Front Upright Assembly

Westfield front uprights are based on Ford Cortina geometry. Westfield produce a bespoke cast aluminium upright, but Cortina uprights can be used, as well as other bespoke options.

Westfield front uprights are delivered as assembled units with hubs, brake discs and callipers. However, if components are purchased individually, the uprights must be assembled before fitting on the vehicle.

Assembly Steps

 * Before starting upright assembly, check the orientation of the steering arms tapers and swap arms if required.
 * The brake disc bells may be painted to prevent rusting. This should be done before upright assembly.


 * 1) Place the hub with the studs downward, on some cardboard to avoid damaging the threads (or the work surface).
 * 2) Pack the larger tapered roller bearing with grease and insert into the matching bearing race in the hub.
 * 3) Use a hydraulic press to evenly press the bearing seal into the hub with the hollow side downwards towards the bearing. The seal will not go all the way to the bearing - it seals against the spindle.
 * 4) Degrease the brake disc with brake cleaner.
 * 5) Place the brake disc on the hub with the bell downwards (hollow side up), and align the holes.
 * 6) Add the locking tabs and finger-tighten the bolts. The edges of the tabs can be bent slightly in advance to make access easier later.
 * 7) Secure the assembly (a second person can hold it still) and sequentially torque the bolts to 54Nm (40lb ft). Torque the bolts in opposite pairs, not in a circle.
 * 8) Fold up the locking tabs around the bolt heads.
 * 9) Place the upright on the work surface with the spindle upwards. If the brake disc is handed, ensure the matching upright has been selected.
 * 10) Turn over the disc-hub assembly and push it down onto the spindle.
 * 11) Pack the smaller tapered roller bearing with grease and slide into the spindle, down to the matching bearing race in the hub.
 * 12) Add the keyed washer and castellated nut. Torque to ##Nm (27lb ft), then gently back off until the split pin can be inserted.
 * 13) Lock the split pin and trim excess if necessary. Do not wrap over the top of the spibdle (this will clash with the grease cap).
 * 14) Push in the grease cap.
