+1 one pal, get it checked out, also look for uneven wear one the tyre bud, if its the wheels, get new set of better wheels dont bother fixing buckled ones, if its prop shaft then get it sorted quick
ill get that checked out
but i just realised i got my locking wheel nuts busted cos i lost the key. so i have a nut missing from each wheel.. ill get those first before splashing out on a proper check
sounds reasonable?
