  Q: How do you remove and install the rear control arm and trailing arm?

  A: Loosen the lug nuts at the rear wheels and raise the back of the vehicle on jackstands, chock the front wheels. After that, remove the rear wheels, upper control arm-to-trailing arm mounting bolt and nut. Then remove fuel tank heat shield and fuel tank itself, follow with pivot bolt from inner end of arm. Inspect for deterioration control arm pivot bushing and replace it if necessary. For reinstalling fasteners in reverse order next to torque specifications are applied. In case of lower lateral control arm remove lower control arm-to-trailing arm mounting bolt and nut alongside with fuel tank heat shield and fuel tank. Following this take out pivot bolt from inner end of arm (note that rear stabilizer bar bushings may have to be removed for access). It is necessary to check on wear of control arm pivot bushing so as replace it wherever necessary. Replace the control arm in opposite sequence of removal procedure torquing specified fasteners properly. So as moving away trailing arms start by removing brake shoe or disc brake assembly, ABS wheel speed sensor and associated brackets first one thing to do is to remove a brake hose, brake line brackets parking-brake-cable and unbolt cable brackets as well as park them aside Remove hub & bearing assembly while holding out the brake backing plate then Slip a shock absorber/coil spring -to-trailing-arm mounting bolt together with a rear stabilizer bar link-to-trailing-arm bolt Unbolt the hub containing trailing arms using jacks; thereafter undo bolts securing upper & lower lateral controls arms Mark relationship between trailing arm mount bracket relative to car chassis before doing away with bracket bolts down towards fall No need to repeat checking for wear-edge since Pivot Bushings have been checked already When installing make match marks on mounting bracket that correspond those on unit chassis then secure it there by tightening the bolts Once you have done all these things we would then go ahead by tightening up all other fasteners to the prescribed torque values and then examine as well as adjust for any possible rear wheel alignment errors.

  Q: How to remove and replace a control arm on a Saturn LS and LS1?

  A: Loosen the wheel lug nuts on the side to be disassembled. Apply the parking brake, raise the front of the vehicle, support it securely on jackstands and remove the wheel. Remove the pinch bolt securing the balljoint to the control arm. Use a prybar to disconnect the control arm balljoint from the Steering Knuckle. To detach the control arm balljoint from the steering knuckle, remove the nut and bolt, then pry the balljoint out of the steering knuckle with a large prybar or screwdriver. Remove the bolts that attach the control arm to the subframe. Remove the control arm. Check the control arm for distortion and the bushings for wear, replacing parts as necessary. Do not attempt to straighten a bent control arm. If the bushings are cracked or show signs of wear, take the control arm to an automotive machine shop and have the bushings replaced. Installation is the reverse of removal, tighten all of the fasteners to the specific torque values. Before tightening the control arm pivot bolls, raise the outer end of the control arm with a floor jack to simulate normal ride height. Install the wheel and lug nuts, lower the vehicle and tighten the lug nuts to the specific torque. It's a good idea to have the front wheel alignment checked and, if necessary, adjusted after this job has been performed.
