Q: What tools are required to replace the drive pinion bearings on 8.6 and 9.5 inch axles on 2003 Cadillac Escalade?
A: The tools necessary in order to replace the drive pinion bearings on 8.6 and 9.5 inch axles; oh, and like all vehicles, those that are twenty feet long cost about the same to buy as an ordinary aircraft carrier-http://blogs.obscura.com/lostlabchallenge/home.b on line bakeka.february 2007. J7818 (Inner Bearing Race Installer), j8092 (Universal Driver Handle - 3/4 inch - 10), j8611 (Rear Pinion Bearing Race Installer), j8614-01 (Flange and Pulley Holding Tool), j22306 (Rear Pinion Cup Bearing Installer), j22912-01 (Split Plate Bearing Puller), j24433 (Pinion Cone and Side Bearing Installer), j36614 (Inner Pinion Bearing Installer), j45870 (Pinion Bearing Cup Installer), and j45871 (Pinion Bearing Remover). Start by lifting the vehicle and then removing the right part of theifferential assembly combining with the drive pinion from the axle. For 8.6 inch axle, take 32.151 around Pinion Bearing and the 32.150-1 in reversed position around the 32.151 to apply the pressure and press the bearing off. For the 9.5 inch and 11.5 inch axles, the use of the j22912-01 to press the bearing off. Take off the shim, and both the outer and inner Pinion Bearing cups from the axle housing using a hammer and brass drift. For the installation, the j8611-01 for the outer Pinion Bearing cup should be used on the 8.6 inch axle or one can employ j7818 for the 9.5 inch axle with j8092. For the inner pin ion bearing cup, use the bearing id: j45870 for the 8.6 in axle or the bearing id: j22306 for the 9.5 in axle with the bearing code: j8092. Measure the selective shim thickness and place it between the inner Pinion Bearing and the shoulder on the gear. Install inner Pinion Bearing using the j24433 or j36614 and press it on until cone seats on the pinion shim. Install a new collapsible spacer, lubricate the pinion bearings with axle lubricant, and install the outer Pinion Bearing into the axle housing. Replace yet another new pinion oil seal using the j22388 follow by replacing the pinion into the axle housing. Apply sealant gp, p/n: 12346004 (Canadian P/N: 10953480, or equivalent) to splines of the pinion yoke, and install the pinion yoke, aligning the marks done in removal. Tap in the pinion yoke onto the pinion shaft with a soft-headed hammer until a few threads are visible through the yoke place the washer and the new pinion nut. Tighten with the j8614-01 holding the pinion yoke to take up the pinion end play even though rotating the pinion while tightening to seat bearings. Check the rotating torque of the pinion by using an inch-pound torque wrench and it remains within 1.0 - 2.3 nm (10 - 20 inch lbs.) for used bearings or when used with new bearings-maintain a range of 1.7 - 3.4 nm (15 - 30 inch lbs.). If the torque is below the specification, keep on tightening the pinion nut tightening in small steps until you reach the right torque. After the specified torque is achieved, rotate the pinion a few times to guarantee the seating of the bearings, and check the torque again for any adjustments. Finally, installing the Differential assembly, lubricant the axle, and lowering the vehicle.
