Ticking sound from rear of car
 
I have a 2002 WRX and accidently washed out the wheel bearing grease with WD40, one bearing (rear left) developed a whine during a 1600km round trip and shortly after a ticking developed that appears to be coming from the rear right.

Yesterday I had all 4 wheel bearings replaced and after about 20 minutes the ticking sound seems to have returned, it gets faster/slower according to the speed of the car. When I first heard it I thought there was a tech screw in the tyre as it sounded like it's making that ticking sound every rotation.

Its driving me nuts and is the main reason why I spent about 1k to replace the bearings, any idea what this sound could be?

Wheel weight? I had one come loose, sticky adhesive stuff lost its stick, but it had enough stick at one side to make it [I]appear[/I] to be on the rim, but when in motion it was flapping about..... at each revolution of the wheel.... tick... tick... tick... tick...

centrifugal force would keep it in place at all but very slow speeds - ie roulette wheel

It was a rough edge on one of the front pads making contact with the slotted rotors.

Just a quick buff on the long edges of the pads with a bench grinder fixed it.

Cheers everyone for the input.
