2009 Chevrolet Tahoe Rack and Pinion Seal

You need to use the J 37624 and the J 8092 to install the inner pinion bearing cup into the pinion gear bearing retainer, use the J 8608 and the J 8092 to install the outer pinion bearing cup into the pinion gear bearing retainer, apply a sealant to the surface of the selective shim, install the pinion gear bearing retainer and bolts, the drive pinion flange/yoke and/or oil seal, the rear propeller shaft from the vehicle and the rear axle shafts, fill the axle with axle lubricant and remove the support and lower the vehicle.

You need to use the J 44414-installer to install a new pinion oil seal, apply a sealant to the splines of the pinion yoke, install the drive flange onto the pinion shaft, use and hold the J 8614-01-holder/remover to tighten the pinion nut until the pinion end play is just taken up, rotate the pinion while tightening the nut to seat the bearing and use an inch-pound torque wrench to tighten the nut in small increments. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated. Then you can install the propeller shaft assembly, the axle shafts, the rear brake rotors, and the tire and wheel assemblies, inspect and add axle lubricant to the axle housing and remove the support and lower the vehicle.

You need to drain the axle lubricant, remove the rear axle shafts, the rear propeller shaft from the vehicle, and the drive pinion flange/yoke and/or oil seal, use a hydraulic press and an appropriate tool to remove the pinion, remove the collapsible spacer, use a hammer and a brass drift in the slots provided to remove the outer pinion bearing cup and use a hammer and a brass drift in the slots provided to remove the inner pinion bearing cup.

You need to remove the tire and wheel assemblies, the rear wheel axle shafts, the rear brake rotors, and the propeller shaft from the vehicle use an inch-pound torque wrench to measure the amount of torque required to rotate the pinion, place an alignment mark between the pinion and the pinion yoke, use the J 8614-01-holder/remover and holding it to remove the pinion nut, remove the washer, use the J 8614-2 and the J 8614-3 to remove the pinion yoke and use a suitable tool to remove the drive pinion seal.

The recommended torque is 88 Nm(65 lb-ft).
