What would cause metal shavings to be present in the rear-end fluid?
I have over a million miles on my 1994 W1A64T and at the last service, I noticed metal shavings on the fluid fill plug of the back rear-end. I would like to know what would typically cause the shavings, and if I need to replace the rear end or if it just needs some new bearings.
I am going to have the rear-end looked at today by a technician for their opinion, and every little bit of information helps.
I would also like to know if anyone has experience using a vehicle equipped with MicroBlue-treated bearings in the rear-ends.
Jack and Jackie, thanks for the answers. I will be watching that rear end closely and will be getting it rebuilt or replaced soon.
Ron, the problem was so obvious the mechanic just took one look and figured it out. Jack and Jackie had the correct answers for the problem. We didn't even need to send the fluid to a lab to figure out the root cause.
Is this a good question?
