My neighbor has a 1998 F150 4x4, V8 engine(not sure the size).The problem is
that when he turns left or right, in 4 wheel drive, it makes a metallic,
loud, clunking sound from the left front side. When driving forward in 4x4
it doesn't make quite a loud noise as when it turns. (still makes noise
though) I had him back up in 4 low and I stuck my head in the wheelwell to
listen and I THINK it is coming from the axel shaft itself.
Could this be the axel joints wore out on this side? The other side does not
make any noise.Does this problem effect the vehicle in 2 wheel drive? I told
him it didn't. Might be wrong though.
