How To Hang a Sway Bar Properly

I just got under my car to unhook and install my torque arm. What I found was my sway bar is hitting my shocks. I have a moser 9 inch posi. The manufacturer of the sway bar says that moser will move their shock in up to an 1" and causes interfearance. The question I have is how to hang the sway bar .
Should the ends of the sway bar be parallel to the floor when tightened up?, in reference to load .
Should I tighten up the endlinks first , then tighten the sway bar bushings to the axle. This way I can see there would be no load on the endlinks.
Should there be any load on the end links ?
Do they not recommend a neutral load set up?

I guess what I am gettign at is if I attach my sway bar bushing parrallel to the floor. I get alot ot pull at the end links when I tighten it up. Is this the proper way or should it have no pull on sway bar from the start?

I hope you can understand what I am trying to say and

Thanks for any info folks.

Re: How To Hang a Sway Bar Properly

So did I basically answer my own question with the process I am doing. Any input from the masters of suspension tuning

Re: How To Hang a Sway Bar Properly

Well does it really matter where the bar hangs on the rear end? Can it be hung befoe center or after center ,looking at the axle tube from the end. I guess that is what I realy want to know. for any input

Re: How To Hang a Sway Bar Properly

Although I cant really offer anything spectacular, I can tell you what I know. It may or may not help you with your specific situation. As far as I know you are supposed to make all sway bar adjustments with the car at ride height, supporting the cars weight. Be that sitting on the ground, or the suspension supported by jack stands. Hand tighten the bar bushings then install the end links. Then tighten the bar bushing to the specified torque, followed by the end links. You can also experiment with diff. end link tension settings to minutely adjust side to side weight distribution. Be it for circle track, or for the perfect launch. Though most drag only cars dont run a front sway bar.


Max,

Re: How To Hang a Sway Bar Properly

Thanks for the reply myvmax1, I am setting mine up for more drag style running, my main concern was where the swaybar sits on the rear.
3rdgenmar, the torque specs for endlinks is 16ft/lbs and swaybar bushings is 18ft/lbs. I would watch the bushings though as they can split before you get to them specs sometime.

Re: How To Hang a Sway Bar Properly

Where did you get your torque specs 84TranzAm?

According to my Haynes manual, the front sway bar endlinks should be at 14ft/lbs and the front bushings were 25ftlbs. It says the rear endlinks should be torqued at 12ft/lbs and the bushings should be torqued to 20ft/lbs.

Re: How To Hang a Sway Bar Properly

I am just going by what I was told in an email when I requested tourque specs for my aftermarket parts.....I guess I should have staited that.... .....but I am finding different specs everywhere but mostly 16-18 lbs.....but I was told to tighten it up as much as possible on the swaybar if I am having movement issues......

Re: How To Hang a Sway Bar Properly

It does not matter where the bar sits location wise to the center line of the axle. Just as long as it is mounted equally on each side as not to put any unwanted preload onto the forward links unevenly.

I actually had my bar mounted about 30* backwards of the centerline axle (underneath and back if down is 0*) so that my forward links operated 90* of the bar without bind through articulation.

Circle track racing I actually put as many as 12 turns into spreading the LF swaybar heimjoint to preload the bar in certain conditions. Mostly I am about 4ts spread though. (Not a thrid gen, but preload related to circle track)
