Question: Please noterespond to issue below

had front & rear axle fluids changed @ 30,000, and now @ 38,000 am told by another facility that the rear differential fluid is "dirty/contaminated" needing service. Is this a different issue?? Also your service minder states the "crankcase" fluid needs to be changed at the current mileage.. Please help me with this confusing terminology...

Thank you...

Rear axle fluid and rear differential fluid are the same thing. It is possible the 2nd shop is going by the mileage and didn't check the fluid itself, or it is possible that they did check the fluid and there is a problem. Did you tell them it was just replaced? Ask to see the fluid yourself and get their version of the cause of contamination is. Or go back to the 1st shop and ask them if anything is wrong with the fluid.

Crankcase fluid is engine oil. Hope that helps.
