Front Control arms

Hi,

Can anyone tell me how much movement is there is suppose to be on the rear bush of the front control arms?

I have noticeably more play in the passengers side than the drivers while what seems a control arm/wishbone problem from previous experience (and it's prob the cheapest of what I think the problem could be too!). Just trying to work out what to order from GSF with my 15% off (coupon on there website for your local branch)!
