MIRROR ADJUSTMENT & POWER FOLDING
Door-mirror grease: glass adjustment & power folding
Separate mirror-glass adjustment from power folding. Review lubrication of reduction gears, worms, arc teeth and supports through polymer compatibility, cold starts, noise, torque and durability.
Door-mirror lubrication review
- Contact
- Adjustment or folding, contact materials and application point/dose
- Compare
- Current lubricant, lowest starting temperature, torque and noise
- Evaluate
- Use matching doses and locations; inspect motion and components after cycling
Confirm suitability and approval through actual-part testing against the specified requirements.
Separate glass adjustment from power folding
In a common two-motor design, separate drives adjust the glass vertically and horizontally. The power-fold drive rotates the mirror head relative to the base. The arrangement and integration of the mechanisms vary by component design.

SELECTION IN CONTEXT
Can mirror adjustment and power folding use the same grease?
Assess a common grease against the materials, functions and torque limits of both adjustment and folding. Evaluate gear meshes, shafts/guides and functional friction contacts separately.
Match the contact, condition and evidence
Define the differences between contacts before comparing candidate materials.
| Contact | Selection & evaluation | Record |
|---|---|---|
| Adjustment gears & arc teeth | Identify working tooth contacts and mating materials; compare polymer compatibility, smooth motion and noise. | Polymer grade, tooth contacts, operating angle and application point/dose |
| Folding worm & gears | Review cold starts, operating current/torque, tooth condition and lubricant condition after cycling. | Minimum temperature, load, current/torque and cycles |
| Folding pivot & glass supports | Review lubrication at shafts/guides alongside the separate functions of holding and positioning. | Contact materials, clearances, drag, holding and post-cycle condition |
| Functional friction contacts | Follow the design for whether lubrication is required and compare drive/slip torque with the specification; do not indiscriminately reduce required friction. | Contact function, specified material/dose and drive/slip torque |
How to compare candidates
Separate adjustment and folding
Use the drawing or photos to identify working contacts, application points and surfaces that must remain unlubricated.
Define materials and targets
Record the current material, minimum temperature, noise, operating current/torque and cycles.
Compare assemblies with controlled dosing
Compare candidates at matching locations/doses and review cold starts, post-cycle motion and component condition.
Application questions
Should the whole moving assembly be coated?
Control application at the contacts and doses specified by the design. Review migration, contamination of electrical contacts and effects on holding or clutch functions.
Is a quieter mirror drive enough for approval?
Compare cold starts, current/torque, positioning, holding and post-cycle condition as well as noise. Review polymer compatibility and changeover from the current material.
What should be supplied for an enquiry?
Share whether the drive adjusts or folds, a photo or drawing, contact materials, current lubricant, the issue and known temperature/test conditions.
Narrow the material choice using the actual assembly
Contacts in one mirror can have different materials and functions. Use the actual parts, current material and requirements to review grade-specific records and plan sample testing.
Discuss the adjustment or folding conditions
Start with the component and issue. The form opens with this mirror application selected.
Sample comparison checklist
- Contacts
- Separate adjustment gears from the folding drive and pivots.
- Comparison
- Contact materials, current lubricant, starting temperature and dose.
- Record
- Operating/slip torque, noise and condition after cycling.
Compare on the actual part under matching conditions; discuss sample quantity and the evaluation method.
