Re: Installing IRO's rear a arm..
Yes I did. I was installing it upside down. I figured the "Iron Rock" that was laser cut out in the webbing of the arm would be readable from below. But for whatever reason they made it so it would be backwards from underneath, whatever. Not to mention I received no instructions with my $300 arm. Not even a piece of paper. I don't need step by step instructions to install an a-arm but some blow up of the assembly would be nice, plus some instruction, torque settings for the ball joint. Anyways, this was last summer so.
After installation, all frustration was alleviated, the arm quieted my clunks and tightened up the rear. I took the Jeep to Colorado shortly after and it performed well on and off the road.
