Symptoms

•Knocking noise when accelerating or decelerating
•Noise more pronounced during turns
•Engine misfire or rough idle
•Loss of power or sluggish acceleration
•Abnormal wear on tires

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any diagnostic trouble codes (DTCs) related to the engine or transmission.
2
Check engine oil level and condition to ensure proper lubrication and identify any signs of contamination or metal shavings.
3
Inspect the suspension components visually for any signs of wear or damage, such as worn bushings or loose bolts.
4
Listen for the noise in different conditions (idle, acceleration, turning) to determine if it’s engine-related or suspension-related.
5
Examine the drivetrain components (e.g., CV joints, driveshaft) for any signs of damage or wear.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Oil

Remove the oil drain plug using a socket wrench and allow the oil to drain completely.
Inspect the oil for metal shavings or debris, which may indicate internal engine problems.
Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated.
Reinstall the drain plug and tighten to the manufacturer’s specified torque (usually around 20-25 lb-ft).
Add new oil suitable for the engine (usually 5W-20 or as specified in the owner’s manual).

3. Examine and Replace Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to gain access to the suspension components.
Inspect the control arms, bushings, and ball joints for signs of wear or damage.
Replace any worn components with OEM or quality aftermarket parts, ensuring proper torque specifications are followed during installation.
Reassemble by reinstalling the wheels and lowering the vehicle.

4. Inspect and Repair Drivetrain Components

Check the CV joints and driveshaft for any visible damage or play.
If damaged, replace the CV joints or driveshaft according to the manufacturer’s specifications.
Ensure all connections are tight and lubricated where necessary.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and listen for the knocking noise.
If the noise persists, further investigation may be required for internal engine issues.
