Newb question regarding auto hubs
Hi, I am a visitor from the Jeepster board. I am a GM newb, so I was hoping to pick your brains a little.
I just bought a '84 4x4 diesel Suburban to use as a tow rig. Itís a ĺ ton and has the 208 t/c and auto locking hubs. I was wondering if there is a big advantage (especially in terms of MPG) to changing the auto hubs over to manual hubs. When working properly, the auto hubs are supposed to allow the front to freewheel, right? If so, the manual hubs wouldn't provide any mileage advantage over properly functioning automatic hubs. Am I correct on this?
Do the auto hubs have other problems I should be aware of (i.e. are they weak and/or do they have problems engaging/disengaging)?
