ok tonight i was running down the road and my jeep started to shimmy really bad..then it stopped..couple minutes later is started back and wouldnt stop until i stopped...its been fine since i bought it a few days back..do i need a new beefy steering stabilizer?or even dual kit?what brand?(stock still on there but not leaking..not sure why original owner left it with 6"lift on 35s) or do the tires need to be balanced? i need this fixed asap..with driving this as a daily driver..cant go down the road feeling like im going to lose control...thanks very much..!!
