Nissan Altima Engine Mount Brackets

Nissan Altima Engine mount brackets

Engine mount brackets for your Nissan Altima start at $27.95, with 1 options in stock from DEA. The engine mount bracket is the rigid metal frame that bolts the rubber or hydraulic engine mount to the engine block and vehicle subframe. When it cracks or breaks, the engine shifts under load, causing vibration, misalignment, and potential damage to surrounding components.

Signs your Nissan Altima needs a new engine mount bracket

  • A loud clunk or thud when accelerating, braking, or shifting gears — the engine is rocking against its remaining mounts
  • Visible cracks, bends, or fractures on the metal bracket when inspected from below
  • Excessive engine movement you can see by hand when the vehicle is in park and engine is revved
  • Vibration felt through the floor, steering wheel, or shifter that worsens under engine load
  • Rattling or banging from the engine bay over bumps or rough road surfaces
  • Premature wear or tearing of adjacent rubber mounts forced to absorb extra stress from the failed bracket

Which engine mount bracket should you buy for your Nissan Altima?

The most important decisions are whether to match OE material and position, and whether to choose a direct-fit replacement or a heavier-duty aftermarket bracket. Engine mount brackets are position-specific — front, rear, left (torque), and right side brackets are not interchangeable, so confirm the location before ordering.

OE-Spec Replacement
Best for
Daily drivers needing a factory-accurate fit
What you get
Stamped or cast steel bracket matching original dimensions, bolt pattern, and mount attachment points for a straightforward swap
Heavy-Duty / Reinforced
Best for
High-mileage vehicles or those with prior bracket failure
What you get
Thicker steel or gusseted design that resists cracking under higher stress and engine torque loads
Performance / Solid Mount Bracket
Best for
Modified or high-output engines where mount flex is unacceptable
What you get
Rigid bracket with minimal compliance, reduces engine movement at the cost of increased NVH (noise, vibration, harshness) in the cabin
Complete Mount + Bracket Kit
Best for
Vehicles where both the bracket and rubber mount are worn simultaneously
What you get
Bundled bracket and mount assembly that eliminates the guesswork of part compatibility and restores full engine support in one purchase

Replacing the engine mount bracket on a Nissan Altima

Moderate⏱ 1–3 hoursFloor jack and jack stands or a vehicle liftEngine support bar or jack with a block of wood to support the engine from belowSocket and ratchet set with extensionsBreaker bar for seized or heavily torqued fastenersPenetrating oil for corroded hardware

The engine must be safely supported — either with an engine support bar spanning the bay or a floor jack under the oil pan with a protective block — before any mount bracket hardware is removed, so the engine does not drop and pinch your hands or damage other components. Once supported, remove the bracket fasteners, swap in the new bracket, and hand-start all hardware before final tightening in the sequence recommended in your vehicle's service manual. Torque all fasteners to specification and remove the engine support before lowering the vehicle and test-driving to confirm the clunking and vibration are gone.

Frequently asked questions

How much does it cost to replace engine mount brackets on a Nissan Altima?
Engine mount bracket parts for a Nissan Altima start at $27.95. The bracket itself is often the most affordable piece of the repair; total cost rises if the rubber mount, hardware, or adjacent components need replacement at the same time. DIY installation keeps overall cost closest to the part price alone.
Can I drive my Nissan Altima with a broken engine mount bracket?
You should not drive far on a broken engine mount bracket. Without proper support, the engine can shift enough to strain or snap coolant lines, brake lines, wiring harnesses, and CV axles. Short, slow trips to a shop are acceptable, but continued driving risks substantially more expensive damage to surrounding components.
Is an engine mount bracket the same as an engine mount?
No. The engine mount is the rubber or hydraulic isolator that absorbs vibration. The engine mount bracket is the rigid steel piece that physically attaches the mount to the engine block or subframe. Both must be intact to properly support the engine — a broken bracket defeats even a brand-new rubber mount.
How long does an engine mount bracket last on a Nissan Altima?
Engine mount brackets are steel and can last the life of the vehicle under normal conditions. Premature failure is usually caused by a previous collision, corrosion from road salt in northern climates, or excessive torque stress from performance modifications. Inspect the bracket any time a rubber mount or torque strut is replaced.
Do I need to replace all engine mount brackets at once on my Nissan Altima?
Not necessarily, but inspect all brackets when one fails. A cracked bracket often means another has been under increased load. Replace any bracket showing visible cracking, deformation, or heavy corrosion. Replacing only the failed bracket is acceptable when the remaining ones are confirmed to be structurally sound.
Will a bad engine mount bracket cause my Nissan Altima to fail an alignment or inspection?
A broken engine mount bracket can affect powertrain geometry enough to make proper alignment difficult or impossible, since drivetrain components shift position. Some state safety inspections specifically check engine mount integrity. Address a failed bracket before or alongside any alignment or drivetrain inspection to avoid repeat alignment problems.
