Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Drive Belts

Tools Required: Socket set, screwdriver, torque wrench
Instructions:
1. Remove the engine cover (if applicable) by unscrewing the securing bolts.
2. Inspect all drive belts for cracks, frays, or signs of wear.
3. If any belt is damaged, loosen the tensioner and remove the old belt.
4. Install the new belt by routing it according to the belt path diagram (usually located near the engine).
5. Re-tension the belt according to manufacturer specifications using a torque wrench.

3. Inspect and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, catch pan
Instructions:
1. Locate the transmission fluid dipstick and check the fluid level and condition.
2. If the fluid is low or dirty, drain the transmission fluid into a catch pan.
3. Replace the transmission filter if applicable, following manufacturer guidelines.
4. Refill the transmission with the appropriate type and amount of fluid using a funnel.
5. Start the vehicle and let it run to circulate the new fluid, then recheck the level.

4. Inspect Wheel Bearings and CV Joints

Tools Required: Jack and jack stands, socket set
Instructions:
1. Raise the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels to gain access to the hub assembly.
3. Inspect the wheel bearings for play or roughness by spinning them by hand.
4. Check the CV joints for any signs of damage or grease leakage.
5. If either component is worn, replace them according to manufacturer specifications.
