Losi Mini T Steering slop - Help Please

[JezT]

For the few that run Losi Mini Ts (and in particular Scotty). I am have problems centering my steering after left and right turns; Its not the servo (savox 257mg with "tightened" XTM rage servo saver) as, at the end of the servo saver arm (ballstud), it always returns to the same point; I put it down to slop in the front end components - It's mounted on my Exotec buggy - Heres what I've got:

Standard Losi 3.85mm Ballstuds (Brass colour)
3Racing Ball cups
Losi TI Turnbuckles
K-Factory Hubs,Hub Carriers,Arms and Centre Arm mount
GPM Steering arms

I notice movement of the Ball Cups on the Ballstuds - What Ball / Ballcup do you use? Could this be the main problem?

The joints between Arm&Centre bracket, Arm & Hubcarrier and Hub Carrier&Hub seem tight enough (little movement) - but still there is quite a bit of wobble/slop at the wheels.

Is this normal at this scale? Help please - it's really bugging me now
