Each Ford F-150 model is equipped with an axle code located on the rear axle cover. The axle code indicates the gear ratio specific to your truck, tailored for various driving scenarios. Different gear ratios are optimized for on-road, off-road, or towing purposes. For instance, an axle code of 27 on your F-150 signifies a 3.31 gear ratio with an open differential, ensuring power is distributed to the wheel with less resistance. While this ratio is suitable for city driving and light towing, it may not be ideal for extensive off-road use, where a locking differential is preferred to help navigate challenging terrains and prevent getting stuck.
The Axle code 27 on a Ford F-150 corresponds to a 3.31 gear ratio, while "19" signifies a 3.55 gear ratio for the vehicle.
On the right side of the back axle, there's a label. My vehicle is a 2016 model with a 2.7-liter engine. The label indicates "8.8".
I drive a Ford F150 with Axle code 27 and I need to replace the left rear axle shaft which was damaged in an accident. I have a choice between an 8.8" or a 9.75" axle shaft but unsure which one to get. It seems that the 9.75" is meant for the larger 3.5L version of the truck, while my 2.7L Turbo version might require the 8.8" axle shaft. My truck is a 2015 F150 XLT 4 Door Crew Cab 2.7L Turbo, V6 with Ecoboost Rear Wheel Drive with Axle Code 27 on the door label. I'm considering using calipers to measure the bearing or shaft diameter to be sure before making a purchase.
