Noise after Cavfab install

I've got everything installed and aligned. Wanted to see if this steering has caused any new "clunking" noises for anyone else post install? I know the drag arm rotates up and down a bit- could that "flopping" motion be creating a new -and normal- noise that I'm hearing from inside when hitting small bumps, manhole covers, pot holes, washboard roads, etc?

Re: Noise after Cavfab install

Is the drag link hitting the tie rod? If so loosen the jam nuts on the drag link and twist the heims a bit to restrict their movement, then tighten back down.

I would probably guess this as the drag link does have a lot of play. I didn't notice any new noises after I put mine on.

Re: Noise after Cavfab install

can you post pics? heims can clunk over TREs and bushings. you can try clocking your heims on both ends in opposite directions.

Hmm, I wonder! Will check it out in a bit. When you say twist the heims, you mean tighten? Otherwise, the heim on my pitman arm is already about 45deg.

Will do shortly. What do you mean by clocking my heims on both ends?

I think we're both talking about the same thing. Break the jam nuts loose, and screw the heim in or out of the drag link. If the heims are clocked in opposite directions, they won't be able to move around as much on the misalignment spacers.

yep clock one heim up and the other down. it'll help, and it can take out tie rod roll if you have it. I have had to pull over on the road before coming out of a trail to clock the heims on my D60 front before, sometimes they would rotate just enough in the right way to cause a dead spot if all my tie rod and drag link heims and hydro assist heims were all off just in the right amount. it was amazing how clocking them took out slop and noise.

Re: Noise after Cavfab install

Ok, so the heims, if you're looking at them from the side should (simply) look like an X instead of // ? I think that's the case.


I think both are //


Also, now looking at those photos, I'm wondering if the drag link is bumping my sway bar. And now I'm wondering why my sway bar is sitting so low. I've got the JKS adjustable quick discos, that I thought were properly adjusted..

Haven't gotten any bumpsteer- that I notice at least? Not sure if these are cheap or not. I get the impression that the CavFab guy doesn't think his stuff is cheap, and he calls the heims on his site: "Quality Heat Treated Chromoly Heim Joints"

They all call them that, but they use the same cheap midwest control chinesium that ruffstuff uses.

In that picture, the draglink should be on top of the pitman arm, not below it. Its kind of a shitty design, but right now its installed wrong.

I'm not saying they use bad joints or anything but its marketing 101.

Interesting. On their product page, the install video shows it going on below it: http://cavfab.com/CavFab-Jeep-CrossO...JMJ_p_105.html

I'm open to information. Why do you think it should be above?

Re: Noise after Cavfab install

Look again. Look at the relationship between your RE trackbar mount and draglink, and then look at theirs. Their draglink sits a lot higher than yours.




You want your trackbar and draglink to be parallel (pivot to pivot, so you need to draw a line on the picture between pivot points to really see it).

Your geometry is way off.

This video covers it pretty well.
