Lower Control Arm, Driver Side

Start by supporting the vehicle's elevation and then install a safety stand beneath the lower Control Arm for support. Start by taking off the wheel and tire then remove the stabilizer shaft links from the lower Control Arm. First detach the shock absorber lower nut and bolt then remove the torsion bars before removing the wheel drive shaft. Use tools j 43631 Ball Joint separator with j 45851 Ball Joint separator protector adapters to disconnect the lower Ball Joint stud from the Steering Knuckle after removing the lower Ball Joint retaining nut. The work sequence starts with pulling off lower Control Arm nuts paired with 15-series washers followed by lower Control Arm bolts and then moving on to lower Control Arm nuts using 25/35-series washers and finally removing lower Control Arm bolts to extract the whole lower Control Arm. The installation requires positioning the new lower Control Arm followed by 15-series bolt installation and subsequent 25/35-series bolt installation while applying torque to 175 nm (129 ft. Lbs.). After putting the lower Ball Joint stud into the Steering Knuckle assembly you must install the corresponding nut followed by proper torque adjustment to 100 nm (74 ft. Lbs.). You should now install all components in the following order: the torsion bars first, then install the shock absorber lower nut and bolt, and finish by attaching stabilizer shaft links to the lower Control Arm. Reinstall the tire assemblies under the wheel followed by stand removal before vehicle lowering for alignment procedures.

The replacement of a lower Control Arm begins by raising the vehicle then installing support before wheel removal alongside tire detachment. Separate the stabilizer shaft link from the lower Control Arm then take off the wheel drive shaft if your vehicle has it. The knuckle assembly and upper Control Arm need support from mechanics wire or equivalent material. Begin by removing two components from the lower Control Arm: the lower Ball Joint retaining nut followed by the lower shock module bolts. Patented tools j 43631 (Ball Joint Separator) and j 45851 (Ball Joint Separator Protector Adapters) will help workers separate the lower Ball Joint from the Steering Knuckle. Release the lower Control Arm nuts then washers before removing the Control Arm bolts to extract the Control Arm. Place the new lower Control Arm into its proper position then fasten it down using Control Arm bolts and washers before tightening all retaining nuts to 175 n.m (129 lb ft). Set the lower Ball Joint into position within the Steering Knuckle then torque the retaining nut to a torque setting of 110 n.m (81 lb ft). Before removal of the Steering Knuckle support reattach the lower shock absorber module mount bolts at 50 n.m (37 lb ft) torque. The wheel drive shaft replacement and stabilizer shaft link installation must follow the lower Control Arm sequence. Complete the installation by reattaching the tire followed by wheel installation then removing the support before lowering the vehicle to perform front-end alignment.

Vehicle repair starts with vehicle lifting followed by wheel and tire removal. Start by removing the stabilizer shaft links from the lower Control Arm and after that remove the shock absorber lower bolt and nut. First disconnect the wheel drive shaft and torsion bars from the system then remove the lower ball joint stud nut. You can use ball joint remover j43631 to separate the lower ball joint stud from the Steering Knuckle. After taking off the lower Control Arm nuts which feature 15-series washers you can extract the lower Control Arm bolts. Repeating this sequence applies to removing the lower Control Arm nuts and installing 25/35-series washers before removing the lower Control Arm bolts. Attach the new lower Control Arm by using 15-series bolts alongside 25/35-series bolts and ensure the washers face the arm shoulder. Use 150 nm (110 ft. Lbs.) torque when tightening the lower Control Arm retaining nuts before putting the wheel drive shaft back in place. Hook up the lower ball joint stud to the Steering Knuckle through its nut while tightening it to 100 nm (74 ft. Lbs.). Install the torsion bars first and then fix the shock absorber lower nut and bolt while adding stabilizer shaft links to the lower Control Arm subsequently. Rt replace tire and wheel afterward before removing safety stands and lowering vehicle for alignment work.

To replace the lower Control Arm on a 4wd vehicle, one should firstly lift and support the vehicle, remove the tire and wheel. Next, you remove the stabilizer shaft links from the lower Control Arm; then, the shock absorber lower nut and bolt. Take out the torsions and provide the wheel drive shaft. Next, remove the lower ball joint retaining nut and lower ball joint stud and Steering Knuckle bushing with j 43631 ball joint remover (J 43631) and j 45851 ball joint separator protector adapters (J 45851). Proceed to disconnect nuts of the lower Control Arm with Control Arm bolts and washers (15-series), followed by the lower Control Arm nuts, washers (25/35-series) and the lower Control Arm. For installation, locate the new lower Control Arm and attach it using the 15-series bolts, 25/35-series bolts, washers with shoulder to be next to the arm. Cross-thread the retaining nuts and tighten them to 175 nm (129 ft. Lbs.) after reinstalling the wheel drive shaft, and then connect the lower ball joint stud into the Steering Knuckle while tightening with a retaining nut to 100 nm (74 ft. Lbs.). Reinstall the torsion bars, shock absorber lower nut and bolt along with the stabilizer shaft links at the lower Control Arm. Finally adjust and realign the vehicle as needed and take off the safety stands, lower the vehicle and install the tire and wheel again.

Raise the vehicle before you support it with proper equipment while you remove both tire and wheel. Start by detaching the stabilizer shaft links from the lower Control Arm before removing the shock absorber's lower bolt and nut. To proceed with this repair first remove the torsion bars and wheel drive shaft followed by lower ball joint retaining nut removal. The j 43631 ball joint remover working together with j 45851 ball joint separator protector adapters will remove the lower ball joint stud from the Steering Knuckle for replacement. Start by removing the lower Control Arm nuts together with the 15-series washers before moving on to the lower Control Arm bolts. Continue with the lower Control Arm nuts followed by 25/35-series washers and finish by taking out the lower Control Arm bolts. Lock down the new lower Control Arm first using 15-series bolts before attaching the 25/35-series bolts while directing the washers to face the arm section. After installation of the lower Control Arm retaining nuts follow up with a tightening torque of 175 nm (129 ft lbs.). The wheel drive shaft should be reintalled then the Steering Knuckle's lower ball joint stud can be fastened before tightening the retaining nut to 100 nm (74 ft. Lbs.). The repair ends by placing the torsion bars and shock absorber lower nut and bolt in position followed by attaching the stabilizer shaft links to the lower Control Arm and installing wheel and tire assemblies while removing safety stands and lowering the vehicle before running an alignment check.
