i noticed a kind of humming noise coming from the front of the truck, my gut reaction is its the bearings going out. if i remember correctly its a pretty straight forward process.1. remove wheel2. remove caliper3. remove the bearing cap4. remove the spindle nut5. remove rotor and replace bearingspretty sure thats the sum of it, but do any you need any special tools? its been a while since i've done any bearing work and now i at college at my tool arsenal is basically limited to a 100 or so piece craftsman set.
You'll need a brass punch. The oil seals bearings come out easy enough but use the brass punch to knock out the races. The new bearings will come with new races. An arbor press is best to press in the new races but you can use the brass punch and carefully tap them in making sure they go in straight and evenly as you gently tap all around them in. Take your time and make sure the races are bottomed out. Pack bearing grease into the bearings before installing them. Hope this helps.
no special tools is required,a good socket set channel lock players or the right size wrench to remove the spindle nut,tap out the rear bearing cap to remove the rear bearing,you should also replace the bearing race in the router,repack the bearings with a good bearing grease then replace router.make sure you tightened the spindle nut to the right specks,not too tight or loose.also replace a new cotter pin.
