I have a part reference
Browse product lines
Use a supplier part number or OE cross reference to group the request by bearing, hub or service kit.
Open catalogSet up a brief suppliers can quote
- 01 · Identify
Separate confirmed OE references from candidates. Record the VIN or platform, model year, drivetrain and axle for each line.
- 02 · Describe
List dimensions and tolerances, encoder orientation, seal and hardware. Add lot marking, packaging, quantity and the market on the same line.
- 03 · Verify
Ask how the sample will be linked to the order. Agree inspection checks and make the named place, Incoterm and destination port explicit.
Five decisions to make before ordering
Send the OE reference, VIN or vehicle details, axle and side, plus bore, outer diameter and width in mm. For a double-row angular contact bearing, record the seal lip and encoder side from the applicable drawing. Ask whether the kit includes retaining hardware. If you need front wheel bearing hub assembly torque specs, identify the exact vehicle and fastening point so the applicable service information can be checked.
Start with the repair path approved for the platform. A preassembled hub can reduce assembly variables and may include the ABS encoder ring or wheel speed sensor interface. A serviceable bearing may use less replacement hardware but depends on the housing condition, fitting equipment and preload procedure. Compare hardware, labor and fitment evidence before ranking unit prices.
A single source simplifies tracking drawing changes, sample approvals and cartons. Split sourcing can cover gaps in the OE list or diversify supply. It adds supplier-specific evidence, pack and lot controls. Ask both suppliers for the same named place, Incoterm, pack quantity, inspection terms and SKU revision before comparing a split order with a single-source order.
Identify the sample SKU, lot and drawing revision. Agree the dimensions in mm, tolerance and datum, and use an agreed instrument and method. For a hub flange, record radial or lateral runout where specified. Confirm the encoder orientation and pole count against the applicable reference before evaluating the signal separately. Log the reading, setup and any deviations. The buyer decides whether exceptions can be accepted for that release.
Keep fitment and duty on their own quote lines. For wheels, include PCD, ET, center bore, rim diameter and width, finish and load rating. For tires, include the size designation, load index, speed rating, tread, use conditions and destination port. Request the relevant market evidence for the named SKU and revision so the report can be linked to the quoted line.
