F250 350 F350 450 F450 Differential Yoke Yukon Gear & Axle YY F100609

Yukon Gear & Axle pinion yoke / flange — F250 350 F350 450 F450. This is a build component selected by SPECIFICATION rather than by a single vehicle application: match the frame size, flange, wheel size and A/R to your build. If you are not certain what your build needs, ask a tech before ordering.

What it does

The yoke is the joint between the driveshaft and the pinion. A worn yoke lets the u-joint move where it should not, which shows up as driveline slop and a chewed pinion seal, and the factory part is often the weak link once a bigger shaft goes in. A new yoke restores a tight, sealed driveline joint.

How to choose

• Match the compressor and turbine wheel sizes to your power target and drive style
• Match the turbine housing A/R and flange to the manifold and downpipe you are running
• Confirm the oil and coolant feed arrangement matches your engine
• Check the part number against the component you are replacing

Fixes

• driveline clunk or slop on throttle changes
• a leaking pinion seal from a grooved yoke
• a driveshaft upgrade needing a matching joint size
• worn u-joint bores

What's included

• the yoke or flange at the joint series and spline count stated
