I keep replacing starters in my truck. I've had this truck for 8 years and have put 89k on it. Truck total has 189k on it. Seems like ever 2 years I go thru starters for it. I'm thinking it's due lack of driving it. It may do sit for weeks with out starting. I started it up the past weekend turned over just fine. Batteries are good and solenoid clicks. Is not driving it possible why I go through so many? I have a friend with a excursion of same year. We have had ours for almost the same years and he hasnt replaced a starter yet. What should I check for to get better reliability? What starter should I purchase?
