Q: How to replace a one-piece Drive Shaft on Chevrolet Colorado?
A: The replacement procedure for one-piece propeller shaft begins by setting the transmission to neutral then removing either the park brake if present. The repair process requires vehicle elevation followed by marking of the Drive Shaft flange and rear Universal Joint relationship. You must first remove all retaining bolts along with clamps which enables the removal of the propeller shaft from the pinion drive flange and the transmission/transfer case. The u-joint bearing caps must remain together so tape or a rubber band should be applied around them. The u-joint requires removal of tape or rubber band before the propeller shaft can be installed into the transmission/transfer case while maintaining alignment with pinion flange reference marks. Place the clamps with bolts before lowering the vehicle and secure them at 20 n.m (15 lb ft).
Q: How to replace the Drive Shaft on Chevrolet Equinox?
A: Begin the propeller shaft replacement process by installing a support under the rear drive module then keeping the transmission at neutral position. Position vehicle supports under the propeller shaft while marking the positioning between shaft and rear drive module flange. The propeller shaft yoke flange needs its bolts removed from the rear drive module flange before indexing the propeller shaft in relation to the power take-off unit (PTU) flange. First position the propeller shaft for support at the ptu before fixing all bolts holding the ptu flange. The support bearing requires proper support after which you must remove bolts between the support bearing and vehicle underbody. The propeller shaft becomes ready to remove once the mechanic supports it while pulling it toward the rear to free the constant velocity joint from the ptu flange. When reinstalling the propeller shaft into the vehicle always maintain sustained support at its front section as well as its center and rear sections. After cleaning the vehicle-mounting bolts of the center bearing technicians must apply thread locker (Canadian P/N 10953488) to these bolts before their installation. Supporting the propeller shaft during this procedure remains essential. Install the propeller shaft forward section onto the ptu flange by pulling it backward until the index marks between the constant velocity joint and flange align. Apply thread locker canadian p/n 10953488 to the propeller shaft flange bolts and clean them before mounting bolts to the front of the shaft using 50 n.m (37 lb ft) torque. Place the index marks of the propeller shaft yoke flange and rear drive module flange in alignment and apply propeller shaft yoke and rear drive module flange bolts before tightening them to 50 n.m (37 lb ft). Lower the vehicle after removing support stands from the propeller shaft then tighten support bearing mounting bolts to 25 n.m (19 lb-ft).
Q: How to replace the rear Drive Shaft on Chevrolet Tahoe?
A: The first step for propeller shaft replacement includes precise component tagging of the driveline system before disassembly so all parts can return to their original positions during reassembly by following torque specifications. Begin by raising the vehicle. Note down the positioning of the propeller shaft regarding the rear axle pinion yoke and the transmission or Transfer Case. The yoke retainers must be removed then bolts need to be separated from the rear axle pinion yoke. When removing the yoke ears it is essential to avoid using tools between the yoke and Universal Joint because it can lead to injection joints fracture. The process for removing the propeller shaft begins with moving it forward to detach from the rear axle pinion yoke and continues with retraction back toward the transmission or Transfer Case before completing the removal of the shaft from the vehicle. The Slip Yoke splines need inspection for lubrication before installation, use gm p/n 12345879 (Canadian P/N 10953511) or equivalent gm specification 9985830 (RWD w/4-speed Automatic Transmission) as lubricant when required. Reinstall the propeller shaft into the transmission or Transfer Case by matching the reference marks from removal before inserting it to the rear axle pinion yoke where reference marks must be exactly aligned. Drop the vehicle and properly install the yoke retainers while using 25 nm (18 lb ft) torque on the retainers bolts.
