my jeep seems to do its own thing when traveling at highway speeds and it gets kinda scary some times when im going 60 and the jeep wants to change lanes and i dont want to would my front axle not being centered cause this because i don't have a new front track bar and it sticks out about an inch more on one side or is it my castor?? i only have a 3.5 in lift with 3/4 in spacers with 33"s...i want to fix this problem before its causes a wreck.

 

its both, you need a adjustable trackbar and a set of upper adjustable control arms

btw if you have a 2 door like the pic shows, you should probley get a set of rear adjustables as well. You need to get the rear pinion straight. If you dont, you're going to wair out the rear driveshaft.

eventually it'll break

 

rear uppers or lowers? and thanks for the quick response

 

uppers should work fine, both if you can afford it.

 

X2. A full set of adjustable control arms should solve your problems.

I would stay away from the budget CAs. The bushings and joints tend to be poor quality and wear faster and/or provide a rough ride. Also make sure the arms have sufficient adjustment range, preferable in both directions (longer and shorter).

 

With my OME HD spring lift (3.25" of lift) and 33's on a JKU. I just added adj front and rear trac bars and added the Front adj lower control arms and got my caster set-up near stock and the floaty feeling went away and the ride is better than stock.

 

while getting your axle re-centered is nice, your main problem is coming from a lack of positive caster. at bare minimum, installing a set of adjustable front lower control arms and setting them a bit longer (about 23" eye to eye) will help out a lot.

 

Same problem here and I will eventually get the adjustable control arms and the adjustable track bars as they definitely are a big part of the problem although I think the wind on the freeways dosn't help either.. Does anyone agree

 

the jeep is a brick and no, wind doesn't help a thing

 

If you think your JK is bad try a CJ
