Service and repair of the front control arm should begin by positioning the vehicle in neutral mode on a hoist. A service or repair of the upper arm requires you to begin by extracting the
Shock Absorber and spring assembly from the arm. The removal procedure follows the illustrations and tables while keeping the hex holding feature on to stop stud movement as you take away the nut from ball joints and stabilizer bar links. The caliper must not be suspended from the hose while removing pads and anchor plate and
Brake Caliper because it could lead to damage. The first step for upper arm-to-body nut removal involves discarding the nut and moving the
Power Steering Reservoir aside while you disconnect both the fluid level sensor connector and the
Brake Master Cylinder main pressure transducer electrical connector if your vehicle is equipped with these components. The reservoir bolt needs backing out so the master cylinder bolt becomes accessible before removing the two master cylinder brake nuts to set the master cylinder off to the side. The procedure to remove lower arm-to-frame bolts includes three steps: first eliminating screws and pushpins along with destroying the protective shield, then unwinding the nuts and bolts followed by moving the steering gear outside the working area before loosening the lower arm bolt. The front end needs examination for alignment before ending the installation of the lower arm. Installation should finish before tightening either lower arm-to-frame nuts or upper arm-to-body nuts when the vehicle stands on its wheel and tire assemblies alone. A thin layer of lubricant should be applied to the bearing surface which joins with the knuckle for the wheel bearing installation.
