Cadillac Escalade EXT Pinion Bearing Parts Questions & Experts Answers
Q: How to replace the drive pinion bearings on a 10.5-inch axle on Cadillac Escalade EXT?
A: The drive Pinion Bearing replacement task for a 10.5-inch axle requires Differential side bearing installer (J 22761), flange and pulley holding tool (J 8614-01), Pinion Bearing installer (J 37624), pinion cone and side bearing installer (J 24433), split plate bearing puller (J 22912-01), rear axle pinion oil seal installer (J 44414), rear Pinion Bearing installer (J 8608), and universal driver handle - 3/4 in - 10 (J 8092) as tools. Start by elevating the vehicle to access the Differential assembly accompanied by the pinion gear bearing retainer and yoke before extracting the oil seal along with both pinion bearings and the pinion with collapsible spacer. A hydraulic press working with the split plate bearing puller (J 22912-01) will help remove the inner Pinion Bearing and both bearing cups need extraction with a hammer using a brass drift. The installation of the pinion gear starts with the pinion gear pilot bearing installed by a Differential side bearing installer (J 22761) after which the inner Pinion Bearing cup requires installation by using the Pinion Bearing installer (J 37624) with universal driver handle - 3/4 in - 10 (J 8092) then follow it with the outer Pinion Bearing cup using a rear Pinion Bearing installer (J 8608) with universal driver handle - 3/4 in - 10 (J 8092). Proceed with inner Pinion Bearing press operation using the pinion cone and side bearing installer (J 24433). Then install a new collapsible spacer followed by lubricating the pinion bearings before inserting the outer Pinion Bearing into its retainer. The rear axle pinion oil seal installer (J 44414) installs a new pinion oil seal after which the Pinion Bearing retainer receives the pinion with sealant application (GM P/N 12346004 or Canadian P/N 10953480) to the pinion yoke splines before alignment and installation. Apply torque to the pinion nut using while holding both the flange and pulley holding tool (J 8614-01) until the pinion end play reaches the desired limitation while performing constant pinion rotation during tightening. When the flange and pulley holding tool (J 8614-01) is removed, install either the original shim or a 0.41 mm high (0.016 inch) shim when the original shim is not available before attaching the pinion gear bearing retainer to the axle housing while tightening the retainer bolts to 88 nm (65 ft. Lbs.). The rotating torque measurement of the pinion should range from 1.0 to 2.3 nm and 1.7 to 3.4 nm (10 to 20 inch lbs and 15 to 30 inch lbs) depending on whether you work with used or new bearings. Use the flange and pulley holding tool (J 8614-01) to tighten the pinion nut while checking torque values until reaching proper specifications. When you achieve the predefined torque you must repeatedly rotate the pinion spindle to allow bearing proper seating followed by torque check and optional adjustments. The procedure ends by re-installing the Differential assembly while making preload adjustments on the side bearings and determining and installing the appropriate drive pinion shim thickness before setting backlash and filling the axle with lubricant before lowering the vehicle.
