A few days ago I was replacig the front brakes on my '94 Dodge. When I went to tighten up the caliper bolts, one of the bolts wouldn't tighten, so I took the caliper back off ad discovered that I had tore the threads on the steering knuckle (thats what Haynes calls it) all up. The bolt would tighten enough that the caliper won't move, but I was wondering, has anyone replaced the knuckles on their car? Also I was wondering how much time should I set aside for this project, and how much is this going to set me back? I usually do my own maintenance, but I've never done anything this involved, especially on a front wheel drive. Any comments or suggestions would be greatly appreciated. Thanks.
