Chevrolet Avalanche 1500 Pinion Bearing Parts Questions & Experts Answers
Q: What tools are required to replace the drive pinion bearings on a 10.5-inch axle on Chevrolet Avalanche 1500?
A: A replacement of drive pinion bearings on 10.5-inch axles requires these specific tools: pinion oil seal installer-rear (J22388) and Differential side bearing installer (J22761) and split plate bearing puller (J22912-01) along with pinion cone and side bearing installer (J24433) and Pinion Bearing installer (J37624) and universal driver handle - 3/4 inch - 10 (J8092) combined with rear Pinion Bearing installer (J8608) and flange and pulley holding tool (J8614-01). Begin by elevating the vehicle then unfasten the Differential assembly and subsequent pinion gear bearing retainer followed by pinion yoke and oil seal. A hydraulic press and split plate bearing puller (J22912-01) will allow users to remove the outer and inner pinion bearings. Examine the bearing cups by hitting them with a hammer and brass drift. Start by mounting the pinion gear pilot bearing onto the permanent component of the Pinion Bearing assembly with j22761 Differential side bearing installer. Then use Pinion Bearing installer j37624 alongside universal driver handle j8092 to install the inner Pinion Bearing cup correctly. To install the outer Pinion Bearing cup selects the rear Pinion Bearing installer (J8608) together with universal driver handle (J8092). The process continues with installation of the inner Pinion Bearing using the pinion cone and side bearing installer (J24433) onto the pinion. After inserting a new collapsible spacer you must lubricate the bearings before placing the outer Pinion Bearing into the retainer. After installing the new pinion oil seal using the pinion oil seal installer-rear (J22388) complete the process by inserting the pinion into its bearing retainer. Use sealant gm p/n 12346004 or canadian p/n 10953480 on the pinion yoke splines before installing the yoke onto the pinion shaft through soft-faced hammer impact. Proceed to tighten the pinion nut using the flange and pulley holding tool (J8614-01) until the pinion end play reaches its limit point while twisting the pinion. Use j8614-01 flange and pulley holding tool to install either the original shim or a new shim of 0.41mm thickness when the original shim cannot be used. The axle housing must receive the pinion gear bearing retainer with its retainer bolts adjusted to 88 nm (65 ft. Lbs.) before checking the pinion rotation torque at 1.0 - 2.3 nm (10 - 20 inch lbs.) for used bearings or 1.7 - 3.4 nm (15 - 30 inch lbs.) for new bearings. The pinion nut needs additional tightening in small increments until it reaches the required torque values. Verify the specified torque on the pinion then apply several resulting movements to ensure bearing seating before rechecking the torque and making additional adjustments if required. Following this procedure involves putting the Differential assembly back in place while adjusting the Differential side bearing preload and setting the drive pinion selective shim thickness and backlash adjustment and filling the axle with lubricant and finally lowering the vehicle.
