Installationsvejledning
Installation of the differential mount requires mechanical aptitude and appropriate tools. If you are unsure about any step, consult a qualified automotive technician.
Nødvendige værktøjer og materialer:
- Topnøglesæt
- Momentnøgle
- Køretøjslift eller donkrafte
- Penetrerende olie (valgfrit)
- Stålbørste (valgfrit)
Procedure:
- Klargør køretøjet: Safely lift and support the vehicle on a level surface. Ensure the rear differential is accessible.
- Locate the Old Mount: Identify the existing rear lower rearward differential mount. It will typically be bolted to the differential housing and the vehicle's subframe.
- Support the Differential: Use a transmission jack or suitable support to slightly relieve pressure on the differential mount. This will prevent the differential from dropping once the old mount is removed.
- Fjern gammel montering: Carefully unbolt the old differential mount from both the differential and the subframe. Note the orientation of the old mount for correct installation of the new part.

- Installer ny montering: Position the new Dorman 905-539 differential mount in place. Align the bolt holes and hand-tighten the bolts.
- Momentbolte: Refer to your vehicle's service manual for the correct torque specifications for the differential mount bolts. Tighten all bolts to the specified torque. Do not overtighten.
- Endelig kontrol: Double-check all connections to ensure they are secure. Remove the differential support and safely lower the vehicle.
Driftsmæssige overvejelser
Once installed, the differential mount functions passively to support the differential and dampen vibrations. There are no operational controls for this component.
After installation, it is recommended to drive the vehicle for a short period and listen for any unusual noises or vibrations. A properly installed differential mount should contribute to a smoother and quieter drivetrain operation.
Opretholdelse
The Dorman 905-539 differential mount is designed for long-term durability. Regular inspection is recommended as part of routine vehicle maintenance.
- Visuel inspektion: Periodically inspect the differential mount for signs of wear, cracking, tearing of the rubber, or corrosion on the metal components.
- Tjek for løshed: Ensure all mounting bolts remain tight. If any looseness is detected, re-torque to vehicle manufacturer specifications.
- Address Fluid Leaks: If you notice any fluid leaks from the differential itself, address them promptly, as leaking fluids can degrade rubber components over time.
