New lift and a new Wobble

I just finished installing a RC 3.25" lift on my TJ. It drive great until I hit a bump at the right angle. Then the front end right side (passenger) starts to wobble like the tire was out of balance. I had to move the track bar over like the direction said but now it has a little bit of travel in it could that be the problem? or would something else be the problem?

The track bar having ANY play whatsoever is a huge problem. We call it Death Wobble. Luckily your getting small doses and not overdoses like ive experienced. Buy an adjustable front track bar and put it back in the stock hole and torque down to spec. I dont recommens driving until you do so as you will likely ruin other components if it continues to happen.

Did you install a drop pitman arm with the kit?

Wait, no play in the track bar is good, none. Did they have you drill a hole in the track bar bracket on the axle side?

There should be ZERO play or movement in the track bar at all. Its what centers your axle.

I would address returning the strength to the bracket by welding a plate with the hole (aligned with the original hole) over the bracket.

Maybe you drilled the hole a tad too big?

So I'm afraid to ask but I am compelled. Which track bar did you order?

Good deal, drilling a new hole like all these kits tell you to is actually not very smart at all unless you actually take the time to weld on reinforcement plates.

Hope you bought a good one. Before Installing your new track bar, it would be a good idea to weld a piece of 1/8" plate over the existing bracket to strengthen the now weaker bracket and re-drill the original hole. Then after you get it all bolted in place and before you drive it, adjust the toe-in.

I don't think you'll get good clearance with that brand. In fact you'll possibly have to add bump stops that take away all or most of the "lift" you just added. Research is key if you want to build your rig without throwing your money away or buying the same component multiple times and being dissatisfied each time. I hope you get it sorted out and enjoy your rig.

You should cancel it and get one of these. TJ/LJ Jeep Wrangler Solid Chromoly Front Track Bar or these Currie Johnny Joints Suspension TJ LJ or these JKS OGS125 Front Adjustable Track Bar for Jeep TJ/XJ/MJ/ZJ : Amazon.com : Automotive

The ProComp offers no clearance at the differential when flexing. I believe it was Iped that posted a picture up just the other day of a broken one after it hit the dif.

Also factor in bushing strength. Over time bushings fail. The three WaterDog listed are well known to last much much longer than ones like Procomp, Rough Country, Skyjacker, etc.

good choice, the JKS #126 (hopefully what you got) is one of the better clearance bars out there, but don't forget you'll still need about 2" front bumpstop extensions to keep that track bar from hitting the tie-rod. (drill and tap the spring pad for 1/2-13 UNC then bolt down some 3" OD Body lift pucks)

while you're at it, you might as well setup the bumpstops in the rear to, so you can prevent other damage too.

So i basically have the same kit minus shocks an BL... I'm getting a pull to the right and not so much as a wobble, more of shimmy. I have checked all my front end component and everything seems tight. So a longer/adjustable trackbar will solve this problem?

You might get more input if you start your own thread.

maybe, maybe not. too many factors to guess. get an alignment & get your tires road force balanced, and post the specs in your own tread.

I already got the alignment done when I had my tires mounted and balanced. I don't know what I did with the sheet they gave me but I remember before it was way out of alignment up front. Now it's more of a floating feeling than a pull, it's like driving a boat.

Also, I have 2.5" of spring lift with the factory track bar. All the tie rods seem like they're ok

without the specs from that sheet it's going to be really hard to help you.
