after 9 months i had altenator replaced under warranty, after battery light illuminated. all fine and dandy untill just b4 xmas when the steering felt a little unusual. when i first set off in a morning, reverse off the drive then pull forwards, the drivers front wheel feels like its on the rim like i have a flat tyre, then when i straighten up its ok. steering just feels little light when driving what cud this be? ive seen problems like wheel bearings and driveshafts cud this be it? or a power steering problem? and if so how much we talkin to mend it???
