I just bought the jeep last week
so far I have replaced both sides wheel hubs
inner and outer tie rod both sides new steering stabilizer and alignment just the other day
driving down the hwy at 65mph and hit a bump and got DW
at 55mph I have a good shimmy when hitting a bump bt I can power though it until 65mph
I was told track bar
then I was told control arm bushings
what should I do?

 

Did you physically check the trac bar and control arm bushings yet. Is it a stock track bar. Is it lifted properly.

 

I checked track bar it is a little wabble bt not as bad as ones I have had b4
the track bar is an adjustable RE I think but the guy b4 me welded the jam nut to the tie rod end and to the bar it self so I'll have to buy new
I have adjustable upper control arms and fixed lowers
the pervious owner did the lift so idk of its done right bt it looks to be

 

bump

 

check trackbar bracket to the frame for cracks or any movement. you should have no play in the track bar anywhere except maybe a touch at axle side if you there is a clevite style bushing in it.

 

I would say I have about 1/8 inch movement at the tie rod ends (frame side)

 

just checked the brackets and there is no cracks

 

its toast. that will do it, but there are probably a handful of other issues going on as well. my $.02 is to start there.

 

Start with your track bar- that is usually the culprit. IRO makes a great one for not all that much.

Your control arm bushings could also be the culprit- they were on mine awhile back. Also ball joints. More than likely though, it is your track-bar.
