Chevrolet Trailblazer Pinion Bearing Parts Questions & Experts Answers
Q: How to replace the drive pinion bearings on Chevrolet Trailblazer?
A: The drive Pinion Bearing replacement process requires specific tools which include j7817 (Outer Bearing Race Installer), j8092 (Universal Driver Handle- 3/4 inch -10), j8608 (Rear Pinion Bearing Race Installer), j8611-01 (Rear Pinion Bearing Race Installer), j8614-01 (Flange and Pulley Holding Tool), j22912-01 (Split-Plate Bearing Puller), j24433 (Pinion Cone and Side Bearing Installer), j33782 (Pinion Oil Seal Installer), and j38694 (Extension Housing Oil Pump/Seal Installer). To start the process you must elevate the vehicle while taking out the drive pinion and Differential from the axle. The j22912-01 tool will extract the bearing from the pinion before removing the shim and both Pinion Bearing cups from the axle housing by applying gentle hammer blows with a brass drift. Install the outer Pinion Bearing cup via j7817 or j8611-01 combined with j8092 and the inner Pinion Bearing cup requires usage of j8608 and j8092. Install the determined selective shim in the correct position between the inner Pinion Bearing and the gear shoulder. First install the inner Pinion Bearing using j24433 which must sink onto the pinion shim, after which install a new collapsible spacer and apply mugelator to pinion bearings with proper axle lubricant. The axle housing receives the pinion after which you must install the outer Pinion Bearing followed by a new pinion oil seal with use of the j33782 or j38694. Sealant gm p/n 12346004 or canadian p/n 10953480 should be applied to the splines of the pinion yoke before installing it with a soft-faced hammer and relaying the marks from removal. Begin by placing the washer and new pinion nut in position and tighten them with the j8614-01 while adjust the yoke until pinion end play has just been reached. The pinion rotating torque should be between 1.0 - 2.8 nm (10 - 25 inch lbs.) for used bearings and 1.7 - 3.4 nm (15 - 30 inch lbs.) for new bearings when installing the pinion nut while following the proper torque measurement. The specified torque should be reached on the pinion before rotating it multiple times to verify bearing seating then torque should be checked and readjusted if necessary. The procedure concludes with axle lubricant installation followed by reinstalling brakes then tires and tires and finally lowering the vehicle.
