Well my mom has an 04 explorer 4X4 XLT and has a clicking sound when you are slowing down to a stop or accelerating from a stop. It will do it turning or going straight. She took it to a reputable shop that looked at the breaks and all the suspension. I'm guessing they took a look at the CV joints since they looked at the suspension, but everything came back ok, except the brake pads had cracks in them. I wouldn't think that would cause a clicking noise though, especially while she is accelerating. Well the clicking is getting louder and I'm having her go back to have the u joints checked and checking the fluid on the transfer case just to be safe. I don't know what else it could possibly be. Does anyone know of anything else that could possible make this clicking noise?
