rock krawler long arm question

I traded my 89 YJ for my 04 TJ it already had a lift on it which I was told is a rock krawler long arm lift, I was looking under the front of the jeep and saw some thing missing, it only has 3 long arms, 2 on one side and just one on the other, is this correct? or is a arm missing?

yep, looks like a rock krawler X factor long arm. Has a 3 link setup up front with two long lowers and one long upper on the driver's side along with a triangulated 4 link in the rear. It is a nice setup and is not supposed to have the arm on the pass. side.

Does it look like something is wrong with the lower arm mount.

thanks for the info, I had a problem with the pan hard bar bushing, it came loose and gave some DW like I only saw once in a car i thought was gonna turn over but got that fixed and it seemed to have some vibration in it it did not have when I bought it, I think from what I have read I think its in the tire balance but now I know what a "three link" setup is.

Might be from the arm flexing hard. He could loosen the jam nut and twist the link end to get it centered again.

It is normal and not an issue for the flex joint to be turned like that. The rock krawler joints have a higher degree of misalignment than most so the joint has a different "look" to it and the doesn't have as large of a housing as others (such as currie johnny joints or RE superflex), and thus, is more obvious to see when it is flexed. The joints are designed to move and flex but the axle position does not change because the thru-bolt center of the joint is what controls this, and it stays constant. If it drives you crazy, you should be able to just loosen the jam nut and use a pipe wrench or channel locks on the arm to square the joint back up in the mount and then re-torque the jam nut.

That is not normal.
"The krawler links have the krawler joints at one end and urethane bushings at the other end to dampen vibration."
The one in the picture is the urethane bushing end...

If we are talking about the axle end, that is the RK krawler joint (http://motionoffroad.com/catalog/ind...image&pID=1129). Every RK long arm I have ever seen in person runs the flex joint at the axle end and the bushing on the frame end. However, the pic in this link shows flex joints at both ends so mabye it was different depending on what generation kit you have.

If you are referring to the frame end, then you very well may have a point if it has a deformed urethane bushing. I am having a hard time making out that end in the pic. I am simply making the point that it is not unusual for a flex joint to be turned to one side or the other inside the CA mount.

Wrong.

The Krawler joint is on the axle end. You can even see the retaining plate on the joint.

This happens to my short arms once in awhile. All you have to do is loosen the jam nut and twist the arm/joint back to center and tighten it up.

From what I can see from the picture it looks like he has a first gen three link kit. It also looks like he has a Krawler joint at the frame end too.
