will7798 Posted April 21, 2016 Share Posted April 21, 2016 So I got some bump steer the other day (hitting a bump and getting death wobble) and decided to look under there and see what was up. Everything was tight and the only bushing that was in question was my passenger side UCA but it still wasn't bad. Then I saw this...and wondered if it could be the culprit So what do I need? The PO lifted it 3.5 inches and said he did everything to get it back to stock geometry, did he forget the extended links? Or do you not need them for a comanche? Also is this even a stock sway bar? It didn't seem like it to me just because of how much of an awkward position it was in and the fact that the bolt in picture 3 wouldn't tighten any more and seemed forced.

87Chief Posted April 21, 2016 Share Posted April 21, 2016 I would search for sway bar extensions for a 3" lift Here's a link to some, they should fit the comanche http://www.4wheelparts.com/Suspension/Sway-Bar-Link-Kit.aspx?t_c=1&t_s=101&t_pt=4306&t_pn=EXP55597B Link to comment Share on other sites More sharing options...

HOrnbrod Posted April 21, 2016 Share Posted April 21, 2016 Your sway bar end links are too short plus the bushings are shot. http://comancheclub.com/topic/48447-sway-bar-end-links/?hl=synergy&do=findComment&comment=493423 Link to comment Share on other sites More sharing options...

will7798 Posted April 21, 2016 Author Share Posted April 21, 2016 Alright I'll order those up. Update though after driving around without the sway bar I'm still getting wobble so I'll have to do some more troubleshooting. Link to comment Share on other sites More sharing options...
Rockfrog Posted April 21, 2016 Share Posted April 21, 2016 Sway bar won't have any effect on death wobble. If you suspect the upper control arm bushings ... Replace them, they will have a large effect. As will Trac bar, lower control arms, drag link, tie rods, alignment (caster and especially toe in) and to a lesser effect wheel bearings, bad joints. It all adds up, and diagnosing is troublesome as by the time you ID one cause, more damage has been done to another.

Megadan Posted April 21, 2016 Share Posted April 21, 2016 Even with the moog links you will find the bar and link still touching the springs, or extremely close. I had to install a set of drop brackets for the bar to clear the springs. I went with a set from Rubicon Express, but I don't like how far down it drops the bar and I am looking to switch to the same type Hornbrod is using, which I believe are these. I am sure he can confirm that is the right part for us. http://www.synergymfg.com/Synergy-Jeep-JK-Rear-Long-Travel-Upper-Shock-Mount-Sway-Bar-Relocation-Bracket-p-29981.html Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 21, 2016 Share Posted April 21, 2016 That's them. I got them originally for my JK to provide a little more clearance for the fatter rear OME shocks I use, but they work even better on the MJ front sway bar. The brackets move the sway bar down and forward and provide a bit over an inch of clearance between the end links and coil springs. They also maintain the optimum bar end geometry, 10-20 degrees above horizontal. Link to comment Share on other sites More sharing options...
Megadan Posted April 21, 2016 Share Posted April 21, 2016 The part I am interested in is the more forward position. The RE Drop brackets I have move them more down by almost 2 inches, and only a little bit forward. These seem to go down a little but more forward, which I like better for clearance reasons.

Eagle Posted April 21, 2016 Share Posted April 21, 2016 Sway bar won't have any effect on death wobble. It also won't have any effect on bump steer. Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 21, 2016 Share Posted April 21, 2016 Sway bar won't have any effect on death wobble. It also won't have any effect on bump steer. No sheite. Great info and correct. OP, you should fix the sway bar anyhow. Link to comment Share on other sites More sharing options...
Eagle Posted April 22, 2016 Share Posted April 22, 2016 Great info! OP, you should fix it anyhow. I agree completely. Driving an XJ or MJ without the sway bar is dangerous even at stock height. With a lift it's considerably more dangerous. Link to comment Share on other sites More sharing options...
will7798 Posted April 22, 2016 Author Share Posted April 22, 2016 I plan on replacing it when I do my 4x4 conversion next weekend. I'll do fine without it til then and when doing the conversion I'm gonna have my buddy who's helping me (he has had more than his fair share of Jeeps in his 40 years of mechanic-ing) take a good look at everything and tell me what I might be glancing over and what needs replacement. Thanks for all the input! Link to comment Share on other sites More sharing options...
oldseddie Posted May 16, 2016 Share Posted May 16, 2016 Bump steer is usually from poor front track bar geometry on a Comanche. When I replaced my rustys adjustable double sheer bar with the appropriate jks bar it drove much better.

mikekaz1 Posted May 19, 2016 Share Posted May 19, 2016 ive driven my lifted TJ with no front sway bar for 5+ years, and I just put one on my MJ after 2 years without. yes theres more body roll, no its not uncontrollable. its really personal preference whether you like it, and can handle the vehicle still based on personal skill.

Megadan Posted May 19, 2016 Share Posted May 19, 2016 I drove my MJ for a week without the swaybar connected while I waited for my new links and bar drop brackets. The front bar on these vehicles isn't very big, so the difference, while there, is minimal, and without a rear bar, it already leaned over in corners enough to reel in my cornering speeds. I never felt unsafe without it, just had to be mindful of how I took corners and sweepers. Link to comment Share on other sites More sharing options...
AMCJeepMJ Posted May 20, 2016 Share Posted May 20, 2016 Get some nice poly bushings for your bar and it'll stay flatter on sweeping curves. Easy and effective upgrade. Link to comment Share on other sites More sharing options...
Rockfrog Posted May 23, 2016 Share Posted May 23, 2016 I have driven my 00 XJ without the front sway bar installed for about 2 years before adding the TJ bar. I did go with a much higher spring rate in the front though. Was fine around town and on the highway, as mentioned I just had to adjust my driving habits accordingly. Having the Dakota based bastard pack (with overloads still) and a higher rate in the front, makes it drive closer to a stock XJ really. Now with the TJ bar up front ... For a lifted XJ ... She handles tight. But, I also don't drive my XJ like a ricer, I have the MJ for that. Sent from my SGH-I337M using Tapatalk Link to comment Share on other sites More sharing options...
DirtyComanche Posted May 23, 2016 Share Posted May 23, 2016 Is the TJ bar significantly thicker than the XJ one? Link to comment Share on other sites More sharing options...
Rockfrog Posted May 23, 2016 Share Posted May 23, 2016 Considerably, 32mm and straight across the front. But my current bar position is a fair bit forward of the stock position which makes the TJ bar possible.
