This is probably a dumb questions, but is my 87 f250 6.9 going to have manual hubs or auto?
I would think manual, but I haven't pulled the front wheels off. The reason I ask is because the wheels on it have center caps that don't allow access to the hub if it's behind that.
So, if they are manual, is there a center cap for that?
I would guess they are manual. My 89 has manual hubs, not sure if they offered auto hubs then. but if they are covered by your center caps that's not going to work too well, unless you want to keep them locked all the time. Not good for gas mileage.
It's definitely four wheel drive, but the wheels were put on it temporarily by the previous owner and then it sat and they ended up staying on it. I am thinking I'll use a hole saw to cut out the center of the caps if it doesn't look to tacky otherwise i'll leave them off.
Okay, so I pulled the wheels and they are manual hubs. So I pulled the center cover out of the wheel and I'll drill out the center to allow access to the hubs.
I tested it, and its a night and day difference too.
