How to replace the Strut Mount
Replacing the front strut mount on your Volkswagen Jetta, Taos, or Tiguan is an intermediate-level DIY procedure. It requires basic hand tools, a quality spring compressor, and a floor jack with jack stands. Always follow safe lifting procedures and consult your vehicle's service manual for model-specific torque values before beginning.
-
Prepare the Vehicle
Park on a level surface, engage the parking brake, and chock the rear wheels. Gather all required tools including a spring compressor, socket set, torque wrench, and jack stands.
-
Remove the Front Wheel
Loosen the lug nuts with the vehicle still on the ground. Raise the front of the vehicle with a floor jack and secure it on jack stands at the manufacturer-recommended lift points. Remove the lug nuts and pull off the front wheel.
-
Access the Upper Strut Mount
Open the hood and locate the upper strut mount bolts in the engine bay strut tower. Remove any cowl panel or trim pieces that obstruct access.
-
Disconnect Strut Assembly Components
Disconnect the sway bar end link from the strut. Unclip the brake line bracket and ABS sensor wire from the strut body. Unbolt the lower strut pinch bolts at the steering knuckle and support the knuckle to prevent stress on brake and ABS lines.
-
Remove the Strut Assembly
With a helper or suitable support holding the strut from below, remove the upper strut mount bolts from inside the engine bay. Carefully lower and withdraw the complete strut assembly from the vehicle.
-
Compress Spring and Replace Mount
Secure the strut in a vise and attach a spring compressor to the coil spring. Compress the spring sufficiently to relieve load from the strut mount. Remove the top nut, then lift off the old strut mount. Install the new 5QM412331A mount, ensuring correct orientation and alignment of all components before releasing spring tension.
-
Reinstall Strut Assembly
Guide the strut assembly back into the strut tower and hand-thread the upper mount bolts. Reconnect the lower strut bolts at the steering knuckle, reattach the sway bar end link, and reinstall brake line and ABS wire brackets. Torque all fasteners to the manufacturer's specified values per your service manual.
-
Reinstall Wheel and Verify
Reinstall the front wheel and torque lug nuts to spec. Lower the vehicle, then perform a final check of all fasteners. Test drive the vehicle at low speed and listen for any abnormal noise before resuming normal driving. Schedule a wheel alignment if steering geometry may have been disturbed.
Signs of a worn part
-
Clunking or Knocking Noise
A worn strut mount commonly produces a clunking, knocking, or thudding noise from the front suspension area, especially over bumps, potholes, or during low-speed turns.
-
Excessive Vibration in Cabin
When the rubber isolator within the mount degrades, road vibrations that should be absorbed are instead transmitted through to the steering wheel, floorboard, or seat.
-
Stiff or Vague Steering
A seized or deteriorated strut mount can restrict the strut's rotation, leading to stiff, heavy, or imprecise steering response — particularly noticeable when maneuvering at parking speeds.
-
Uneven Tire Wear
A failed strut mount can allow the suspension alignment to shift, resulting in abnormal or uneven tread wear patterns that shorten tire life.
-
Visible Rubber Deterioration
Physical inspection may reveal cracked, torn, or collapsed rubber in the mount, or corrosion and deformation of the metal housing, indicating the part has reached end of service life.
Replacement intervals
Strut mounts do not have a fixed replacement mileage like consumables — service life depends heavily on road conditions, climate, and driving style. Always replace the mount when replacing struts or shocks to avoid returning to the job. Symptoms of failure should prompt immediate inspection regardless of mileage.
Frequently asked questions
Is 5QM412331A the correct part for both left and right sides?
Based on the research available, 5QM412331A is listed as a single part number covering the front strut mount application. However, some vehicles use separate left and right part numbers. Confirm correct fitment by cross-referencing your VIN with the Volkswagen parts catalog or your dealership before ordering.
Does this strut mount include the strut bearing?
No — the 5QM412331A strut mount is listed without bearing. If your bearing is also worn (a common cause of grinding or creaking during steering), you will need to source a compatible strut bearing separately.
Can I replace just the strut mount without replacing the strut itself?
Yes, if the strut body and coil spring are in good condition, replacing only the mount is a valid repair. However, since labor involved in accessing the mount is substantial, many technicians recommend inspecting and replacing the strut, spring, and mount together to maximize component life and reduce repeat labor costs.
Is the Borg & Beck FSM5485 a reliable alternative to the OEM part?
Borg & Beck (also marketed as First Line) is an established European aftermarket brand with OE-supplier heritage. The FSM5485 is listed as a direct equivalent without bearing for this application and represents a cost-effective alternative to the genuine Volkswagen part. For the highest confidence in fit and durability, the OEM 5QM412331A remains the benchmark.
Which Volkswagen models use the 5QM412331A strut mount?
This part is compatible with the Volkswagen Jetta (2019–2024) with 1.4L, 1.5L, and 2.0L engines across all trim levels including GLI; the Volkswagen Taos (2022–2024) with 1.5L engine; and the Volkswagen Tiguan (2018–2024) with 2.0L engine across all trim levels. Always verify against your specific VIN to confirm fitment.
Do I need a wheel alignment after replacing the strut mount?
Yes, it is strongly recommended. Any time front suspension components are disassembled and the strut is removed, there is potential for small changes in suspension geometry. A professional four-wheel alignment after the repair will prevent uneven tire wear and ensure proper handling and steering.
