Entity and site
If IATF 16949 or ISO 9001 evidence is requested, record the issuer, site, scope and validity. These records describe a quality management system.

MOOG Fitment & Specs
Give every quote the same application, interface and acceptance criteria. The sourcing desk coordinates the review. Buyers release the fitment decision against supplier drawings and sample evidence.
Prepare your RFQ
- Vehicle configuration, axle and OE reference
- Interface drawing, dimensions and load
- Quantity, target market and port
Fitment inputs and what to verify
Record the unit, tolerance and revision wherever a value will become an acceptance criterion. For example, 5 × 114.3 means five mounting positions on a 114.3 mm pitch circle. It leaves wheel offset and center bore unresolved, so request those dimensions before evaluating brake clearance.
| Product cluster | Request from buyer | Compare before approval |
|---|---|---|
| Wheel Hub Assemblies | OE cross reference, VIN-derived model and trim, axle, driven or non-driven position, flange drawing and mounting hardware. | Check hub flange diameter and mounting face, spline count, ABS encoder ring orientation and connector keying. For a front wheel hub assembly diagram, request pilot and flange datums on the drawing. |
| Wheel Bearings & Kits | OE reference, bore, OD and width in mm, seal type, bearing arrangement and kit scope. | Confirm the preload method and seal lip orientation. The same envelope dimensions may hide a different internal design or encoder side. |
| Forged & Cast Alloy Wheels | Vehicle, pitch circle diameter (PCD), wheel offset (ET), center bore, rim diameter and width, load rating, finish and destination market. | Check mounting interface, brake clearance and runout tolerance. Compare forged and cast options on drawing fit, sample cost and quoted lot size before using weight as a selection criterion. |
| Steel & Commercial Vehicle Wheels | Rim structure, bead seat profile, dimensions, finish, bolt pattern and maximum axle load. | Compare clamp and mounting geometry, corrosion protection and the supplier’s packing plan for the selected rim design. |
| Passenger & Commercial Tires | Size designation, load index, speed rating, tread pattern, road duty, quantity mix and destination port. | Match service description and markings to the target market. Evaluate rolling resistance alongside wet grip and tread wear for the actual duty cycle. |
| Off-Road & Specialty Tires | Size, load and speed designation, casing, terrain, cut exposure, heat cycle, tread pattern, quantity and port. | Compare the supplier’s load and speed conditions with the operating profile. Ask how the supplier proposes to protect the casings in transit. |
| Wheel-End Accessories & Service Parts | Application, part dimensions, thread pitch and seat type, material and finish, packaging and kit contents. | Check the mating interface and count hardware separately. Confirm which documents cover the exact part in the quote. |
Trace each document to the quoted part
Market and model
Identify the product and destination first. Consider UNECE, DOT/FMVSS, SAE or JWL/VIA evidence only where it applies to the part, market and requested claim.
Part traceability
Ask for the inspected SKU, revision, lot and fixture setup. Compare what was measured with what the purchase brief actually specifies.
Runout check
Specify the datum and fixture in the inspection plan. On the agreed fixture, zero the indicator at the specified radius, rotate the hub and record total indicator reading against the drawing limit.
Sample sign-off
Record vehicle configuration, drawing revision and any exceptions. An untested ABS interface stays open until the agreed verification is recorded.
Release conditions
Write down which documents and approvals are due before purchase, shipment or receiving. Assign each action to its responsible party.
