Recently installed a rebuilt Ruckstell axle in my ’26 roadster and after approx. 60 miles I checked the oil and found fine bronze particles suspended in the oil. (using 85w - 140w) Should I be concerned? Recommendations?
Enlarged photo shows minute bronze particles in oil.
If it were me, and the axle runs quiet and shifts fine, I would change the fluid and check it again in another 60 miles.
Ruckstell does run quiet and shifts fine. No unusual noises. Center housing gets slightly warm after a drive.
