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!

Need more specifics on a modified rig.

brake set up? Most run IFS calipers and LC rotors. Could be stock set up or IFS rotors and calipers.

Have you checked run run out on rotors?
clips rubbing?
have you checked fluid? Color?
flushed lines?
Is there a line-loc installed?
do all caliper pistons compress freely?
can you recreate noise with wheel off hand turning hub?
brake pad shim rubbing hub?

it is ifs calipers and vented rotors from trail gear. Fluid is good and clean flushed yesterday when I changed caliper and bread brakes. I'll have to check runnout later and no I cannot recreate sound turning it by hand

did you set wheelbearings to factory spec or any of the others out there. How was grease on old wheelbearings? Hard to tell if you use black colored grease but it you used red or green easier to tell. Are you using bolts or studs to hold spindle on? Are there and wear marks on inside or outside of rotor?

not trying to sound snutty just spitballing to see what you've done.

grease on old bearings was put in green but was black now . Wheel bearings I use a fish gauge to help set preload until I have 18ft pounds of drag. Start by torquing preload nut to 43 rotate both ways loosen rotate torque rotate loosen rotate torque rotate final torque for the drag is usually around 4 ft lbs. outer lock ring torqued to 47. I'm using bolts on spindle.
i feel like the wear marks on the rotor are normal but maybe I'm wrong just lines running the length all around the face.

low range Offroad has a different method for setting wheelbearings pre-load, don't remember if it's 23lbs or 28lbs. You can watch vids to get exact. So far I've had good luck. 4lbs just sounds low expecially with 35s. If the green grease is Lucas xtreme duty it's good stuff and water proof, has a temp rating for wheelbearings. Lucy's site says it's normal to darken when heated. I used it last rebuild. I had to swap calipers last week just re-used pads. Shims on back of pads were rubbing hub so I just ground on them a little.

93RedKrawler

whatdo you mean by shims on the brakes rubbing?

whatever set of pads I got last time had shins mounted to caliper side. Think they're supposed to quite pads. Have also had wear indicators rub too.

how muck play is in bearings with tires mounted?

Ok gotcha. And an eight of an inch or less
