Use a pry bar to gently lift the engine, removing the old mount.
Install the new engine mount, ensuring it is aligned correctly.
Torque the bolts to the manufacturer’s specifications.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Inspect the driveshaft for any visible damage or excessive play.
Check CV joints for torn boots or grease leakage.
Replace any damaged components with new parts, ensuring proper alignment during installation.

5. Spark Plug and Ignition System Check

Tools Required: Socket set, spark plug gap gauge.
Remove the spark plugs and inspect them for wear or fouling.
Check and adjust the gap on new spark plugs according to specifications before installation.
Inspect ignition coils and wires for damage, replacing as necessary.
