Ford’s turbo failure

During a detailed teardown of a 2011 Ford 6.7L Power Stroke, Gale Banks revealed the secrets behind their innovative turbo. Garrett’s single-sequential turbocharger featured an industry-first double-sided compressor wheel mounted on a single shaft. Turbocharger failures were common on 2011 and 2012 model year 6.7L Power Stroke-equipped pickups because of weak ceramic ball bearings. A switch was made to steel ball bearings. Unfortunately, it wasn’t enough to keep this turbo in production. Ford opted for a single-wheel compressor for the 2015 model year.
