Dorman Buyer Applications

Supply the OE cross reference and supersession lists with model year, drivetrain and axle position. Ask suppliers to flag any references that point to a different hub flange or ABS encoder. A single supplier simplifies revision control. Multiple suppliers can fill catalogue gaps but each quoted revision needs its own sample evidence and packing record.

Identify the replacement scope for each service operation. Where the vehicle procedure permits a serviceable bearing, specify bore, outside diameter, width, seal lip, retention and preload or endplay. An integrated hub unit can simplify field assembly, but the mounting depth, wheel speed sensor and flange must match.

Build separate lines by vehicle configuration, axle and duty cycle. For wheels, include pitch circle diameter (PCD), wheel offset (ET), center bore, rim diameter and width, load rating and finish. For tires, specify size, load index, speed rating, tread and destination. For example, 225/45R18 and load index 95 are different fields. A size match leaves load and speed checks open.

Set the drawing revision, datum, dimensional check method, acceptance criteria and sampling plan before booking inspection. For flange lateral runout, specify the mounting fixture, indicator location and full revolution. Ask the inspector to record the indicator range and sample ID, then compare the result with the buyer-approved limit.

Provide target market, destination port and unit, carton and pallet labeling requirements. Mixed-container loading needs one packing list that preserves the identity of every SKU.

Keep each cross reference beside its source and revision. Treat unresolved fitment as pending while the buyer checks vehicle applicability.
