My 2015 Fitzgerald Glider had to have the main bearings replaced at just short of one year due to wear metals detected in my oil samples. Less than one year later my sample detected wear once again. My Detroit shop was at a loss as to why it was doing this. They eventually figured out that the wrong size bearings were put in the first time they were replaced. The shop ran the engine serial number to get what they thought were the correct replacement parts but something had been changed in the rebuild. After Fitzgerald and Detroit figured this out they agreed to split the cost of the work.
