Some Traxxas customers have recently reported serious differential failures with their Traxxas Revo trucks. Our engineering team has investigated the failures and has determined that some Revos were built with defective differential output gears. The output gears were manufactured smaller than the engineering specifications. This causes the gear mesh inside the differential to be extremely loose, and results in premature differential failure. The spider gears are manufactured correctly; however, the incorrect internal mesh will likely cause them to fail along with the defective output gears. The ring and pinion gears are manufactured correctly and are not experiencing failures.
We are currently investigating to determine the exact number of trucks that have been produced with the defective differential output gears. Please bookmark this page and check back in 24 hours. We will be posting more information as soon as it becomes available.
