Question 1

How Does Proper Installation of a Crossmember Bushing Affect Ride Quality and Longevity on Dodge Challenger?

Accepted Answer

See which side the trip limiter is pointing so you ensure you install the correct rear cross-member bushing type. Bushings are applied in the same way they were installed originally, matching the marks applied during removal to support the vehicle's longevity and comfortable ride. Open the can and get the bushing in place on the crossmember, making sure the can flange lines up with the markings. Be sure to use the Receiver 9031-6, Press C-4212F and the Installer 9031-7A while installing, placing the Installer carefully to handle the compression link bracket. Tighten the screw in Press until the can flange touches the surface of the crossmember. With the tools taken out, see that the bushing is correctly located and put the bolt and nut in place on the crossmember without fully tightening them. Place the crossmember on top of the body where the mounting points are, fit the propeller shaft onto the rear differential and slide the shock absorbers into place in the spring links. Due to their length, the rear mounting bolts cannot be put in the front without damaging the bike. Raise the crossmember just enough to access the mounting bolts, set the bolts on the left and do not tighten the ones on the right. Slowly lower the jack to permit the right side of the crossmember to move down slightly, so the coil spring can be fitted and isolators can be positioned on its ends. Put the coil spring with its isolators into the spring pocket and line up the top of the spring with the body mount. Carefully lift the jack so the coil spring and shock absorber are in position, attach the lower shock mounting bolt and nut and then don't tighten the nuts yet. For cars with AWD, fit spacers onto the right crossmember mount bushings, only after which you can lift the crossmember. Lift the right crossmember up to its position and install the right mounting bolts; leave these in place but don't tighten fully yet. After removing both crossmember mounting bolts from the left side, steady the jack so that the crossmember on the left drops; the coil spring and isolators should be installed while the crossmember is down. While raising the jack, fit the coil spring and isolators so the spring and absorber line up with the body mount. Afterwards, install the lower bolt of the shock and do not tighten it. Before raising the left crossmember on an AWD model, first insert spacers into the mount bushings across the top. Put the left side of the crossmember into place and install the bolts in the left side with one on each side, but do not tighten them yet. Position the crossmember as required to make the mounts line up with the location points on the car and check that the gap between the tension link and weld flange is at least 12 mm for correct suspension movement. Screw all four crossmember mounting bolts to 180 Nm (133 ft. lbs.), get rid of the jack supporting the differential and free the propeller shaft from the bungee cord. Make sure the propeller shaft index marks match and then tighten the rear coupler-to-axle flange bolts to 81 Nm (60 ft. lbs.). Attach the fuel filler pipe, clip the rear wheel speed sensor for the left side to the routing bracket and connect the left sensor to the right one. Insert the speed sensor connectors into the body wiring harness connector, verifying that the retaining clip is in its place. When working with disc brakes, first insert caliper guide pins into the caliper adapter, lead the caliper through the back suspension and attach it over the pads on the adapter, without mistakenly twisting the caliper guide pin bolts as you do so. Fasten the guide pin bolts to 31 Nm (23 ft. lbs.) and be sure the brake hose is not twisted or damaged. For the SRT8's disc brake system, lift the spring link and bring all four caliper pads to the brake rotor, secure the caliper in place with its bolts, then tighten these to 130 Nm (96 ft. lbs.). Cable the parking brake from the back crossmember, so the front parking brake cable links to the right rear parking brake cable at the connector. Fit the parking brake cable guide bracket at the front and screw it to the car's rear crossmember. Applying 150 Nm (110 ft. lbs.) of pressure to the mounting nuts, put on the rear exhaust system and tire and wheel assemblies. Bring the car down so the back wheels are off the ground, pull the parking brake and let it go again and check that the rear wheels don't spin when the lever is engaged. Set the vehicle onto the ground, link the cable for the battery's negative terminal to the battery and push the brake pedal many times to verify a firm pedal. Have the vehicle strapped to an alignment rack, raise it if required and tighten the shock absorber lower mounting bolt nuts to 72 Nm (53 ft. lbs.) and the compression link bolt nut and bolt at the crossmember to 85 Nm (63 ft. lbs.). During a wheel alignment, put emphasis on the thrust angle and if it needs to be adjusted by shifting the rear crossmember, make sure space in the tension links is still available.

