After lower control arm and ball joint replacement - what is THIS symptom?

[cfauvel]

So just finished replacing the lower control arms , outer tie rods and lower ball joints on a 2005 G35 sedan

The symptom is when I turn the wheel left or right near the full rotation, the wheels wanto grab and immediately finish the turn quickly lock in that direction. I have to hold the steering wheel from shooting left or right after a certain angle of the steering wheel.

I haven't taken the car to the alignment shop, yet...but not sure there is anything OTHER than toe-in that is adjustable.

Would too much toe-in create this symptom?

I suspect it is the other control arm (rearward facing - from knuckle to body to set the caster) But they look fine.

Spoke to a buddy of mine...he believes the symptom is caster related and that me tightening everything with the car up in the air/unloaded has things out of spec.

was going to take it in for alignment anyway.

I wasn't having the symptom with the bad bushings in the control arm, so it has to be something peculiar with my installation of the new parts.

UPDATE: all is good after the alignment. The caster number DIDN'T change at all from Before/After...but they said there were some loose bolts...hmm I remember torquing them down to specs.

What I THINK happened is that I tightened everything with the car jacked up, so there is was no load on the suspension....thus got things out of wack.

Now to do the same thing on the 350z.
