Rear Diff/Axle for Shuttlebus

As Team Faith has expanded ministry opportunities - now on Areanacross, GNCC and Watercraft Racing - the road miles have taken a toll on the vehicles. Recently, Chuck was traveling from an FCA dirt bike camp in Indiana to another camp at Muddy Creek, TN and the rear end blew apart on the shuttlebus! It is currently parked in Knoxville, TN.  Unfortunately, this is the 2nd rear end that we've gone through. Our best option at this point is to replace with a remanufactured differential from Jasper Transmissions. The cost is about $2,750 plus $750 install. Used rear ends are about $2,000 (plus install labor) and you don't know what you get. To rebuild the current one is also $2,000 + labor and no warranty.  The Jasper option has an 18 month warranty AND they can gear it to our specs (4.10 instead of 4.63). The biggest downside is that it takes money! We are asking our friends and supporters to consider helping out as we try to get this vehicle back on the road in time for the 2nd 1/2 of GNCC (September 5 - 7). Thank you and God Bless!
