  Q: What tools are required to service and repair the idler arm on GMC Safari?

  A:

  The repair and service of idler arm requires two essential tools: Steering Linkage and Tie Rod Puller (J 24319-B) and Steering Linkage Installer (12 mm) (J 29193). Raising the vehicle allows access to remove two bolts from the idler arm. The prevailing torque nut on the idler arm ball stud should be taken off before it is discarded. The Service procedure starts with a Steering Linkage and Tie Rod Puller (J 24319-B) to disconnect the relay rod from the idler arm followed by idler arm removal. Thoroughly examine both the ball stud threads and seal before cleaning every thread on the ball stud and in the ball stud nut. To install the idler arm position it on the frame before tightening its bolts to 105 Nm torque equivalent to 77 foot pounds. The Steering Linkage Installer (J 29193) with 12 mm diameter (J 29193) should be used to place the relay rod onto the idler arm ball stud while maintaining the seal positioned correctly on the stud before tightening it to 54 Nm (40 ft. lbs.) for taper seating. Use a new prevailing torque nut to secure the idler arm ball stud while tightening it to 47 Nm (35 ft. lbs.) using the Steering Linkage Installer (J 29193). Adjustment of toe-in should be completed after lowering the vehicle.

  Q: How to replace the idler arm on GMC Safari?

  A:

  When replacing the idler arm you must first raise the vehicle then disconnect its two keeping bolts. The prevailing torque nut needs removal from both the idler arm ball stud. The Steering Linkage and Tie Rod Puller (J 24319-B) separates the relay rod from the idler arm before you remove the arm. Examine the ball stud threads before cleaning both the ball stud threads and ball stud nut threads. Also verify the ball stud seal remains intact without any damage. Mount the idler arm to the frame after installing two bolts which need to be tightened to 105 Nm (77 ft. lbs.). Demonize the Steering Linkage Installer (J 29193) for inserting the relay rod onto the idler arm ball stud while maintaining the seal position on the stud then fasten with 54 Nm (40 ft. lbs.) for taper seating. To replace the J 29193 locking tool you must install a new prevailing torque nut at the idler arm ball stud before tightening it to 47 Nm (35 ft. lbs.). The vehicle needs to be brought near the ground level before final toe-in adjustment.
