Front end noise - Please help
2003 4.0 FX4
So I recently started hearing this noise from the front end. Not a knock or anything but a consistent 'whum whum whum whum whum' that increases and decreases with speed. Almost sounds like a big mud terrain tire on the highway, but off and on like stated above.
I noticed that once I put decent pressure on the brake, that it goes away. I researched that the caliper bracket bolts commonly back out, but I went under the truck and they are all tight.
However, I did notice that the caliper is loose on the drivers side. The caliper seems to have play on the slide pins. The Caliper bolts are tight as well. Would this cause the noise I'm hearing? I would think that would just create a rattle over bumps rather than a linear noise.
As far as getting the caliper tight, would new pins do the trick or are the caliper holes almost bored out and they are floating around inside the hole?
Also, I put the wheels up checked the wheel bearings and there was no play at all.
I appreciate the help in advance and really want to figure this out asap!
