Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace CV Joints/Axles

Tools Required: Socket set, jack and jack stands, torque wrench.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV boots for tears and the joints for play.
4. If damaged, remove the axle nut and detach the CV joint from the transmission.
5. Install the new CV joint or axle by reversing the removal steps and torque the axle nut to the manufacturer's specification (typically around 150 ft-lbs).

3. Transmission Fluid Check and Replacement

Tools Required: Transmission fluid pump, new transmission fluid.
Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. Check fluid level and condition; if it’s low or dirty, proceed to change it.
3. Drain the old fluid using a transmission fluid pump.
4. Replace with the correct type of transmission fluid (usually Toyota ATF WS).
5. Run the engine and check the fluid level again, adding as necessary.

4. Brake System Inspection

Tools Required: Brake cleaner, socket set.
Sub-steps:
1. Inspect the brake calipers and rotors for wear or misalignment.
2. If the brakes are dragging, remove the caliper and clean the components with brake cleaner.
3. Replace any worn brake pads or rotors as needed.
4. Reinstall the caliper and torque the bolts to specifications.
