Just note that when setting your caster, your also changing your pinion angle.
Unlike the rear, a properly aligned front end will always been a compromise between good positive caster and pinion angle. The more caster you have, the better your steering will feel at highway speeds but the more chance you will get drive line vibrations. A pinion angle that is in line with the front drive shaft will leave you with negative caster and that will give you terrible handling. About +4° or stock caster is the best you can really hope for.
Also, I noticed the write up goes from UCA's and skips to LCA's.
Adjustable LCA's are technically used to position your axle and the UCA's are used to set caster. If you can only afford to get one set, LCA's are much easier to install and make adjustments to. The write-up would still be the same only on the lower arms.
Overall great write up, I wish all the forums write ups were converted over here. Much easier to read and see pictures when printed off!
Glad to hear you like it better here. I intend to move them all over as time permits.
