Hey I recently replaced the passenger side axle shaft and all the axle seals and bearings as well as the bronze bushing on the backside of the spindle. After a couple weeks I took the axle out to look at a differential noise and noticed the swivel ball fluid has bronze flake in it and the bronze bushing was slightly worn. I also noted there was a little more end play in the outer axle shaft at the snap ring and probably need to measure for a new spacer washer. Could that be the reason for the excessive where on the bushing or should I look elsewhere?
