2004 chevy silverado z71 torsion bar issues

[redvett]

Did you measure the angle of the hexagon on the old v/s the new arm? I am betting the arm is bad or wrong application, the P/N is not a guarantee that its correct. What was wrong with the old arm?

Did you use a torsion bar loading/unloading tool to remove/install the torsion bar key and bolt?  

[Harold Beaty]

The ball joint was out and the control arm bushings was rotted. No i didn't measure got two different ones and same problem on both. Yes I used the torsion bar tool 

[Harold Beaty]

going to order both oem control arms and hopefully it will fix the problem

LH 19186776    RH 19186777   these are AC Delco.   

Just make sure you put the torsion bars in with the label/tag to the control arm.

I don't pull the torsion bar all the way out I just loosin it up and let it hang there
