Hey guys I am new to the forum and this is my first post so bear with me. I have a 1999 F150 with a 5.4 and 8 out of 10 times I go to hit the brakes it starts making a grinding noise. It starts at around 20mph and continues until about 4-5 mph then makes a very loud clunk/ bang that shakes the entire truck. I can feel it even if I have my stereo way up. After I take off the truck continues so make smaller clunking noises wile I accelerate. The truck never makes any noises wile at speed even during hard acceleration as long as its not from a stand still. I have tried putting in a new CV axel assembly because my old one had a large tear in it. I did not fix the problem and want to get some input before I go throwing more money and parts at it.
