If you have a favourite general garage they could have a look and may be able to check/adjust tracking.
If not, tyre depots ,especially those that also does mot's and general repairs, often offer free safety checks on tyres,suspension and brakes etc .
But be careful.They only offer free checks because they are hoping for repair work,so your free check,and all those they do on cars that didnt need work, often means higher prices for work that may not really be necessary. This can also be true of ordinary garages of course.
Check out your local tyre depots on line to see what they offer.Then visit a few. You'll soon spot the cowboys.Eventually you'll find one with nice blokes who take an interest in your car and are willing to go that bit further to help.
If you go during the week,mid morning or mid afternoon they may have more time to chat
