This is what the pros at the White City Boyz shop found when they cracked open our axles. Nasty. It looks like our axles were never taken care of and maintained. Judging from the grease there was water contamination and years of grit and grime imbedded in it. Truck and buggies that see a lot of mud and water should always have their axles cleaned and maintained and packed with fresh grease. A little maintenance goes a long way.
