3 inch lift issues

I have owned a few Jeeps over the years but this is the first TJ. I have a 2002 wrangler that I bought with a 3in. lift. This thing is all over the road. The faster you go the worse it gets. I took down to a place and had the ball joints and a front end alignment done to it and its no better. A friend of mine said its got the death wooble going on and said to put adjustable controll arms in and that should fix it for a couple hundred bucks. There is new rancho shocks in to. Another guy said put new tires on it. What do you think?

Re: 3 inch lift issues

If you have "death wobble" you'd know it! The steering wheel will start to shake violently, usually after hitting a bump and the only way to recover is to slow down... WAY down! Another issue is bump steer which can be caused loose or broken parts, or an angle difference between the drag link and track bar... they should be at about the same angle. Parts that are usually identified as causing these issues are loose or worn out track bar, tie rod ends, ball joints, and even hub unit bearings can be involved.

If you've had the alignment performed, the castor should have flagged if it was out of specification. This is a common problem for lifted TJs, and you may need adjustable lower control arms to bring the castor into spec to resolve your problem. A GOOD 4x4 shop should be able to help you get it straightened out. I ran 35s on a 4" lift in my old TJ for years with no problems once I got the castor dialed in. YMMV!

Have you checked that everything is tightened to spec? Many shops show a shocking disregard for torque specs on bolts, but the SFA design only works right if everything is completely locked down. Slop in your bolt tightness will filter through the entire suspension.

Re: 3 inch lift issues

First off do you have the dropped pitman arm installed that came with the RC lift? If so remove it and put the stock arm back on. Second what was your caster reading from when you had it aligned? Start with the pitman arm first. Then get a buddy and do the dry steer test. Have someone turn the wheel while you are under the jeep looking for any parts that have excessive movement. Make sure the front end parts are good and tight without play.

Everything is good on the front I'm going with adjustable control arms. It's not the death wooble it just floats all over the road.
