- Description:
This is a genuine Ford rack and pinion mount bolt, a large M16 by 232 millimeter shoulder bolt that secures the steering gear, also called the rack and pinion assembly, to the front subframe or crossmember. Ford dealer catalogs list it under several names including Rack and Pinion Bolt, Gear Assembly Mount Bolt, Mount Bolt, and Shoulder Bolt, and it appears in the steering gear and linkage diagram as a required mounting bolt. It is the longer companion to the shorter rack mount bolt used at the opposite side, and its shoulder design locates the steering gear precisely and clamps it firmly so the rack stays rigidly mounted, which is essential for accurate steering response and safe control. This is a single-use fastener: it must not be reused or reinstalled once removed, and a new bolt must be fitted whenever the steering gear is serviced so the correct clamp load and thread integrity are restored. You will find it used on Ford applications including F-150 and Expedition, and it fits Lincoln Navigator, across several wheelbases and engine options including 2.7L, 3.0L, 3.3L, 3.5L, and 5.0L, in the front left mounting position, with model years spanning roughly 2015 into the mid 2020s. These are representative examples rather than a complete list. A loose, missing, or reused-and-stretched rack mount bolt lets the steering gear shift, which causes a knocking or clunking through the steering, vague or wandering steering feel, and is a serious safety concern. Because this is a torque-sensitive, single-use steering fastener, always replace it with the correct genuine bolt and torque it to the Ford specification. Confirm the correct bolt for your specific vehicle against your VIN before ordering.
- Notes: Part cannot be reused/reinstalled.
