Drive/Propeller Shaft: Service and Repair
Rear Propeller Shaft Replacement
Rear Propeller Shaft Replacement (RPO LSA) (6.2L)
Caution: The propeller shaft must be supported during removal and/or installation so that the CV joint does not articulate more than 8 degrees.
Allowing the propeller shaft to articulate greater than 8 degrees could cause damage to the CV boot. Damage to boot could lead to contamination or loss
of lubrication which could lead to CV joint damage.
Removal Procedure
Note: Before removing the propeller shaft from the vehicle, paint or scribe references marks on the transfer case or transmission flange to the propeller
shaft and the rear differential drive flange to ensure minimal driveline system imbalance.

2. Remove the rear muffler. Refer to Exhaust System Replacement (With LY7 or LLT) (See: Engine, Cooling and Exhaust/Exhaust System/Service
and Repair).
