So the truck is an 89 with a solid front axle. I've had it a little over a year. For about nine months there has been a horrible grinding rubbing noise that sounds like it's coming from the driver side . The noise is only there when I'm moving . I've replaced the wheel bearings 3 different times now in that nine months. 2 time I did replace spindle drove 1 mile the sound was still there. Third time was yesterday I replaced the wheel hub this time cause there are signs of a spun race. Drove it about 5 miles this time. sound started again. When I do replace the bearings the sound is at higher speeds only after a month or two it's at all speeds. Last night I replaced the caliper on that side it was acting sticky on that side and not braking evenly . noise went away for probably 5 miles again. the sound is back but we are braking straight now and not pulling to the right. Could it be that i need to replace the pads and rotors as well?
The pads are uneven on that side from the bad caliper
am i headed in the right direction?
let me know what you think thanks for the help in advance!

Axle could be bent, knuckles may not be centered... just a couple ideas to think about before the gurus answer your question 😀

Could be. Haven't really done anything crazy to bend it. I can throw it on an alignment rack sometime this week to be sure though

Are you greasing your bearings by hand?

Yes

Does it happen in 2wd?

I would suggest tearing it down to the axle.  It might be the birfield rubbing inside the housing.

From a bent housing?? Or why would it rub?
