Before I traded her, I had a 1998 Ranger 4X4 5 speed 4.0L OHV. 200k - I rebuilt the trans and rear end, bushings, ball joints, shocks, and 1 battery. It had no leaks at all not even from the valve covers, original hoses, water pump, alternator, radiator and pretty much everything else underneath the hood was still factory. It's all about the maintenance, and how you drive it.
