CHecking WIshbone Bushes Help

[Surf_MoFo]

i have steering wheel vibration when i brake, i have replaced the steering rack bushes but its still there, the brake discs are true, i have found a slight bit of play on the drivers side lower balljoint but i dont think thats enough to cause the steering wheel wobble, i could be wrong.

i have found lateral movement in both sides wishbone bushes, in not sure what is acceptale but the inner wishbone can be easily moved using a long pinch bar. will i need to take it to a garage to get checked properly as this play may well be acceptable as i am unsure how to judge it.
