A lot...
All within the past 10K... alternator, water pump, thermostat, serpentine belt, driver side power window motor, radiator and some more little stuff. Oh, drive shaft came off!
Lots of electrical problems, but they were my fault b/c I messed up the compact disc player installation.
Overall I love my truck. When it goes its tough, the 4WD kicks, but, and I've only been stuck twice, and that was in a ditch, and in a 3 foot deep mud hole where I bottomed out. I took off all my piping after the second catalytic converter and this guy rumbles!
Acceleration sucks, but you gotta trade something for raw power (I pulled our tractor out of the ditch once in 4 low).
I have a 5th leaf spring in the back so the back rides high, and I can hold extra loads. Defineately a good thing to have.
Overall, when this runs, which it will for about 4 weeks before something goes, I love this truck. Overall its great, and I'm a little hard on it around the house and mud, so take that into consideration too.
Hey your truck doesn't sound too bad. I have a 89 f-150 and the only problem I have had is some electrical.
My acceleration is awesome. maybe it is because mine is a 2 wheel drive. Mine can beat some rice burners.
I also own a 1989 Ford F150 Lariat. I have had ongoing problems with my charging system surging overcharging the battery.
