OK, so it looks like I've managed to make the easiest job into a project. I purchased rebuild kit from NAPA (PN #1525). Replaced the seal but cannot get the dust boot in. I lubed it with brake fluid and slipped it over the piston so just the rear flange area which goes into grove in caliper is showing. It seems like it's simply too large and will not fit. If I get it in 90% around, there's way too much excess material to slip in. Not going to happen. I ended up tearing one and installed it without the piston. It ended up with about 3/8" overlap so I started thinking I had the wrong part even though the seals went in easily. I purchased a second set from Rock Auto which turned out to be NAPA brand. Same thing. I reused the old dust cover on one side but the other side is too far gone to use. The diameter of the flange if definitely larger in the NAPA seals than in the old ones.
I have watched "how to" videos and did the rears with no problem. Is there some tribal knowledge I'm missing? Maybe the NAPA brand doesn't fit right?
