My truck was sounding like a semi on the highway. I checked rear diff and was low. No fluid dripped out and could not feel with finger.
No signs of a leak?? I added gear lube as best I could. Real mess.
Location of fill hole is horrible. Any one have a good way to add fluid here?
I have a collection of dispensers, like condent dispensers in a diner, transfer fluid to dispenser, attache hose and fill differentials. Lot of other uses, but small enough to manuever up into frame to get to hard to reach fill poorts.
