1. Check tire pressure and inflate to manufacturer specifications.
2. Inspect tires for uneven wear patterns or visible damage.
3. If needed, balance the tires using a tire balancing machine.

2. Suspension Component Check

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Visually inspect control arms, bushings, and struts for signs of wear or damage.
3. Replace any worn or damaged components with OEM parts.

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for bends or cracks.
2. Check CV joints for torn boots or excessive play.
3. Replace any damaged driveshaft or CV joint as necessary, ensuring proper torque settings on all fasteners.

4. Engine and Transmission Mounts

Sub-steps:
1. Inspect engine and transmission mounts for cracks or excessive wear.
2. If mounts are compromised, remove the old mounts and install new ones, ensuring all bolts are torqued to specifications.

5. Fluid Inspection

Sub-steps:
1. Check transmission fluid level and condition, topping off or replacing fluid as necessary.
2. Inspect rear differential fluid; change if it appears burnt or contaminated.
