unstable driving... all over the place! scarry

Stock caster is around 3*, toe in around 3/64 to 3/32.
I never had to change anything on the 3b with a 2" lift.

 

3b? sorry, is that a model of Cj? if so mine is a 72 CJ5.

now we have a discrepancy here... lost again

 

The info came out of the FSM for my 1969 Commando.
The 3b is a 1961 Cj3b. just like it says in my signature.

 

got it, thanks, sorry.. p

 

Story: Firestone did the alignment the first time, not the usual place I go but the guys at the sports truck shop sent it there after they did a few tack welds for me,,,,, needless to say it was totally F'd up...It is now over at the "Tire Store" and with people I know and trust. They called me with how it was aligned and wheels were going in all different directions.... Caster was at 0, Toe was at~3/4, and Camber was way off......
Moral of the story: stick to those you trust.

I will report on the results tomorrow.... THANK YOU ALL!!!!!!

ps, for those that are having similar problems... get second opinions, even thirds.... good luck

 

Mcruff made me beautiful shims. In some locales they are not legal, meaning a shackle lift has to go, or axle work requiring welding, or angular cuts to the perches. Some will argue the last two methods are also safer(est) (rewelding axle)

I run 4.5deg and I can drive 70mph with one hand (as you should be able to).

my jeep was as basket case as well last year when I got it, with -1/-2 deg caster.

 

ok... went and got a real good alignment, and it is a gazillion times better..

This is what was given to do...
Toe:.........1/8"to 3/16"
Camber:......0 to 1/2* positive (shouldn't need adjustment)
Caster:........7-8* positive


But the Camber is still off... we had to order some special Shims... and we pulled the steering box out will replace it with a new one I got in yesterday. and there is a small crack in the mettle that goes from left to right frame above or around the box's in/out hoses. currently the camber in 0 for RW and 3/4 for LW.... The alignment shop feels that after camber is set to 0 it will be even better..... I will update in a week or so after the newest work is done.... but currently still a huge difference... thx, p

 

Is it getting loose when accelerating and decelerating or all the time?

 

I was having problems and found a rear u-bolt had come loose. Yousa!

 

Yes, it wants to pull left or right under accelerating and decelerating, but not near as bad as before,,,,

Mine seem tight..


UPDATE... changed the power steering box this weekend and also fixed a small crack in the frame above the box and under the radiator. I will have the final alignment done this week as the shims have come in for the Camber... will update with results soon.

 

You're not by any chance running a locker or spool with uneven tire pressures or diameters? That could make the Jeep pull to one side or another under acceleration or deceleration. Just a shot in the dark.

 

ok... this will most likely be my last post on this subject here...

All is fixed, ended up paying about 350$ in alignment fees... EVERYTHING was out.... got all new shims in and the jeep roles down the hwy at 70 with out a lick of problem.....


AAHH>>>> ok... maybe this is the last question.....Along the way to getting a proper handling Jeep I was having lots of things done to it in hopes to fix the problem....... One of the things that I had installed was a stabilizer of some sort..... This added stabilizer looks somewhat like a shock, but it is not. it U-Bolts up to the front axle and the other side to the frame. its purpose was stated to keep the jeep body and frame aligned during turning and the like... But I can't believe this doesn't wipes out the tire articulation off road... Is this needed?

 

It is a stabilizer in that it reduces the jerking feel of the steering when your tires are rolling down the road.

It works in a similar fashion to your storm door closer...the door gradually closes rather than slamming shut...the steering is the same principle, the steering won't jerk the wheel out of your hands, or allow for out of control wandering.

Some people say they aren't worth it and just mask problems.

 

first... cool avatar.... second, I ALSO have a steering stabilizer... I'm ok with that... what I am talking about is a rod/shaft/thingie... that mounts directly to the frame on one side and the axle on the other side... nothing to do with steering... p

 

Got a pic?

 

pauldana-What you're talking about is called a "tracbar" or a "panhard bar". They are generally used on vehicles with coil springs, to keep the axle under the truck. Ford did use it for a while along with leaf springs, but it wasnt the best thing they did.
