my Toyota Highlander shakes when I accelerate, what could be causing it?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery if required for electrical components.

2. Tire and Wheel Inspection

• Remove wheel covers if present.
• Use a socket set to loosen and remove the lug nuts.
• Inspect tires for uneven wear or bulges; replace if necessary.
• Check wheel balance and align if needed; consider professional alignment if out of spec.

3. Engine and Transmission Mount Replacement

• Locate the engine and transmission mounts.
• Use a jack to support the engine/transmission if necessary.
• Remove bolts attaching the mounts using a socket set.
• Replace with new mounts, ensuring proper alignment.
• Torque bolts to manufacturer specifications (check service manual for specific torque values).

4. Driveshaft and CV Joint Inspection/Replacement

• Inspect the driveshaft for any visible damage or rust.
• Check CV joints for torn boots or excessive play.
• If damaged, remove the driveshaft by loosening the bolts connecting it to the differential and transmission.
• Replace the driveshaft or CV joint with a new component and ensure proper installation.
