Replacing the front suspension crossmember will involve first the installation of engine support fixture and lifting the vehicle. Turn the ignition switch off and slide the front tire and wheel assembly up and out of the car. Then remove the 3 nuts (12, 15, 16) from the crossmember, and hold the latter up with a jack. Remove the 2 nuts (4, 6) and the front suspension crossmember brace from the bracket studs (3, 7), as well as the bolt and 2 nuts from both the left and right control arms. Next, take out the 5 bolts (2,3,8,9,11) from the right side and the stud ' from the right and the ones from the left side; stud ' (2,3,5,6,7). Unbolt the 2 engines splash shields using bolts (5, 10) that clamp the 2 splash shields to the bans support, the 2 bolts (3, 4) that retain the front transaxle mount to the bans support, and the 2 bolts (1, 2) the secure bans support to the vehicle. Lower the jack to remove the front suspension cross member , bans support , 2 front control arms (8,9), and the front stabilizer shaft if applicable. If there is a front stabilizer shaft, remove the nut and the stabilizer shaft insulator clamp on the right side of crossmember remove the nut end Control Arm Bracket from the right side, removing the 2 nuts to loosen the stab stabilizer shaft links from the control arms. Take out the bolt and the front Control Arm from the right side, and then perform the same process on the left side, removing the nut and stabilizer shaft insulator clamp, the nut and Control Arm Bracket, and the bolt of the front Control Arm. Lastly, remove the bolt from the crossmember and the nut to sever off the bans support. For the installation, fix the bans support onto the front suspension crossmember using the nut and bolt, tightening it with 60 nm (45 ft. Lbs.). Mount the left front Control Arm with bolt and don't tighten, and then install the stabilizer shaft link if it applies and tighten the nut. Mount the left Control Arm Bracket with nut to 19 nm (14 ft. Lbs.) and the stabilizer shaft insulator clamp with nut 19 nm (14 ft. Lbs.). Repeat process for the right side making sure that everything is fixed, but not tighten until later. Mount the jack on the assembly to lift and support it, then fasten the 2 bolts, numbers 1 and 2 joining the ban's support to the vehicle without fastening and tighten the 2 bolts, numbers 3 and 4 for the front transaxle mount: tighten them to 64 nm (47 ft. Lbs.). Install the 2 engine splash shield bolts (5, 10) and tighten to 10 nm (89 inch lbs.), and install the (3, 7) studs and tighten to 147 nm (109 ft. Lbs). Bolt the 5 bolts (2, 3, 5, 6, 7) on the left side and the 5 bolts (2, 3 8, 9, 11) on the right side without tightening. Tighten the 2 nuts and bolt to secure the right front Control Arm, snugging them to 142 nm (105 ft. Lbs.) and repeating on the left front Control Arm. Undo the jack and carry out the 3 nuts (12, 15, 16) on the crossmember, tightening them to 57 nm (42 ft. Lbs.). Mount the front suspension crossmember brace and the 2 nuts (4, 6), tighten to 69 nm (51 ft. Lbs.). Replace the tire and wheel assembly, lower the car and bring it in contact with the tires. Lift the vehicle up and position it on a drive-on lift or alignment service rack, press the front bumper 3 times to ensure that the suspension is stable, and tighten the 2 vehicle support fasteners (1, 2) to the vehicle to 60 nm (45 ft. Lbs). Therefore, you are going to torque the inner bolt for the left Control Arm and bracket 175 nm (129 ft. Lbs) and front bolt for the left Control Arm 215 nm (158 ft. Lbs), and the front bolt for cross member 225 nm (167 ft. Lbs). Torque the bracket front bolt and outer bolt for the bracket as 225 nm (167 ft. Lbs.) and 147 nm (109 ft. Lbs.) respectively, an then the rear bolt to 123 nm (91 ft. Lbs.). Should this be possible, use a 5mm hex wrench to hold the left stabilizer shaft link stud while tightening the nut to 44 nm (33 ft. Lbs). Repeat process for the right side Control Arm and bracket, securing all bolts to their correctly allocated torque value. Last, lower the vehicle, take down the engine support fixture, and measure the wheel alignment adjusting if needed.
