Service the driveshaft by applying these procedures when your vehicle is in NEUTRAL position on a hoist. Start by taking off the flex pipe exhaust and then remove the exhaust support brace bolts followed by the brace before fastening brake bolts to 30 Nm (22 ft. lbs.) torque. The driveshaft requires proper indexing which should be performed to the rear axle pinion flange and to both the power take off (PTO) flange and center bearing bracket to avoid noise vibration or harshness issues. New driveshaft flange bolts should always be utilized for removal; afterward discard original bolts and tighten new flange bolts to 25 Nm (18 ft. lbs.) through a cross pattern method. You should eliminate the center bearing bracket bolts and driveshaft however tighten fresh bolts to 25 Nm (18 ft. lbs.) for the reinstallation step. During new driveshaft installation remove the center bearing bolts alongside the bracket and tighten the new bolts to 20 Nm using a cross pattern. To install the driveshaft conclude by hand-tightening bolts to PTO flange and rear axle pinion flange until security of the center bearing bracket bolts is maintained. The attainment of correct bolt torques at specified values completes the installation process.

Start by removing the muffler and tailpipe before detaching the exhaust support brace by removing its bolts followed by reinstallation and tightening the bolts to 30 Nm (22 ft. lbs.). The driveshaft needs index marking at three key points for rear axle pinion flange and power take-off (PTO) flange together with center bearing bracket to stop Noise Vibration and Harshness issues. Install fresh driveshaft flange bolts for every removal procedure since old bolts must be discarded when disconnecting from the rear axle pinion flange and the PTO flange; tighten new bolts to 25 Nm (18 ft. lbs.) through crosswise bolt patterns. Proceed to take out the driveshaft by removing the center bearing bracket bolts and replace it while tightening these bolts to 30 Nm (22 ft. lbs.). Installation of a fresh driveshaft requires disconnecting center bearing bolts while also taking out the center bearing bracket to be followed by new bolt installation and post-installation tightness set at 20 Nm (15 ft. lbs.). Finish up the installation by initially manually tightening the driveshaft flange bolts to PTO flange and rear axle pinion flange before tightening the center bearing bracket bolts and unwinding the driveshaft according to the previous uninstall steps.
