Putting in new control arms

[Jackrabbit41]

Can I put in my new control arms without jacking the truck up? Like do one at a time? Also, for my upper adjustables, should I just set the length to the stock upper lengths? Thanks

That's how I did mine - on the ground. L-LCA, then R-LCA; L-UCA then R-UCA. Don't know about the adjustables as mine were fixed. I used shims on the WJ LCAs to dial in caster.

I did mine last month. I jacked up the front of the truck and let the axle hang. Easy-peasy. I used stock uppers and fixed Rancho lowers.
