I had my SP 500 out in the snow over the holidays, just driving up and down the gravel roads. I noticed a clicking type sound from the front end somewhere, for what seems like every revolution of the wheels. It's most noticeable while doing about 15mph steadily. It sounds the same in both 2wd and 4wd. I never noticed this driving on the dirt roads before the snow. Maybe snow muffles the tire noise? Anyway, I just wondered; haven't decided if I need to take it in to the dealer. Thanks.

 

My TBlazer does that, and upon further investigation I found that its just the brake pads moving back and forth along the disc.
