Sub-step 3: If the CV joint is worn, remove the axle nut and separate the CV joint from the hub assembly.
Sub-step 4: Install a new CV joint, ensuring it is properly greased.
Sub-step 5: Reassemble the axle and wheel, tightening the axle nut to the manufacturer’s specified torque value (usually around 200 Nm).

3. Inspect and Repair Suspension Components

Sub-step 1: Remove any protective covers to access the suspension.
Sub-step 2: Check control arms, bushings, and ball joints for wear; replace any damaged components.
Sub-step 3: Tighten all suspension bolts to the manufacturer’s specified torque settings.
Sub-step 4: Reassemble any components that were removed for access.

4. Brake Inspection and Repair

Sub-step 1: Remove the brake caliper and rotor to inspect for loose or damaged parts.
Sub-step 2: Check the caliper brackets and mounting hardware; replace if necessary.
Sub-step 3: Reinstall the brake components, ensuring all bolts are torqued to specifications.
