  Q: How Is a Rack and Pinion Power Steering Gear Installed on Chrysler 300M?

  A:

  During installation, ensure that the tie rod is found right in the center of the rack and pinion movement. To start, set up the steering hardware by removing it in the order you took everything apart and set the left front tire to be straight forward if your car has the 2.7 Liter engine. After that, put in the inner tie rod through the attached inner fender hole and secure the outer tie rod to the steering arm of the right strut, tightening the nut to 37 Nm (27 ft. lbs.). Properly install your tires and wheels and screw the mounting nuts in the correct order to half torque, after that tighten them to a full torque of 135 Nm (100 ft. lbs.). Raise up the vehicle so that the front tires are just off the ground, then place the intermediate steering shaft on the rack and pinion. Use Roll Pin Installer, Special Tool 6831A, to put the roll pin in the flex joint of the intermediate shaft, but stop when it is properly centered. Slip the rack and pinion and intermediate shaft into their boot so they hang accordingly, matching their holes to the crossmember below. Attach the left side mounting bolts loosely at first, then install the right side bracket bolts to 58 Nm (43 ft. lbs.) and finally, tighten the left side bolts to the same torque. If the bolts for the right side mounting bracket have been loosened prior to, hand-tighten them and then tighten them to 37 Nm (27 ft. lbs.). Be sure the spacer kit inside the bellows is properly aligned before fastening the lines securely using 47 Nm (35 ft. lbs.). If you've chosen speed proportional steering, attach the wiring harness to the solenoid control valve. Adjust the centered take-off connection from the rack and pinion to each tie rod assembly, install the tie rod attaching bolts and their washers and tighten to 100 Nm (74 ft. lbs.). Join the intake manifold vacuum port to the power brake booster's vacuum hose using a hose clamp and tighten the nuts on the master cylinder to 28 Nm (250 inch lbs.) after installing it on the power brake. Put the wire in place with the brake fluid level switch on the master cylinder reservoir and add the in-line resonator and hose to the throttle body as well as the air inlet hose from the lid on the air cleaner housing. Add the cowl reinforcement to the vehicle by mounting it with eight bolts onto the strut towers and one to the wiper module. Cover the wiper module and cowl with their respective covers, fix the screws and connect the Wiper Arms to the pivots using nuts and their caps. Insert the intermediate shaft into the steering column shaft and tighten the coupler pinch bolt to 28 Nm (21 ft. lbs.). Then put the retaining pin in place. Take out the holding clamp, attach the battery ground cable to the shock ground stud, repeat the PS pump start up procedure, lower the vehicle and change the front toe.

  Q: How to Remove a Rack and Pinion Steering Gear on Chrysler 300M?

  A:

  To disconnect the power steering rack and pinion, start by disconnecting the ground side of the Battery Cable from its ground stud on the shock tower and put a cable isolator on it. Place the front tires in a straight line, then fit a holding clamp on the Steering Wheel to lock it from rotating. First, remove both the retaining pin and the coupler bolt, then part the intermediate steering shaft from the coupler. Use a frame contact hoist to raise the vehicle until the front tires are no longer touching the floor. After removing the caps, reach the nuts under the Wiper Arm by loosening the wiper arms back and forth. Take the cowl module and reinforcement off by undoing eight bolts for the reinforcement and the single bolt that held the wiper module in place. Eliminate the in-line resonator and the inlet hose from the Throttle Body and the air let hose from the air cleaner housing. If the steering rack and pinion automatically reacts to speed, disconnect the solenoid control valve from the harness located on the rack and pinion end cap. Loosen the two nuts keeping the master cylinder connected to the vacuum, take off the brake fluid level switch connector and pull the entire cylinder and brake tubes to the upright position on the left side valve cover to keep the fluid from spilling. Remove the foam washer and disconnect the hose from the power brake vacuum booster. At the same time, bend the tabs on the tie rod to rack and pinion mounting plate. Lift out the bolts, the mounting plate and the washers under the tie rods at the rack and pinion and lay them on top of the transaxle bell housing. Remove the fluid using a siphon pump and take out the fluid pressure and return hoses from the rack and pinion after that. Unbolt both bolts holding the left side rack and pinion to the crossmember and the two bolts holding the right side bracket, as well as possibly uncross the right mounting bolts to free the air conditioning lines. Push the rack and pinion and intermediate shaft forward so you can reach the intermediate shaft flex coupler retaining pin in the rack and pinion shaft. Then, extract that roll pin using Special Tool 6831A. Disconnect the steering shaft from the rack and pinion, lift the car and remove the wheel on the right front side. Unlock the nut that holds the tie rod end to the steering arm on the right strut and use Puller, Special Tool C-3894-A, to free the tie rod end from the steering arm. Drop the tie rod from the car, making sure the left front tire/wheel is turned out before removing it if your car has a 2.7 liter engine. After that, guide the rack and pinion into the tie rod hole on the inner right fender until half is out, raise the left portion of the rack and pinion away from the car and guide it to the passenger side to take it out from between the engine and the cowl.
