Just bought a jeep and it has a 4 inch pro comp lift. The passenger side tie Rod end is damaged. My question is, would this cause wobble? It feels like death wobble to me, but I'm not an expert and this is my first jeep. It really only happens when I hit bumps at slow speeds (15-30mph). It feels fine and has never happened at higher speeds171220

DW is almost uncontrollable and will make you scared to death to hit any bump. If you don't have this, then it's just bump steer or a shimmy. Either way, a loose tie rod could cause both. Is the joint loose or just a torn boot? Either way it should be replaced, but if it doesn't have play, you probably have something else going on.

That would be bump steer. Could be tie rod. Could be you have something loose and need to check torque. Might not hurt to also do a drag link flip since you are running 4"+ lift.


I'm sure others can share more specifics on how to fix, things to check. [emoji106][emoji106]

Can you post a picture of your ball joints on each side?

I need to get channel locks and check. I have checked the torque on the track bar and almost everything else. I have the check lest to run but can't do it until Thursday or this weekend. I'm just trying to get an idea. The track bar has some movement at the adjustment nut can't think of the name right now", but it is torqued and doesn't move anywhere else. I am the 4th owner and it is a. 13 and has 9K miles. This is my first jeep so it's all new to me.

That's very possibly the source of your shimmy. Track bars take very little movement to allow DW or shimmy to occur. Also, as far as checking your tie rods, don't use channel locks as the ball and socket joints sometimes will have slight up and down play, Instead have a friend turn the wheel back and forth while you visually watch the tie rod and see if it has any horizontal play in the socket. You could do this yourself with a video camera as well.

Ball joints look fine.

You need to tighten up that trackbar jam nut, and cycle the steering to check your tre like ^^ said. Check your ball joints using a floor jack under the axle, and a pry bar under the tire at 6, prying up towards the fender and check for looseness.

I knew I had to tighten the jam nut, I'm going to do that Thursday. I will see if the shop I am using will let me use a Jack well. I found another post that mentioned got having the gap in the clamps lined up with the gap on the adjustment sleeves on the drag link. Fixed that, it was no help. Hopefully tightening the jam nut works. I already plan on ordering a synergy tie rod and teraflex track bar, but it would be easier on the bank account if I could spread them out.

May I suggest u look at other track bar options. The tf track bar has been known to snap at the top end of the threaded area. I have seen this personally, and a few people on here have posted pics. I have jks ones, and have run them since 09.

Thanks that's good info to have. I was looking at that one first, I'll prolly stick with that. But now I have a whole new problem with a leaking fluid. FML!!!

What color is it, and where?

Edit... Nm I answered your other post. It's the ac/heater box drain.

So I tightened the track bar and I'm still getting crazy shakes when I hit bumps at low speeds. My drag link and track bar are not in the same plane, is that a possible cause? I'm gonna check my ball joints tonight

How did you straighten the track bar?

I mean one is at a more steep angle than the other. I though I read somewhere that they should be at the same angle.

It is the angles created by the mounting points that u want level.

Ok, I'll check it out tomorrow. I took the track bar completely off today noticed the ones on the passenger side are way bigger than the bolt. They are not ovaled but it fits in the track bar perfectly. Also, the track bar was pulled so far to one side that I had to screw the bolt all the way out, it didn't just pull out. So I adjusted that. I didn't get any crazy shakes on the way home so we will see in the morning. BUT, my traction light came on. This is never ending already

After watching those videos, I think you're ok there personally. You're track bar will move when you loosen that bolt, fyi, You may have to adjust that back the way it is. The trackbar keeps your axle centered under the Jeep, and with the coil springs, your axle will want to naturally favor one side, so.... to get it centered, that bar will be under 'tension' in its correct position which is why it was hard for you to get the bolt out.

Did that lower bushing have any movement when the vehicle was still assembled while someone turned it. If not, there's nothing wrong with that end of the track bar.

Also when you put that bolt back in, be very careful not to damage the threads on the end when you put it back in.

No it did not. I also checked the ball joints and there was no problem there. So right now the only thing that I have found that's messed up is the passenger tie rod boot. I still need to find a angle finder and et the caster and I'll check the toe soon too. To me it feels like all the wobble starts from the passenger side.

Check wheel bearings too. Make sure your axle is centered correctly after track bar is re-installed (you may have to re-adjust it to where it was before). You could have a tire issue too. You could always rotate tires front to rear and see if the issue goes away or gets better.

What are yalls thoughts on the synergy tie rod? Is there a cheaper, better alternative?
