It's not a dumb question, it's a dumb design. :) DC used thin wall tubes and only pressed them into the pumpkin with half assed plug welds to keep the tube from rotating. Jacking from the diff can bend the axle assembly taking the bearings and seals out of alignment just enough to cause excessive wear. Older thick wall steel (welded) axles didn't have that weakness. -- DougW |
