2002 front dif noise?
I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad and I have no idea what it is. I am very mechanically inclined but cannot figure it out. Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around.... If anyone has any ideas what could be wrong it would be greatly appreciated, thanks!

have you check the gear oil level in the front diff?

It's not the ball joint or the end links. And I was thinking maybe there could be a bearing or something where the axle does into the diff that could make a noise if its wore out, every time the suspension moves the axle moves up and down
