Jeep Grand Cherokee Engine Mount Guide (2000-2006)
Stop the shaking and vibrations in your Grand Cherokee by choosing the right replacement engine mounts.
- The 2000-2004 (WJ) and 2005-2006 (WK) models use different engine mounts; verify your year and engine before buying.
- Symptoms of failure include intense vibration, clunking noises on acceleration, and visible engine movement.
- It is strongly recommended to replace both engine mounts at the same time, and consider replacing the transmission mount as well.
- Jeep-specific brands like Crown or Omix-Ada are generally considered a quality middle-ground between budget and OEM parts.
Understanding the 2000-2006 Grand Cherokee Split
This year range covers two different generations of the Jeep Grand Cherokee, and they do not share the same engine mounts. It is critical to order parts for the correct generation.
- 2000-2004 (WJ): Models from these years are the "WJ" generation. They came with either the 4.0L inline-6 or the 4.7L V8 engine.
- 2005-2006 (WK): Models from these years are the first of the "WK" generation. They had options for a 3.7L V6, 4.7L V8, or 5.7L HEMI V8.
Always confirm your vehicle's year and engine before purchasing to ensure you get the correct mounts.
Symptoms of a Failed Engine Mount
When an engine mount fails, the engine is no longer held securely. This leads to several noticeable symptoms. The most common sign is a significant increase in vibration felt in the steering wheel, seats, and floor, especially when the vehicle is idling or in gear. You may also hear loud clunking, thumping, or banging noises from the engine bay during acceleration, braking, or when shifting gears. In severe cases, you can physically see the engine lurch or twist when someone revs it while the vehicle is in park. Some Grand Cherokee models use hydraulic (fluid-filled) mounts; when these fail, they can leak a brown, oily fluid onto the components below.
A Note on Safety
While you can drive with a failing engine mount, it's not recommended for long. Excessive engine movement can put stress on and damage other components, including radiator hoses, wiring harnesses, and exhaust parts. It's best to get them replaced as soon as possible.
Choosing the Right Aftermarket Engine Mount
Not all aftermarket brands are created equal. For a part like an engine mount, which is subject to constant stress and vibration, quality matters. Aftermarket mounts for the Grand Cherokee generally fall into a few categories:
- Jeep Specialist Brands (Good): Brands like Crown Automotive and Omix-Ada focus specifically on Jeep parts. Forum users generally consider them to be a good balance of quality and price, often fitting better than generic brands. They are a solid choice for daily driving and light off-road use.
- Standard Replacement Brands (Okay): Brands like Anchor, DEA, and Westar are widely available and budget-friendly. While they will work, some users report they are made with less rubber and may not last as long or absorb vibrations as well as OEM or specialist brands. They can be a good option if you're on a tight budget.
- Performance Brands (Heavy-Duty): For serious off-roading or high-performance applications, brands like Ironman4x4Fab offer heavy-duty mounts with stiffer bushings. These provide excellent durability and engine control but will transmit more vibration into the cabin, making for a harsher ride.
Pro Tip: Replace in Pairs
It is highly recommended to replace both engine mounts at the same time. If one has failed, the other has been subjected to the same age and stress and is likely not far behind. Many owners also choose to replace the transmission mount at the same time for a complete refresh of the drivetrain support system.

Searches for the 2000-2006 model years did not reveal any specific recalls or widespread Technical Service Bulletins (TSBs) from the NHTSA for engine mount failure. However, TSBs for later models indicate that vibration at idle is a known symptom addressed by updated mount designs, highlighting the importance of this part for ride quality.

Frequently Asked Questions
How many mounts does my Grand Cherokee have?
Your Grand Cherokee has two engine mounts (left and right) and one transmission mount that work together to support the engine and transmission.
Are the left and right engine mounts the same part?
No, for both the WJ and WK generations, the left (driver side) and right (passenger side) mounts are typically different parts with unique part numbers. You must order the correct one for each side.
Can I replace engine mounts myself?
Yes, this is a feasible DIY job for someone with mechanical experience and the right tools. It requires safely supporting the engine with a hoist or a jack and a block of wood while you unbolt and replace the mounts. If you are not comfortable lifting and working under a heavy engine, it is best to leave this job to a professional mechanic.
🎬 Watch: How to safely lift the engine for mount replacementWhich mount fails first?
Due to the engine's rotational torque, the passenger-side (right) mount is often the first to fail. However, it's still best practice to replace both at the same time.

The 2000-2006 year range covers two distinct vehicle generations: the WJ (1999-2004) and the WK (2005-2010). The WJ models primarily use solid rubber or hydraulic mounts for the 4.0L and 4.7L engines. The WK models introduced new engine options (3.7L, 5.7L) and feature different mount designs, some of which are hydraulic. Left and right side mounts are not interchangeable.
