I noticed the other day my 2305 was squeaking/squealing from the from right tire while in slow reverse. I checked the axle oil and it was bit low, topped it off and greased all front end zerks. Took the machine out today to test and it still squeaks. I should say that only notice the noise when backing slowly in reverse with the wheel turned/locked towards the right. I can't seem to locate the source of the squeal. Any thoughts?
