Not sure if I'd buy parts just yet, the problem maybe due to some corrosion of metal parts, or thickening grease. Get a manual and see how it goes together, or do a search online. As you have a popular truck so it shouldn't be hard to find info or even step by step procedure w/ picts. Sure you brother would have no problem fixing it. luv my '93 22RE, 4x4. had it since new, 124K, one clutch, one caliper, water pump, clutch, A/C. One set front pads due to sticking caliper.
