Nissan Maxima Motor Mounts

Over time, as you drive you Nissan Maxima over uneven roads and highways that are full of bumps and potholes, your vehicle will experience wear and tear that will require replacing parts. This applies not only to constantly moving parts such as wheels, brakes, and everything under the hood but also non-moving parts like the motor mounts that keep your engine securely in place within the front end framework on your Nissan. If you have been experiencing loud motor noise while idling or excessive vibration in the pedals, steering wheel, and shifter, then your Nissan Maxima motor mounts need replacing.

What is the structure of a motor mount?

There are a number of different types of motor mounts for your Nissan Maxima, but they all share a common structure. There is the motor mount itself, which is bolted to the engine and will have some sort of noise and vibration reducing material affixed to it, a bracket mounted to the frame of your vehicle that the mount will bolt into, and the nuts and bolts that hold them together.

  • Rubber motor mounts: The most common types of motor mount have rubber sleeves that bridge the gap between the steel of the engine and frame. Sound and shuddering from all the moving parts under the hood are absorbed by the material dampening their impact on your car. However, there is some allotment for some movement that will slightly reduce the amount of power sent to the drive train.
  • Polyurethane motor mounts: For those looking for a bit more of a high-performance option, there are polyurethane engine mounts. The material is stiffer than rubber and allows for less movement from the motor translating into higher performance. What you gain in performance is counterbalanced by more sound and shuddering felt inside your Nissan Maxima.
  • Solid motor mounts: If your goal is to make your Nissan Maxima race ready, then a good option might be solid engine mounts. They have no buffering material, meaning that it is metal-on-metal contact. This will hold the motor in place with the least amount of flex.
  • Hydraulic motor mounts: If it's a completely silent and smooth ride you want, then hydraulic mounts offer an interesting option. They have a hollowed-out chamber that is filled with glycol or hydraulic fluid, which is efficient at mitigating sound and shuddering. These engine mounts are usually used on vehicles with smaller engines as they tend to move around more in the frame.
What is the difference between OEM and aftermarket motor mounts?

A big factor you will need to decide when replacing motor mounts is to go with Original Equipment Manufacturer or OEM parts or to purchase aftermarket parts. The former are parts that come straight from Nissan and are constructed specifically for your Maxima while the latter is made by other third-party companies and tend to have replacement parts that are universal when it comes to different makes and models of car. Each one has positive and negative points, so the decision is yours to figure out which brand of motor mount will fall in line with your needs.
