Front end wobble then it goes away!

[TheClaw]

First the particulars, 2003 X5 4.4i, recent strut replacement. 95,000 miles

This morning i got a weird wobble in the front end. Felt like it was coming from the right side. I touched the brake slightly and it stopped. Then it came back after a while and in different frequencies and strength. Touching the brake this time just made it wobble a little differently.

I limped home and parked it. Started to drive it to the shop later on and....NO WOBBLE! It was very strange. It drove normally.

I'm wondering if I have a sensor that's starting to go bad? Either anti skid or the wheel speed cornering? How many sensors do I have up there?
