Solution

1. Preparation

Gather tools such as a jack, jack stands, wrench set, and a transmission fluid dipstick.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Transmission Fluid Inspection

Sub-step 1: Remove the transmission dipstick and wipe it clean.
Sub-step 2: Reinsert the dipstick and remove it again to check the fluid level. If low, top up with the recommended transmission fluid.
Sub-step 3: If fluid is dark or has a burnt smell, perform a transmission fluid change.

3. Drive Belt Replacement (if needed)

Sub-step 1: Locate the drive belt tensioner and relieve tension using a wrench.
Sub-step 2: Remove the old drive belt by sliding it off the pulleys.
Sub-step 3: Install the new drive belt, ensuring it is seated correctly on all pulleys.
Sub-step 4: Reapply tension to the tensioner and check for proper alignment.

4. Engine Mount Replacement (if needed)

Sub-step 1: Lift the engine slightly using a jack with a block of wood to avoid damage.
Sub-step 2: Remove the bolts securing the faulty engine mount.
Sub-step 3: Replace with a new engine mount and torque bolts to manufacturer specifications.
Sub-step 4: Lower the engine and check for proper alignment.

5. CV Joint Inspection and Replacement (if needed)

Sub-step 1: Raise the vehicle and remove the wheel.
Sub-step 2: Inspect the CV joints for any visible damage or torn boots.
Sub-step 3: If damaged, remove the axle nut and detach the CV joint from the hub assembly.
Sub-step 4: Install the new CV joint or axle and torque the axle nut to specification.
