When I slow down I can feel the floorboard knock and hear a loud clunk clunk noise and this doesn't happen enough and I can't make it happen to see exactly what it is. last month I brought it the shop in because of this same noise and found the rear passenger side axel seal was leaking and the brake caliper was sticking but before he found the caliper was bad he took off driveshaft and checked u joints and said they were tight he then realized the caliper was sticking and we thought that maybe this was the noise so rebuilt both calipers so I wouldn't have to go back hopefully anytime soon. but now the noise is back and I'm thinking when he took off the u joint maybe when he put it back it was tight and now it's messing up again and now it's making the noise a lot more frequent any suggestions? Please it's driving me crazy noise only occurs when decelerating... Sometimes loud click other times multiple clunk clunk clunks sorry for it being so long it's hard to explain sounds lol
