Some Speedster have bolts through the front hubs. Normally there are drive shafts that go through the hubs on a front wheel drive car. If those bolts are not there, then the bearing won't be under pressure (normally a drive shaft is tightened with 200-300Nm). There is no danger, but when using the car more on the circuit, it is better to put these bolts in.

The parts you need to do this are:

Part Qty Part number

BOLT,M16 X 100,HUB TO HUB CARRIER 2 48 00 829 WASHER,M16 X 30,HUB TO HUB CARRIER 2 48 00 798 SHIELD,WHEEL BEARING,INNER 2 48 00 805 WASHER,THRUST,HUB,INNER 2 48 00 787 WASHER,THRUST,HUB,OUTER 2 48 00 786 NUT,HEX.,SELF LOCKING,M16,HUB RETAINING 2 48 00 793

And that amounts to a pile of steel :).

For starters first jack up the car and take off the wheel.

Then grease up the bolt.

add a big washer and grease up

add the second washer and grease up

put the bolt with washers through the hub

put the final washer on (with grease ofcourse)

get your torque wrench out and put it at 210Nm (end of the scale for mine, not very acurate, but should be near enough)

put a bit of grease on the nut

put the torque wrench on and try and get it to 210Nm (put a spanner on the bolt head ofcourse).

That's it. Put the wheel back on and do the other side. Job done.
