Caster adjustment with uca's

Can caster be adjusted just from the uca's without screwing up the rest of it?

Using LT Racing uca's and have frozen cams in the lca's, caster is at about +1.7, really could use some more, at highway speeds the tracking sucks pretty bad.

Is all this dependent on the current position of the frozen cams?
I know I'm beating a dead horse, I can see the lca's being cut off in the very near future and replacing the bushings and cams, but I have to ask...

 

Check your air pressure in the tires first to make sure your pull isnt from that. Im not familiar with LT racing but I would check with them to see if they incorporated adjustment into the arms for caster. Usually caster is adjusted in a lca because adjusting caster in an upper will also effect the camber

 

Yes you can clock the LR UCA ball joint to increase / decrease caster but it is in set degree increments

 

I gave the wrong numbers, sorry for that. I just returned from the shop and had them print it out for me.

Looks to be close, I'm thinking I may need a bit of negative toe, or toe in. The shop suggested to try that first as it can be done in the driveway

Caster 2.52 Left
2.46 Right

Camber 0.48 Left
0.29 right
Toe-- 0.07 both sides, total of 0.14



Off to change toe in, I'll report back later...

 

Good call, I did check, they are at 34 psi, new tires, not worn funny at all.

 

Update, Success!
turned tie rod ends 1 turn out both sides.
75 mph, tracks straight, one finger steering, doesn't pull. Hits bumps, irregularities in the road and returns to center easily.
Steering wheel sits just slightly to the left, that may be the crown of the road, it's not enough to kick in the OCD so I'm gonna leave it for now.

Thanks for the input guys
