Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick; pull it out and wipe it clean.
Insert the dipstick back in, then remove it again to check fluid level and condition.
If fluid is low, add the manufacturer-recommended transmission fluid.
If fluid is dirty or burnt, drain the transmission fluid and replace it.
- Drain plug: Remove using a socket wrench.
- Replace with new fluid as per manufacturer specifications (typically around 4-6 quarts).
- Torque the drain plug to the manufacturer's specification (usually around 15-20 ft-lbs).

3. Inspect and Replace Serpentine Belt

Locate the serpentine belt and visually inspect for cracks or fraying.
If damaged, release tension using a belt tensioner tool and remove the belt.
Install a new serpentine belt following the routing diagram under the hood.
Ensure proper tension on the new belt.

4. Inspect Wheel Bearings

Jack up the vehicle and remove the wheel.
Grab the hub and check for excessive play by rocking it back and forth.
If bearing is worn, replace it by removing the hub assembly and pressing in a new bearing.

5. Check Differential Fluid (if applicable)

Locate the differential fill plug and remove it using a socket wrench.
Check the fluid level; it should be just below the fill hole.
If low or dirty, drain the differential fluid and refill with the specified gear oil (typically 75W-90).
Torque the fill plug to the manufacturer's specification.
