  Q: How to service and repair the upper control arm bushing on Mercury Mountaineer?

  A: First service the upper arm bushing while keeping in mind that suspension fasteners serve as critical system performance elements that often produce major service expenses when they fail. The installation of new fasteners requires using original component numbers or their equivalent while excluding inferior quality and alternate designs. Proper retention of fasteners needs the maintenance of torque values during assembly while preserving their original installation orientation. The procedure for upper arm-to-frame mounting bolt removal requires these hardware components to pass through the frame and bushing before completing bolt tightening. All fasteners should remain loose until the installation is finalized when the vehicle weight rests on wheel and tire assemblies. The two upper arm-to-frame bolts should be taken off from their rearward positions while the two upper arm-to-frame flag nuts should be removed afterward. Before installation you should tighten an upper arm bushing-to-upper arm nut with a value of 120 Nm (89 ft. lbs.). To replace the upper arm bushing (rearward mounting) follow the reversal of removal steps with proper tightening of upper arm-to-frame bolts to 80 Nm (59 ft. lbs.).
