DrHolliday Curious as to why they didn't give you a caster reading...

Nothing looks too out of whack though. I've had my ESP turned off ever since I lifted it... ESP went off a lot before the alignment, was better after the alignment, but still went off. I just shut it off with the steering wheel dance. Every time it goes off it is applying your rear brakes and can wear out your rear pads really fast.

With it off you still have ABS, but no traction control (not like the jeep needs it) and no electronic stability control. Then at every stop it beeps twice.

scottmphoto Here is today's report.
05-21-2012 09:50 PM
scottmphoto Thanks STLRubi for your feedback. After more research, I removed the bracket. Steering is MUCH better and the Jeep feels more in control. Had it aligned today (second time in 2 mos) and the TC came on again on the freeway.

The only thing out of spec is thrust angle.

My question to you....should that bracket have gone on the rear to keep the axles parallel? I no longer have the install docs for the TF lift.
05-02-2012 03:23 PM
STLRubi Not sure why you have a front drop bracket installed on a 2.5" BB. TF recommends this for a 4"+ lift in combination with forged drag link flip kit. TF 2.5 BB and spring lifts only include a rear drop bracket.

scottmphoto Newb question.....how do I adjust caster/pinion?
04-22-2012 12:38 AM
BobbyM with a JK you can achieve ALOT of caster and still keep decent pinion angle

their is a fine line between having good caster and getting your pinion angle, pinion angle is more important

those specs don't look to bad, doesn't look like you need adjustable control arms yet, i would look at your track bar/drag link angles. it almost looks like you could remove the track bar drop bracket

scottmphoto Verdict is in...courtesy of Les Schwab. The Track bar relocation bracket had 3 bolts. None of which were tight. He torqued them up. My alignment wasnt bad ( I did some of it at home last night).

She drives like a scolded cat again!!!!
04-16-2012 01:52 AM
darkproximity dang thats high pressure!

you can tell from the 2nd to last picture you posted that your trac bar and drag link are at very different angles, i guarantee you this is giving you the negative steering input. i've driven a tj that had bump steer and man i agree it makes you nervous. i'm not saying that you DONT need to adjust caster and toe in, but the majority of the holy crap factor is coming from your misaligned angles.. if you take a pic just like that 2nd to last one, but just a tad further back i'll photochop some lines over it and show you what im talking about.

Not yet.....Cold talked me through a self-alignment tonight. Tomorrow I'll air down a bit...I am running 65psi right now.

scottmphoto Here are some shots I tool quickly in the dark. Not sure if they help or not.

scottmphoto @ Dark, I got home late tonight and will post a pic in the daytime.

I did some DIY alignment tonight (many thanks to Cold) and it helped a bit on the surface streets but TC (traction control) still engaged on an I5 onramp and had to be switched off. When ever I let off the accelerator, its a hard pull to the Right. On the gas, it seems relatively OK. Then we just have these totally random TC engagements....

Will take it for an alignment tomorrow by a pro shop.
04-16-2012 12:33 AM
darkproximity Also, did you install a drop pitman arm?
04-16-2012 12:21 AM
darkproximity I'd still be interested in seeing a picture, just because teraflex sent you a bracket doesn't mean much to me, ive seen the wrong parts be sent before. something as bad as he described where he feels its unsafe to drive.. then there is something wrong there. even slightly different angles will give you negative steering inputs. one of the reason i advocate yj owners to ditch their track bar all together. obviously not an option for coil springs so you'll have to really get a good look at it.

this becomes a problem on any vehicle with trac bars when you lift them and don't address the steering.
We installed a trackbar drop bracket that came with the Teraflex kit.
04-16-2012 12:17 AM
07UnlimitedX These angles were not changed for the installation of the lift. The lowering bracket was installed, thus keeping all angles within close proximity of the stock angles.

darkproximity pardon me butting into your local thread, but your steering issue is no doubt coming from true bump steer, if your trac bar and drag link dont travel in the same arc then you will definitely get bump steer..

take a picture of your axle from the front so you can see the steering linkage and the trac bar.

07UnlimitedX Adjustable control arms are a worst case scenario. I'm up 4"+ on stock control arms. Did you try lowering tire pressures a little bit?
04-15-2012 11:56 PM
scottmphoto Thanks Robert....

I guess I'd like someone with experience to just take it for a spin...and let me know what they think. Can we pick a time where we could meet up?

On the adjustable CAs, is that something I will absolutely need or just a worst case scenario?

She's a daily driver for me, so I need to order anything possible soon..

I do feel some bump steer issues, but I also feel like I am constantly having to steer, even on straight stretches of road. Almost like a boat at low speed....just feels odd.

Any feedback greatly appreciated.

Cold Scott,
Sorry to heat about your issues

Bump steer is when you hit a bump and you feel it in the steering wheel or the Jeep bounces around. You have a bracket installed to correct this behavior so I would try a quick and easy fix like letting some of the air out of your tires. That can help a lot. If you are running higher pressure with E rated tires and stiffer springs it can bounce all over the place and feel highly unstable. Drop it down to 30psi and see if that makes a difference.

As for the amount of lift, technically you only have 2.5" of lift. The higher spring rates of the Rubi coils just hold the weight better so its closer to where the factory intended it to ride. They arent actually taller, just stronger so they sag less. The Teraflex track bar bracket should account for this.

With lifting the Jeep you lose caster and the only way to fix that is with adjustable front lower control arms. They aren't to difficult to install. Just a few tools. If you need a hand there are a few of us that can help you out.

TheRock Boo! Looks like we have another work day in our future, eh? It felt ok in second gear.

Yup, easy to install, do a little bit of reading, I'm thinking I recal if you set the length to 23" center to center on them then your caster should be close to stock specs.
