Jim, We just got our brakes done on a 2002 with 60K miles. Longo Lexus did not mention anything about repacking bearings. I have to assume they were not done or the outside ones were done as you had described. Is this something we should worry about and have the inside ones done, will it cause damange? Thanks.
No, but I'd at least recommend having the rotors turned. New, quality aftermarket rotors like brembo's or powerslots run about $105-120 each. Pads are about $50/axle for OEM. They should replace and regrease the anti-squeal shims (about $40 per axle). If you just slap new pads in, chances are, the brakes will start pulsating due to the new pads not distributing pad material evenly on the worn (not flat) rotors.
The rear rotors are easy to do...maybe 15 min each wheel. Fronts are a different story, as it's 4wd. You need some special tools...large brass bar and hammer, snap ring pliers, 54mm 6-point SST socket, fish-scale for tension, torque wrench, 17mm deep 6-pt socket, misc other sockets. You need to remove the wheel, brake caliper mounting bolts and hose bracket bolt (don't disconnect brakes hose). Then remove the dust cap, 4wd flange (use brass bar and hammer to pound the 6 studs). With the flange off, remove old gasket, then use snap ring pliers to remove snap ring. Use large screwdriver to bend tabs on aluminum lock washers back straight, then use 54mm socket SST to remove outer and inner axle nuts. Remove hub & rotor unit, unbolt rotor from hub, replace w/ new rotor. If you haven't repacked the inner bearing, do so now. Use a seal driver, plastic hammer, or stack of wood to set the brass seal for the inner bearing. Repack outer bearing and torque inner nut to the spec'd torque, turn wheel back & forth, loose nut, tighten to new torque, then install lock washer and outer nut. Use fish scale to test tension on lug nut. Reinstall snap ring, then 4wd flange. For each wheel, you'll need one inner oil seal (~$22), a new aluminum lock washer (~$5), a flange gasket ($2), plus grease. A bearing packer helps. Figure about 4 hrs to do the job if you've done it before, 8 hrs if you haven't. Labor is typically $250-300 for a front bearing repack, so I'd figure that much to install rotors up front alone. I glossed over the steps just to give you an idea of how labor instensive it is, and how, if you can get the dealer to do it for $200 in labor, it's a steal. :-) It's a labor intensive, messy job that no one wants to do, even for a pro. BTW, you are supposed to repack the front wheel bearings (in the above method) every 30K mi.
