Description
The Ford 10.50-inch rear axle assembly is an integral type housing, hypoid gear design with the centerline of the ring gear set below the pinion centerline.
The hypoid ring gear and pinion consists of a 10.50-inch diameter ring gear and an overhung drive pinion. The pinion is positioned by selected pinion shims and supported by two opposed tapered roller bearings. Pinion bearing preload is adjusted by the pinion nut and a collapsible spacer.
The rear axle housing consists of a cast center section with two steel tubes and a stamped steel rear cover. The differential housing cover uses a silicone sealant as a gasket.
The differential case is a one or two-piece design depending upon the application. The differential pinion shaft in the one-piece differential case design (2-pinion) is retained with a threaded bolt. The two-piece differential case 3-pinion spider is retained by the case halves which are bolted together.
The rear axle drive pinion receives its power from the engine through the transmission and driveshaft. The drive pinion rotates the differential case through engagement with the ring gear, which is bolted to the case outer flange.
Inside the 2-piece differential case, three differential pinion gears are mounted on a three-post shaft. Inside the 1-piece differential case, two differential pinion gears are mounted on a straight shaft. These differential pinion gears are engaged with the differential side gears to which the axle shafts are splined. Therefore, as the differential case turns, it rotates the axle shafts and rear wheels. When it is necessary for one wheel and axle shaft to rotate faster than the other, the faster turning differential side gear causes the differential pinion gears to roll on the slower turning differential side gear to allow differential action between the two axle shafts.
The 10.50-inch rear axle uses SAE 75W-140 High Performance Rear Axle Lubricant F1TZ-1 9580-B or equivalent meeting Ford specification WSL-M2C192-A.
