Possible bent wishbone

[tidyclio]

Recently my cars steering has felt almost unconnected to the front right wheel and like both wheels are pointing in different directions. It was tracked quite recently so i decided to see what's what by putting my original shocks back on.
I noticed that my drivers side wishbones (4 months old) has a small groove just next to where the arb linkage is. You can definetly see a line that looks like a stress mark although comparing it too my old one's theirs isn't to much difference.
The steering wheel has to be help at the 2 o'clock position to keep the car in a straight line and when i'm hitting bumps and one wheel is loosing traction you can feel the car take a different line and almost skip across the road.
So would all this indicate that the wishbone is bent?I have and old one to put on but the bushes arn't in the best of condition and i have found that the arb links seem to fall to pieces when removing them so don't want to change it to find out it's normal.

i would say a bent wishbone are a knackered ball joint.

Balljoints are under 2 months old and they seem ok when i looked the other day.
Thing i don't really understand is the steering needing to be held to the right. /\ imagine thats the drivers side wishbone it's the half on the right hand side that has a small kink and i would understand this causing the wheels to point to the right but would have thought it would mean i would be holding the steering wheel to the left to correct it?
Going to swap it anyway, do these arb links always need replaced after been disconnected i.e my last set the bolt was worn away and the rubber broke up and i would need to go and buy some before i think about changing it?
