Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands, pry bar.
Raise the vehicle with a jack and secure it on jack stands.
Inspect struts and shocks for leaks or physical damage.
- If damaged, proceed to replace.
Remove the strut assembly bolts using the socket set.
Replace worn bushings or strut mounts if necessary.
- Torque new strut bolts to manufacturer specifications (typically around 50-70 ft-lbs).
Reassemble the strut assembly and lower the vehicle.

3. Check and Secure Exhaust Components

Tools Required: Wrench set, exhaust hanger removal tool.
Inspect exhaust hangers and brackets for looseness or breaks.
Tighten or replace any loose or broken hangers.
Ensure that there is no contact between the exhaust and the chassis.

4. Examine Drivetrain Components

Tools Required: Socket set, torque wrench.
Inspect CV joints and driveshaft for play.
If any CV joint is worn, replace it as follows:
- Remove the wheel and brake assembly.
- Detach the axle nut and remove the CV joint from the hub.
- Install the new CV joint and torque the axle nut to specifications (typically around 100-120 ft-lbs).
