My son asked to borrow my car. He says he was driving when someone ahead slammed on the brakes - he didn't hit the car but turned it sharp to avoid a collision. In doing that the front driver tyre is stuck and won't move. I haven't seen it as he's about 13 miles from home. He thinks something has snapped off. I know it's not much to go on but say the whole front axle needs replaced, how much would it be to supply and fit (if I use a Vauxhall garage)?
