I'm currently converting my 1988 F150 from 2wd to 4wd. I just pulled the TTB front axle from a donor 1988 Bronco that has sat since 2006. Nothing appears to be leaking anywhere... My question is what all would you recommend replacing??? I know it needs new rotors, pads, and I want to replace the factory hubs. But what else would you recommend or would you just bolt it up and replace stuff as it starts to wear out? Any help would be great. I looked at rebuild kits from broncograveyard.com but I really don't want to spend $800. Thanks for your time.
