So i have a pieced together 4.5in lift kit do you need to replace the lower control arms when you lift a xj i got death wobble trying to chase it down. All i have with my pieced together lift btw is leafs coils shocks and relocated and new track bar.

 

Of course you do.
As the rig goes up the axle is pulled back and the caster changes.

 

You really should replace both upper and lower arms with adjustable ones.

With that being said, your source of death wobble could be completely unrelated to your stock CA's.

 

I had a death wobble before I lifted my Jeep. Lifting it fixed it.

Replacing all of the suspension components and some of the steering components obviously fixed whatever the problem was. Maybe you'll get lucky like me. Replace what has to be replaced first, and then keep going from there.

 

What do you mean relocated and new trac bar. Is it a trac bar made for a 4.5" lift like a DS one per say or is it stock and just relocated?????????????

 

Yeah it's a stock one but relocated I have figured out I think just need the parts to get here

 

Good, so those parts include a proper sized trac bar that goes into the stock position and not a quick fix bad idea relocated one, rigggghhhhhhttttt

 

Going to a 4 1/2" lift requires quite a bit more money than a 3" even a lot more. You need to start reading all the information on lifts or you would know this.


Things like better steering a new HD Adj. Track Bar, Adj. U/LCA's, new extended brake lines, SYE, Driveshaft and yes the list goes on. But it sounds like before you need to rebuild the frontend on your XJ before you do Anything! If you don't it will only get worse.

 

There you go
