Inspect the motor mounts and the transmission mount. Worn, weak or broken mounts will cause the torque arm to not function properly and can cause damage to your vehicle. Stock OE transmission mounts in Camaros and Firebirds are very weak and known to fail. If you have a broken or weak transmission mount, it will cause the torque arm to actually lift the tail end of the trans. up. This could cause severe wheel hop, driveline misalignment and possible damage to the transmission, drive shaft, u-joints, rear axle, torque arm, and/or floor pan of vehicle. We highly recommend using a good quality polyurethane transmission mount like Energy Suspension #33- 1108. Using the Energy Suspension transmission mount is good insurance that your transmission stay solid and the torque arm will work to its full potential. 2. Inspect the rear suspension bushings. We strongly recommend using either Edelbrock (#5274) lower trailing arms with a spherical ball on one end and polyurethane bushings on the other, Edelbrock (#5204) trailing arms with polyurethane bushings on both ends, or other high quality trailing arms that use high quality polyurethane bushings. We also recommend the use of an Edelbrock or other high quality panhard rod to replace the stock OE piece that uses sponge rubber bushings. The lower trailing arms and panhard rod secure the rear axle under the car. Upgrading to stronger high quality tubular trailing arms and panhard rod with polyurethane bushings will increase the overall strength, eliminate the sponge feel of rubber bushings and further increase the function potential of the torque arm. Worn out trailing arm or panhard rod bushings can contribute to or cause torque arm or other suspension component failures. Remember each suspension component

TOOLS REQUIRED 10 mm Socket Torque wrench Rubber mallet 2 Exhaust pipe finishers 3. While pushing the exhaust pipe finisher firmly against the exhaust pipe, tighten the flange bolt. Torque the flange bolt to 10 N·m (7lbs-ft.). Repeat for the second exhaust pipe finisher. 2. With the flange bolts facing down, slide the exhaust pipe finishers onto the exhaust pipes until they bottom. If necessary, use a rubber mallet to tap the exhaust pipe finishers into place. 4. Start the engine and rev it up a few times. Listen for vibration from the exhaust pipe finishers and adjust if necessary.

REPAIR PROCEDURE: 1. Raise the vehicle on an alignment rack (drive-on lift). 2. Verify the road tires are correctly sized and the tire tread is not excessively worn. Replace any worn tire before proceeding. Any new or old replacement tire should be equal to the original tires that came with the vehicle when it was new. Tire wear is not covered by the vehicle warranty. 3. Set the tire pressure for the FRONT TIRES to the following specification, regardless of the load being carried by the vehicle . Tire Size FRONT Tire Pressure LT235/80R17EorLT245/70R17E 448 Kpa (65 psi) LT265/70R17EorLT285/70R17E 414 Kpa (60 psi) 4. Set the tire pressure for the REAR TIRES as recommended for the vehicle configuration and load that is being carried at the time. Tire Size REAR Tire Pressure LT235/80R17EorLT245/70R17E Refer to the Tire Inflation Chart brochure in the Owners Manual or to the placards located either on the face of the driver’sdoor or on the driver’sside”B”pillar. LT265/70R17EorLT285/70R17E Refer to the Tire Inflation Chart brochure in the Owners Manual or to the placards located either on the face of the driver’sdoor or on the driver’sside”B”pillar. 5. Verify that the steering damper is operating correctly. a. Unbolt the end of the damper at the axle end. b. Cycle the damper rod by hand. c. There should be resistance to motion in both directions of the damper rod. d. Replace the damper if no resistance is present. 6. Verify both outer tie rod ends dustcovers are not worn. a. Attempt to rotate the dustcover by hand. b. If the dustcover on an outer tie rod end can be rotated, or is free and loose, then replace the tie rod (regardless of joint wear). 7. Inspect each outer tie rod end for internal wear. a. Maximum allowed wear (joint travel) fora tie rod end is 1.15 mm (0.045 in.). b. Install a dial indicator to the tie rod end (in-line with the vertical stud of the tie rod end). c. With a pry bar placed between the steering linkage and the axle tube, pry upwards while measuring the amount of joint travel (wear). d. Measure the amount of wear in the other outer tie rod end joint. e. If wear (joint travel) in either outer tie rod end is greater than 1.15 mm (0.045 in.), then replace the worn tie rod end. 8. Verify the torque on each outer tie rod end stud nut. The nut should be tightened to 122 Nm (90 ft. lbs.). 9. Make sure any worn outer tie rod ends have been replaced before proceeding further. 10. Verify all other steering linkage connections are tightened to their torque specifications.
