Default Thump..thump..thump


My wife has an '01 Elantra with 78k on it. It keeps on having a thumping noise coming from the front end (drivers side). Mainly at highway speeds (50-65mph).
So far we've replaced the wheel bearing, and the brake caliper and pads (master cylinder locked up cause it was faulty). I did try a new drive shaft, and it did the same thing.

When the master cylinder locked up, could it have slightly warped the rotor? (she did drive it about 5 blocks with faulty cylinder) Would this cause the thumping noise in question? My impression about a warped rotor was that it affected braking, i.e. pedal moving up and down when braking. Would a warped rotor cause a thumping noise at highway speeds?

I am at a loss here. I don't know what else to do.
Anyone have any suggestions?
