Suspension Crossmember

To change the front suspension crossmember, first, lift and prop the vehicle, then remove the front tire and wheel assemblies. Next, remove the Control Arm ball joint and stabilizer shaft link nut, lower and the tie rod end ball joint. Unbolt the mounts of the engine reaction rod and drain the power steering fluid before loosening off the fittings of the power steering pipe and the lower end of the intermediate shaft joint. It is very important to support the crossmember so that it does not drop when mounting bolts are removed. Following that, unfasten the crossmember assembly, and disconnect the stabilizer bar, power steering gear set, and Control Arm from the crossmember. For installation, start with the stabilizer bar, power steering gear set, and Control Arm installation onto the crossmember. Then, attach a crossmember to the assembly front pinned to the body nut and rear pinned to the body bolt and tighten them to 150 n.m (111 lb ft). Join the intermediate shaft lower joint and fittings of power steering pipe by ensuring that the fittings are tightened to 22 n.m (16 lb ft). Install the engine mounting reaction rod bolts with a torque of 60 n.m (44 lbs ft), then apply the nut for the tie rod end ball joint with 45 n.m (33 lb ft). In the last stages, you should install the Control Arm ball joint and stabilizer shaft link nut, lower and reattach the front tire and wheel assemblies, and lower the vehicle.

Support the crossmember to prevent it from dropping when the mounting bolts are removed.
