Only remove six lower transmission crossmember bolts at this point but reinstall them tightly using 80 Nm (59 lb-ft) torque when installing back. Tighten the nuts located on the joint's nut side first while removing the two nuts along with two bolts from the transmission crossmember. Reinstall these components with a torque of 103 Nm (76 lb-ft). Complete the operation by uninstalling the transmission crossmember then perform step-by-step reverse installation.
