Re: 1990 Blazer front brake disc change anybody? H
It's not a bad job when the weather is nice. But when it's cold out it isn't much fun. And I know what it's like to work on my truck when it's cold out...
You could take it to one of those fast brake shops and see how much they'll charge you. It'll probably be around $120+parts if I had to guess and then they'll try to charge you more because they didn't know it was so labor intensive. Most people have never done the work before because those axles were out of production when most of those grease monkeys were still in gradeschool.
It's a chore to do if you don't normally do it. You've got a lot of work to disassemble and reassemble the hubs. I know people that can change axleshafts in 35 minutes so I know it can be done fast, but most people aren't that fast. It takes me about an hour by the time I take it apart, clean all the parts, change the large seal, grease it up, and reassemble.
I'd call around then get a written, formal, estimate. That way they can't take you to the cleaners.
