So I took the freshly lifted jeep on the expressway today. Got up to speed no issues expect at 55mph exactly the front end shimmy's a little bit. Doesn't matter on how flat the road is. Stops as you get closer to 50 and up to 60 and doesn't happen anywhere else.

I've heard this is tires?

 

did you have it aligned after the lift and sounds like u have a minor case of the death wobbles

 

My stock xj does this. LCA bushings?

 

It's not really Death wobble. I've had death wobble and this isn't it. I've checked all the steering components and everything is tight. As for the lca bushings not sure. Sounds like a pain to replace tho

 

bad hubs, worn out tires, unbalanced tires, out of balance driveline, bad ujoint, toe out of spec, i would check those out first. Most other things will be prominent throughout the acceleration and or deceleration to a certain speed.

 

My tires are DEFINITELY on the way out. The two in the front have bubbles? So that's a possibility.

And I'm pretty sure my alignment is still off. (toe)

As for everything else, last time i did a run-thru it all checked out.

 

your tires are most likely the cause. To check your toe measure the distance between the front of the tires and then the back of the tires, i usually toe mine in 1/8"-meaning the front is 1/8" closer then the back
EX. Front-66.5"
Rear-66 5/8"

 

How did you get the bar to move easily? It was so hard to get it to rotate enough to get any change?

 

What do you mean? the sleve on the TRE's? loosen the two bolts and pb blast it, then do it. or unbolt the TRE and twist it

 

The sleeve. It did not wanna rotate even with a pipe wrench.

 

i had a bad shimmy on mine rotated the tires ahd replaced the steering stabilizer that i replaced a week before got the shimmy

 

did u put new tires on when u did the lift cuz u prbly just need to replace tires, but an alignment wouldnt be a bad idea either

 

I know I need new tires. And the alignment is still off a little. I think it's a combo of both.

 

You're tires aren't balanced. Get them weighted and it'll go away.

 

You should set your toe first. It isn't a good idea to drive the Jeep if your toe is off it will wear your tires and put stress on your suspension components.
