Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery before working on electrical components.

2. Check Transmission Fluid

Locate the transmission dipstick (usually near the engine).
Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the recommended transmission fluid (Toyota Type T-IV).
Inspect the fluid for burnt smell or debris; if contaminated, consider a fluid change.

3. Inspect Rear Differential

Raise the rear of the vehicle using a jack and secure it with jack stands.
Remove the rear differential cover bolts using a socket set.
Inspect the fluid level; if low, add differential fluid (75W-90 GL-5).
Check for metal shavings or debris in the fluid; if present, a rebuild may be necessary.

4. Examine Drive Shafts and CV Joints

Visually inspect the drive shafts for any visible damage, such as dents or bends.
Check CV joints for grease leaks or torn boots.
Rotate the drive shaft by hand to listen for unusual noises.
Replace any damaged components with OEM parts.

5. Test Drive and Reassemble

Reassemble any components removed during inspection.
Lower the vehicle and reconnect the battery.
Conduct a test drive in reverse to check if the noise persists.
