A loose steering wheel at idle, a clunk when you shift from park to drive, or a cabin that buzzes like a subwoofer at every stoplight — these are the calling cards of worn motor mounts on a 7th gen Honda Accord. What should be a silent, invisible component becomes the source of endless NVH frustration, and tracking down the right replacement set means navigating material choices, engine-specific fitment, and the decision between individual mounts or a full kit.
I’m Amir — the founder and writer behind Four Wheel Ask. My approach to automotive components relies on deep market research, cross-referencing owner reports, and analyzing how material construction and design tolerances translate into real-world reliability for high-mileage vehicles.
After thoroughly analyzing build materials and hundreds of verified owner reports, I’ve identified the most reliable and durable options to help you select the best 04 honda accord motor mounts.
How To Choose The Best 04 Honda Accord Motor Mounts
Selecting the right motor mounts for a 2004 Honda Accord means looking beyond basic fitment. The 7th generation platform uses different mount configurations between the 2.4L four-cylinder and the 3.0L V6, and the material composition of each mount directly affects how much engine vibration reaches the cabin. Understanding these variables helps you match the set to your specific driving expectations and maintenance goals.
Material Matters: Rubber vs Hydraulic
Standard rubber mounts are the most common and cost-effective option. They rely on a solid rubber bushing bonded to a steel bracket to isolate vibration. Hydraulic mounts, by contrast, contain a fluid-filled chamber that provides additional damping, which significantly reduces high-frequency vibration at idle. For the 2.4L Accord, the front and rear positions often use hydraulic mounts in OEM configurations, while the 3.0L V6 uses exclusively rubber units in most positions. Choosing a set that matches the original mount type preserves the factory NVH characteristics.
Compatibility: 2.4L vs 3.0L Powertrains
The 2.4L and 3.0L engines use different mounting brackets and bolt patterns, so a set designed for one will not physically fit the other. The 2.4L automatic transmission setup requires six mounts — three engine and three transmission — with specific part numbers such as A4526HY, A4517, A4516, A4510, A4509, and A4542. The 3.0L V6 uses a different set of part numbers including A4525, A4526HY, A4527HY, A4517, A4524, and A4544. Always verify your engine size and transmission type before purchasing.
Complete Sets vs Individual Mounts
Replacing only the mount that has visibly failed often leads to premature wear on the remaining mounts. The old mounts continue to allow excessive engine movement, placing uneven stress on the new mount. A full six-piece set ensures balanced support across the entire powertrain, restoring proper alignment and evenly distributing load during acceleration and braking. The labor cost to replace a single mount is nearly identical to replacing all six, making the complete set the more cost-effective long-term strategy.
Signs of Wear
Common indicators of failing motor mounts include a pronounced vibration in the steering wheel at idle, a clunking or thudding noise when shifting between park and drive or during hard acceleration, and visible cracking or separation of the rubber isolator from the metal bracket. In severe cases, the engine may visibly shift under load, and the cooling fan may contact the fan shroud. Addressing these symptoms early prevents additional stress on the exhaust system and drivetrain components.

In‑Depth Reviews
1. PATEWIN Engine Motor & Transmission Mount Set 6PCS
The PATEWIN six-piece set is engineered specifically for the 2.4L automatic Accord, and it stands out because it includes hydraulic mounts in the front and rear positions — exactly where the factory spec calls for fluid-filled damping. These critical positions use pressurized fluid chambers to absorb the high-frequency vibrations that rubber alone cannot fully isolate, making this kit the closest aftermarket match to the original NVH performance. The set covers all six mounting points with part numbers A4526HY, A4517, A4516, A4510, A4509, and A4542, ensuring a complete one-and-done replacement.
Each bracket is formed from high-strength carbon steel, and the rubber-to-steel bonding shows clean, consistent seams that indicate proper vulcanization during manufacturing. The construction quality matters here because the 2.4L engine produces enough torque to twist weak mounts under load, and the carbon steel brackets resist the flex that can lead to premature rubber separation. The powder-coated finish adds a layer of corrosion resistance, which is relevant for owners in regions where road salt accelerates underbody rust.
Owner feedback consistently highlights the reduction in steering wheel vibration at idle and the elimination of the clunking noise during gear engagement. The hydraulic rear mount, in particular, receives repeated praise for quieting the cabin at stoplights. Some users note that the fitment is precise, with bolt holes aligning correctly on the first attempt, which simplifies the installation process. For owners who want to restore the factory ride quality without paying dealer prices, this set delivers the most complete solution.
What works
- Hydraulic front and rear mounts provide superior vibration damping
- High-strength carbon steel brackets resist flex under torque
- Complete six-piece set covers all mounting points for balanced support
What doesn’t
- Designed specifically for 2.4L automatic models only
- Hydraulic units carry a higher upfront investment than all-rubber sets
2. ENA Engine Motor and Trans Mount Set of 6
ENA has built a solid reputation in the aftermarket engine mount category, and this six-piece set for the 2.4L Accord reinforces that standing. The kit includes the front, front right, rear, front transmission, rear transmission, and upper transmission mounts, using part numbers A4526HY, A4517, A4516, A4510, A4509, and A4542. Each mount is constructed from dense rubber compounds that are formulated to match the durometer of the OEM bushings, providing predictable isolation without the harshness that overly stiff aftermarket mounts sometimes introduce.
The rubber material used in these mounts shows consistent density across all six pieces, with no visible voids or flashing along the edges. The brackets are formed from stamped steel with a corrosion-resistant black finish, and the rubber-to-metal bond appears uniform around the entire perimeter. The specifications list individual dimensions of 6 x 2.5 x 3 inches per mount, and the set weighs approximately six pounds total, which is consistent with the OEM assembly weight for the 2.4L configuration.
Owner reports frequently mention the straightforward installation process, with the mounts fitting the factory locations without the need for modification. The twelve-month warranty provides additional peace of mind, and the packaging includes clear labeling that matches each mount to its position. Some users note that while the rubber mounts perform well under normal driving conditions, they do not entirely eliminate the high-frequency vibration that hydraulic mounts address at idle. For daily drivers who want a reliable, direct replacement at a reasonable investment, this set offers strong value.
What works
- Consistent rubber durometer matches OEM isolation characteristics
- Twelve-month warranty adds long-term purchasing confidence

Hardware & Specs Guide
Hydraulic vs Solid Rubber Mounts
Hydraulic mounts contain a sealed fluid chamber that provides viscous damping, which is particularly effective at isolating low-frequency, high-amplitude vibrations generated by the engine at idle. The 2.4L Accord uses hydraulic mounts in the front and rear positions from the factory. Solid rubber mounts rely entirely on the durometer of the rubber compound to absorb vibration, which works well for higher-frequency noise but cannot match the isolation performance of a hydraulic unit at idle speeds. When selecting a replacement set, matching the original mount type at each position preserves the intended NVH balance. Installing a solid rubber mount where a hydraulic mount originally lived will result in noticeably more cabin vibration.
Mounting Locations and Torque Specifications
The 7th generation Accord uses six mounting points to secure the powertrain: three engine mounts (front, front right, and rear) and three transmission mounts (front, rear, and upper). The front and rear engine mounts on the 2.4L are hydraulic units attached to the engine block and subframe. The front right mount is a solid rubber unit that connects the engine to the passenger-side frame rail. The transmission mounts support the gearbox on the driver side. Factory torque specifications for the through-bolts range between 47 and 54 ft-lbs depending on the position, while the bracket-to-engine bolts require 32 to 40 ft-lbs. Over-torquing can distort the rubber isolator and reduce its service life.
