When I first got my Bronco 35+ years ago I had issues with Master cylinders for the front manual drum brakes went through them every 2 years until I went to disc brakes up front. Then my 1974 with its smog pump and odd ball waterpump would go through a water pump every 15,000 miles or so. I use to buy my rebuilt stuff from Ford but it just didn't last like they should. Motorcraft starter solonoids only lasted about 3 years or so when I was daily driving. About 15 years ago I switched to buying Napa's better stuff and these issues went away. I also havent daily drove my Bronco for the last 10 years or so. I've had my Bronco since Christmas Eve 1977 and its been a pretty darn reliable rig. At least the things I have needed to buy have been cheap compaired to these newer cars where I have to spend 50-100 bucks on just a sensor to keep it alive.
