The engine support insulator removal and replacement process should start with vehicle hoisting at neutral while disconnecting the battery ground cable. The next steps in this procedure require removal of the
Throttle Body (TB) together with the cooling fan and generator and
Starter. 4WD vehicles need the front
Drive Shafts to be detached from the vehicle. You should install the engine support bar with the support hook before using the engine support bracket to remove 4 Y-pipe flange nuts. Use hand tools only to loosen the two transmission mount-to-crossmember nuts since power tools might cause damage. The mechanic must first loosen the LH engine support insulator through bolt along with removing the RH engine support insulator through bolt. They should follow up by taking out the 2 RH engine support insulator nuts and the 2 RH engine support insulator stud bolts through only hand tool applications. Begin by positioning a hydraulic jack below the front axle before securing it with support and then proceed to remove upper front axle carrier mounting bushing bolt,
Axle Shaft housing carrier bushing bolt, and lower front axle carrier mounting bushing bolt. The axle must be lowered to expose the RH lower front mount bracket bolt before the engine elevation using engine support bar and support hook along with engine support bracket allows removal of three bolts securing the RH engine support insulator-to-cylinder block bracket for the removal of the RH engine support insulator. To access the LH engine support insulator begin by unbolt the RH engine support insulator through bolt while raising the engine so you can remove the 3 engine support insulator-to-frame bolts which you should discard. Uninstall the LH engine support insulator-to-cylinder block bracket by removing its 3 securing bolts and then remove the LH engine support insulator. Thread damage should be replaced with service part number 56190 when found on the engine support insulator-to-frame nut plate. The mating surfaces of the RH engine support insulator require cleaning before installing it with two 15 Nm (133 lb-in) tightened stud bolts. Position the RH engine support insulator-to-cylinder block bracket and tighten its three bolts to 63 Nm (46 lb-ft) then install the two engine support insulator nuts to 175 Nm (129 lb-ft). Apply cleaning to mate the LH engine support insulator surfaces then position it for hand starting the new 3 engine support insulator-to-frame bolts which should be tightened to 175 Nm (129 lb-ft). The position of the LH engine support insulator-to-cylinder block bracket requires three bolts which should be tightened to 63 Nm (46 lb-ft). The engine support insulator bolt installation requires engineer threadlock and 350 Nm (258 lb-ft) torque for both the left-hand and right-hand sides. The front axle carrier needs to be raised before installation of three bolts including lower front axle carrier mounting bushing bolt, axle shaft housing carrier bushing bolt and upper front axle carrier mounting bushing bolt which must be torque to 115 Nm (85 lb-ft) for 4WD vehicles. Complete the installation by fastening transmission mount-to-crossmember nuts to 103 Nm (76 lb-ft) and placing the Y-pipe followed by mounting the 4 nuts (2 right and 2 left) to 40 Nm (30 lb-ft), and finally extract the engine support bar, support hook and engine support bracket. Put back the starter with the generator and cooling fan and TB in addition to the battery ground cable and front driveshaft (if needed).
