A noise and steering question. Mike hears a 'whup whup whup' noise, gets faster as car goes faster, changes on right turns. Seems to be coming from left front wheel area. Mechanic replaced half-shafts, didn't help. Tom and Ray think he's got a bad tire--may be tread separation. Try two new tires, noise should go away. Could also be wheel bearing.
