveling kit (pucks) on my 2012 Sahara JKU, along with 31.5 Muteki Trailhog tires @ 30 PSI. However, the Jeep sways really bad. I'm going on a roadtrip next month and I really don't want to drive 5 hours with it like that???

Any advice? - I've attached the alignment sheet. The guys at the shop said that some parts cannot be adjusted

 

Not exactly sure what you mean by swaying. I associate most things I would consider as swaying as being shock related.

How many miles?

Swaying associated with bumps, especially at low speeds off camber? Check your shocks factory shocks are trash and wear out super quickly: my Rubi shocks were cooked before I hit 30,000 miles.

Swaying like taking corners like and old boat? Lots of body role? Check the sway bar links and again shocks.

Swaying as in loose steering? Check all steering components for worn rod ends and bushings. There are several videos and how-to's on YouTube. Also check ball joints and wheel bearings, also numerous videos on YouTube. If all the steering and front end components check good look at the steering box itself, these don't hold up well to large tires and excessive mileage.

Happy Jeeping.

 

We could use a better description of what you are actually feeling. A top-heavy body roll? Wandering / loose / flighty steering? Steering jerks to one side when you hit a bump? Something else?

Correct. Without adding components, 'Caster' and 'Camber' can not be adjusted.
'Toe' can be adjusted, but likely did not change due to the 2" pucks being installed.
The steering wheel can be centered, but is generally done during the lift install.

What jumps out from the alignment sheet is the Caster. Stock is around 4.2 degrees, you are currently just over 3 degrees. As that number goes down, the steering gets progressively more flighty/floaty/wanders/pick your verb here. Is this what you mean by by 'Sways really bad'? If so, there are several forms of caster correction to look at. Cam Bolts, Control Arm Drop Brackets, Longer/Shorter Fixed Control Arms, Adjustable Control Arms. They each have pro's and con's, so do a little reading if you decide to raise the caster back into the 4+ degree range.

 

If it feels like a bobble-head, would check hub and bearings.Took me too long to figure out this problem with my Wrangler! And besides the obvious things, may check for steering slop. I upgraded to Big Bore and it helped a ton.
