Overview
What Is an Infiniti Engine Mount Replacement?
Infiniti engine mount replacement is the removal and substitution of failed or degraded engine mounting assemblies that secure the engine and transmission to the vehicle's subframe and body structure. Engine mounts perform 3 simultaneous mechanical functions: supporting the engine's static weight, absorbing the dynamic torque reaction forces generated during acceleration and braking, and isolating the engine's operational vibration from the vehicle cabin.
Abu Dhabi operating conditions accelerate engine mount deterioration through 2 mechanisms specific to the region. Ambient temperatures consistently reaching 50°C between May and September cause the rubber compound used in standard mount bushings to oxidize and harden progressively, reducing the mount's ability to absorb vibration from a shore hardness of 55 at installation to above 85 within 4 to 6 years of UAE operation.

8 Infiniti Engine Mount Replacement Services at Zenfo Auto Services
Infiniti Engine Mount Diagnostics
Engine mount diagnosis begins with a 3-stage assessment covering all mount assemblies. The first 2 stages include a visual inspection for rubber cracking, fluid leakage, and metal bracket corrosion, and a static load test measuring deflection against the manufacturer maximum specification.
Infiniti Rubber Engine Mount Replacement
In stage 1, the rubber compound hardens from the UAE heat exposure, reducing vibration absorption. In stage 2, micro-cracking develops at the rubber-to-metal bond interface. In stage 3, the rubber core separates from the metal bracket.
Infiniti Hydraulic Engine Mount Replacement
Hydraulic engine mounts on VQ37VHR models use a sealed fluid-filled chamber connected to an orifice plate that varies hydraulic resistance in response to vibration frequency, providing superior low-frequency vibration isolation compared to rubber mounts.
Infiniti Active Hydraulic Mount Replacement
Active hydraulic mounts on the VR30DDTT twin-turbo engine use an electronically controlled solenoid valve that adjusts internal fluid orifice diameter in response to commands from the Active Noise Control module.
Infiniti Transmission Mount Replacement
Transmission mount failure on QR25DE and VQ35DE models produces a clunk specifically during the transition between drive and reverse gear engagement, a symptom that owners frequently misidentify as a transmission fault.
Infiniti Engine Mount Bracket Repair
Engine mount steel brackets on VK56VD models develop corrosion at the mount-to-subframe interface from the combination of salt air exposure on Abu Dhabi coastal roads and the elevated surface temperature of the subframe.
Infiniti Engine Mount Post-Replacement Alignment Check
Engine position alignment verification is performed following every engine mount replacement at the Mussafah workshop, confirming the engine has returned to the manufacturer's specified position within the engine bay.
Infiniti Engine Mount Vibration Validation
Post-replacement vibration validation is performed at the Mussafah workshop using a digital vibration analyser measuring cabin vibration amplitude in 3 axes at idle, 1,500 RPM, 2,500 RPM, and 3,500 RPM.
Common Faults
6 Most Common Engine Mount Faults Diagnosed at Zenfo Auto Services
6 engine mount faults recur most frequently across UAE-registered Infiniti models:
VQ35DE Right Engine Mount Rubber Debonding
Right engine mount rubber debonding on VQ35DE engines above 90,000 km produces a clunk during throttle application from rest and a vibration at idle transmitted through the steering wheel. Static deflection measurement above 8mm confirms core separation.
VQ37VHR Left Hydraulic Mount Fluid Loss
Hydraulic fluid loss from the left engine mount on VQ37VHR engines in the G37 and Q60 produces idle vibration transmitted to the steering wheel at traffic stops, confirmed by static deflection above 2mm.
QR25DE Transmission Mount Core Separation
Transmission mount core separation on QR25DE engines in the QX50 and EX35 produces a clunk specifically during drive-to-reverse and reverse-to-drive gear changes. Pry bar deflection measurement above 6mm confirms core separation.
VR30DDTT Active Mount Solenoid Failure
Active mount solenoid failure on VR30DDTT engines in the Q50 Red Sport produces fault code P1448 and a highway cruise vibration between 1,800 and 2,200 RPM. OEM software live data confirms the solenoid is not responding.
VK56VD Front Mount Collapse Under Load
The front engine mount rubber collapse on the VK56VD V8 in the QX80 above 100,000 km produces a pronounced clunk during hard acceleration and visible engine movement, confirmed by video inspection during a controlled throttle blip.
VQ Engine Mount Bracket Stress Fracture
Mount bracket stress fracture on VQ35DE and VQ37VHR models produces intermittent engine movement that varies with temperature, as thermal expansion partially closes the fracture under hot operating conditions and reopens it during cold starts.
Why Zenfo Auto Services
Why Infiniti Owners in Mussafah Choose Zenfo Auto Services for Engine Mount Replacement
7 measurable differences separate Zenfo Auto Services from general workshops across Abu Dhabi:
| Advantage | Zenfo Auto Services | General Workshop |
|---|---|---|
| Diagnostic Method | 3-stage assessment combining visual inspection, deflection measurement, and OEM fault scanning | Visual inspection only, with hydraulic mount fluid loss and bracket fractures frequently missed |
| Brand Specialization | Infiniti-exclusive workshop with detailed knowledge of all VQ, VR, QR, and VK engine mount configurations and active mount systems | Multi-brand workshop without capabilities for active hydraulic mount solenoid diagnosis and system reset |
| Parts Quality | Genuine OEM mount assemblies with the correct rubber compound shore hardness for each engine application | Aftermarket mounts with unverified rubber compound hardness and bracket geometry |
| Fault Accuracy | Deflection measurement confirming mount condition before and after replacement | Mount condition assessed by feel only, without measurement-based verification of correct installation |
| Vibration Validation | Digital vibration analysis confirming NVH specifications before vehicle handover | No post-replacement vibration testing, with vibration complaints often discovered after vehicle collection |
| Warranty Coverage | 12-month parts and labour warranty on all engine mount replacement work | Variable warranty terms, with 3-month parts-only coverage commonly offered |
| Pricing Structure | 25% to 40% lower than Infiniti dealership pricing with a fixed written quotation issued before work begins | Hourly billing structure with final repair cost confirmed only after job completion |
