Yukon Gear Flange Yoke For Ford 7.5in Truck (5in OD)
A Ford Ranger, Bronco II or Mazda B-Series pickup with gear oil dripping from the front of the rear axle, or a clunk every time you let off the gas, often needs more than a pinion seal. The Yukon Gear and Axle YY F750602 is a replacement pinion flange for the Ford 7.5 inch truck rear. Instead of the U-joint ears found on a yoke, it has a round companion flange measuring 5.0 inches across, and the driveshaft's rear flange bolts flat against it. The bore has 28 splines to match the 7.5 inch pinion.
On the small Ford trucks the rear of the driveshaft ends in a flange rather than a bare U-joint, so the pinion carries a matching companion flange. It slides onto the pinion splines and is clamped by the pinion nut, which also holds pinion bearing preload against the crush sleeve. The hub of the flange is the surface the pinion seal seals against. Because the 7.5 is a light-duty axle that often sees oversize tires and towing in Rangers, the hub picks up wear, rust pitting and spline looseness with age.
Mark and unbolt the driveshaft from the flange, then check the flange by hand for any back-and-forth play on the pinion. Clean the hub where the seal rides and look for a groove or pitting. Measure across the flange: this part is the 5 inch OD version, so confirm your driveshaft flange matches. If the pinion bearings have play, or the axle is whining, the flange is only part of the fix and a Ford 7.5 master overhaul kit with new bearings, races, a pinion seal and a crush sleeve is the complete repair. If you would rather source the bearings separately, the Timken Ford 7.5 rebuild kit covers the bearing side of the job.
Yukon lists this flange for the Ford 7.5 inch rear in the 1983-2011 Ford Ranger (2WD and 4WD), the 1984-1990 Bronco II, and the Mazda B3000 and B4000 pickups from 1994 through the late 2000s. The 7.5 inch rear was also used in Mustangs, Aerostars and other Ford cars, but this flange is listed for the truck applications only, so do not assume it fits a car. Check that your pinion has 28 splines and your driveshaft uses a round flange of this size, or send us your year, model and VIN and we will match it.

Yukon lists the 1983-2011 Ford Ranger, 1984-1990 Bronco II, and Mazda B3000 and B4000 pickups with the 7.5 inch rear. Confirm 28 pinion splines and the 5 inch OD flange on your truck.
It is listed for the truck applications only. Ford car and van versions of the 7.5 can use a different flange or yoke, so send us your VIN before ordering for a car.
The seal rides on the flange hub. If the hub has a groove or rust pitting, the new seal cannot seal against it. Replacing the flange and seal together fixes that.
No. On a crush-sleeve axle, tightening the nut past the original setting over-crushes the sleeve and preloads the bearings too much, which leads to whine and bearing failure. Restore the original rotating torque or rebuild the pinion.
A new pinion seal and pinion nut at minimum. If the bearings are worn, a Ford 7.5 master overhaul kit includes the bearings, races, seal, crush sleeve and pinion nut.
