I had similar problem when coming to a stop. I have a 2003XLT 4X4. Chatter with a swoosh sound & wondering if I was going to stop. Took to garage where I've done a lot of business. Said he couldn't find problem. Sensors good, according to him, and no ABS light. Anyway driving under those conditions was nerve racking and I looked for another answer. Long story short neighbor mentioned my problem to a friend that does his work and right away he said ABS. Took it to him and the problem was fixed in one evening. One sensor he cleaned, had accumulated a bit of rust, and he replaced the other because it still acted up. Put used one in that he had on hand and cost me $120.00 for total work. Running fine. Former garage I have lost faith in and he has lost my business...Was looking for a later post on same subject where someone suggested booster. Wanted to thank him for the suggestion but it was the ABS.
