• Bearing pack with built-in speed sensor: A117D6005F

Replacment parts

Bearing units are originally made by SKF who also sell complete aftermarket replacement kits:

• SKF VKBA3511 with sensor

Both SKF kits come including:

• bearing packs
• new mounting bolts (approx 10mm too long for the Elise can be cut down)
• new castle nut for the driveshaft/CV
• new split pin for castle nut
• dust cover for center

Elise S2 ABS

Use 4 identical bearing packs, ALL with speed pulse for the ABS signal (which in turn feeds that to the ECU)
