Control arms - Ball joints

[jmudler]

I have a question about upper control arms (UCA). I noticed two different models from Moog.

CK620054
Front Upper; Incl. powdered-metal gusher bearing to allow grease to penetrate bearing surfaces; Standard bushing

CK620053
Front Upper; Incl. powdered-metal gusher bearing to allow grease to penetrate bearing surfaces; Incl. offset bushings offering an additional 2 degrees of camber change

1) Would CK620053 be a better option if I do leveling keys to aid in camber/alignment?

2) I plan on using my 20 ton shop press for the ball joints, and when I remove the lower control arms to replace the joints and bushings do I need to worry about the torsion bars? In other words do I need to decompress the torsion bars via the torsion keys?

Thanks

I can't say for sure adding 2 degree's is necessary just for cranking your Torsion bars, but thoughts are they are not needed.
I can say for sure, you don't need to remove the upper and lower control arms to replace the ball joints. A lot of work involved in doing that. I replaced my ball joints (upper and lower) with the control arms in place. I used a Ball Joint removal/insertion tool kit, like this http://www.harborfreight.com/ball-joint-service-kit-for-2wd-and-4wd-vehicles-60827.html#.UyDx1NfD9Bk The lower ball joint needed a bit more persuasion so some PB Blaster and a hammer finished up the removal. The kit made it easy to put the new Ball Joints in.
