After putting my car back together with new(used) parts, I put the car back on the alignment rack.

History:
The car had a collision on the front right passenger side causing the alignment to go out of whack so following suspension components were replaced:

Upper Control Arm (used)
Lower Control Arm (used)
Outer Tie Rod (new)
Strut (used)
Passenger Side Sway Bar End Link (new)

Picture of the carnage before any repairs were made can be found here: https://www.s2ki.com/forums/index.ph...pic=755681&hl=

After the alignment, the car is posting:

Front Left Caster: +5.5
Front Right Caster: -3.1

The only components left to replace are the knuckle and sway bar. My mechanic told me he fixed the control arm mounting points as they were slightly bent. The car drives "fine", minus pulling to the right side due to the caster. Also the passenger tire is noticeably "off centered" in the wheel well, there is a 4 finger gap between the tire and the fender on the driver's side, whereas there is a 3 finger gap on the passenger side.

Where should I go from here? Should I just go ahead and order a new knuckle and sway, then see what comes up on the alignment?

 

It may be your knuckle. My worry is that that front sub frame is damaged.