Question 2

How to Service and Repair a Rear Crossmember Bushing on Dodge Charger?

Accepted Answer

First, detach and isolate the negative side of the battery cable from the post and then raise and hold up the vehicle before servicing the rear crossmember bushing. Take off the wheel mounting nuts and tire and wheel assembly, as well as the entire rear exhaust, on each side of the car. Draw alignment index marks on the rubber coupler and where the flange joins, then remove the bolts and nuts holding the propeller shaft rubber coupler to the axle flange, with the propeller shaft being supported by a bungee cord. First, cut the front parking brake cable from the connector, then take out the cable from the equalizer and lastly unscrew the routing bracket holding at the rear crossmember's front flange. To work on a car with standard or premium disc brakes, unbolt the guide pin of the disc brake caliper, separate the caliper and pads and support the caliper from the rear of the car above the suspension. Slice each disc brake pad using a piece of sandpaper, dump the pad filler out of the ABS reservoir and lay out the disc pads. Separate the wheel speed sensors from the body wiring, remove the left wheel speed sensor cable by unclipping it and take out the lower bolt and nut on either side of the vehicle that hold the shock absorbers. Put marks at all four places where the rear crossmember will be fastened, secure the cradle's forward end with jack stands and attach a jack to the rear under the axle differential. After disconnecting the fuel tube and removing all bolts, slowly lower the crossmember so the propeller shaft comes out. Lift the actual spring down to a reasonable height, remove its isolator and mark where the bushing is. Slide Support 9031-11 all the way into the crossmember at the opening for the bushing, secure it with the set-screws, put Brace 9031-12 between this Support and the bushing bore flange and again tighten the set-screws without overdoing it. Place Press C-4212F, Remover 9031-2 and Receiver 9031-1 around the bushing, tighten the Press screw-drive and remove all instruments. When installing, place the new bushing on the crossmember so it aligns with the indicated lines, add Press C-4212F, Receiver 9031-3 and Installer 9031-4 on top of the bushing and tighten the Press screw-drive to press the bushing in until the flange meets the crossmember. Place each crossmember hinge over the body mounting points on each side and line up the propeller shaft with the diff of the rear axle. Install the isolated crossmember mounting bolts just enough so the crossmember doesn't move and then place the car on the jack to enable future spring placement. Attach the coil spring and low end of the shock absorber and then put in the unable shock mounting bolt and nut without tightening. Before lifting the right crossmember, put spacers on top of the right crossmember mount bushings and then secure the mounting bolts from the top of the vehicle. Release the bolts from the left side cross member, lower the jack so you can mount the coil spring and do the same on the right side. Move the crossmember so the mounts are right where the location marks were, measure the distance between the tension link and weld flange to make sure it is no less than 12 mm and make changes as needed. Tighten each crossmember bolt until the torque gauge reads 180 N.m (133 ft.lbs.), take out the jack from under the rear axle differential and loosen the bungee cord around the propeller shaft. Place the propeller index marks together, place the rear coupler-to-axle flange bolts, then tighten them to 81 N.m (60 ft.lbs.). Put the fuel filler tube into place, attach the left rear wheel speed sensor cable and plug in the speed sensor connectors to the large wiring harness. For standard or premium disc brakes, pull the caliper and its hose down to the bottom of the rear suspension, place the caliper over the brake pads and secure the guide pin bolts, tightening them to 31 N.m (23 ft.lbs.). SRT8 disc brake support should be placed on the spring link. Then slide the caliper over the rotor, install the mounting bolts and tighten those to 130 N.m (96 ft.lbs.). Connect the parking brake cable in the wheel well, join the front parking brake cable and put in the routing bracket screw. Put back the rear exhaust, the tire and wheel and make sure the wheel nuts are tightened to 150 N.m (110 ft.lbs.). Set the car lower, apply the parking brake, release the lever and see if the movement is stopped at the wheels. After connecting the negative cable, pump the brake a few times, place the car on an alignment rack and tighten the lower shock mounting bolt nuts to 72 N.m (53 ft.lbs.).
