2009 Chevrolet Trailblazer Driveshaft

First, you need to remove the tire and wheel assembly, the brake caliper, the rear wheel speed sensor, the rear axle housing cover and the gasket, and the pinion shaft locking bolt. Then, please remove the pinion shaft (on axles without a locking differential), or remove the shaft partway (on axles with a locking differential), enter the differential case, and rotate the C-lock until the C-lock aligns with the thrust block. Finally, you should push the flange of the Axle Shaft toward the differential, remove the C-lock from the button end of the axle shaft, and remove the axle shaft from the housing. If the axle is difficult to remove, you should use the J 45859 and the J 2619-01 to remove the axle shaft from the housing.

First, you need to place the half-shaft in a vise, place protective covers over the vise jaws, use a hand grinder to cut through the swage rings, compress the seal on the half-shaft and away from the constant velocity (CV) joint outer race and wipe all grease away from the face of the CV Joint. Then, please find the half-shaft retaining snap ring, which is located in the inner race, spread the snap ring ears apart, pull the CV joint from the half-shaft, discard the old seal, place a brass drift against the cage, tap gently on the brass drift to tilt the cage, remove the first ball when the cage tilts. You need to repeat the previous step to remove all of the balls. Finally, you should pivot the cage and the inner race 90 degrees to the centerline of the outer race and align the cage windows with the lands of the outer race, lift out the cage and the inner race, remove the inner race from the cage by rotating the inner race upward, degrease all of the CV joint parts, check the outer CV joint assembly for unusual wear, cracks, or other damage, and clean the half-shaft bar.

Lubricant leaks at the Differential carrier assembly can occur at the Drain Plug, the Fill Plug, or the Vent tube.
