I just ordered front upper and lower Rock Krawler control arms. I was planning on installing them myself. Does anybody have any advice on getting everything square and even. I figure I will have to get it aligned but I want to get it close. Thanks for any help.

 

Measuring tape, or a long Vernier caliper.

 

Angle finder and measuring tape.

 

What is the best pinion angle? Really don't want to take the uppers loose to change castor after the alignment. I have a 3.5 inch lift. hoping I can find a shop that will help adjust arms to dial it in, but that might be to much to ask. I have read 6+ is best.

 

This is my wife helping me install the new control arms. I used the measurement's provided from Rock Krawler and got a 5 degree pinion angle. Have not got it aligned yet, but it drives alot better than it did with the Aev brackets. Look forward to getting the rear arms. The Aev control arm brackets are for sale if anybody is interested. $75 shipped in U.S.

 

You will probaly find their measurements to be pretty darn close and probaly won't have to go any further. I have a 4.5" kit and my castor is about 5.25 degrees and it drives great with no vibrations. Definately get it aligned as changing the castor angle may of thrown your toe off though it won't be much.
