Editing Replace wheel bearings (section)

====Installation====

* Using some coarse sandpaper on a fabric backing (eg. grit 60-80) work on the opening of the upright where the bearing pack sits to remove all of the rust and dirt buildup
* Clean out the bolt holes
* Clean and de-grease surfaces properly so no grit and dirt is present anymore
* Apply some anti-seize (eg. ceramic grease) along the edge of the hole so the new bearing pack will seat properly and can be removed easier later.
* Offer up the new bearing pack to the upright
* Depending on tolerances it may slide into place immediately or need pulling in by using the bolts (this seems to vary)
* If the original bolts are OK, insert these from the back of the upright and tighten them finger-tight
* Swivel upright to it's (more or less) perpendicular to car
* Using a torque wrench do up the bolts in a circular pattern until they are all tightened to 90Nm
* Check that the bearing pack sits flat and true on the upright

* Clean and de-grease the splined end of the driveshaft and make sure no dirt or grit is present
* Apply some anti-seize grease lightly to splines and mating surface of driveshaft
* Undo upper plinth bolts again
* Swivel and tilt the upright so the splined end of the driveshaft can be inserted into the bearing

* Re-fit camber shims and bolts holding upper mounting plinth to upright
* Use a torque wrench to tighten the bolts to 45Nm (8.8 grade bolts) or 60Nm (10.9 or 12.9 grade bolts)

* Re-fit trackrod and washers
* Torque nut of outer trackrod joint to upright (OEM spec nut and balljoint 74Nm, aftermarket, see supplier docs) 

* Re-connect speed sensor plug  if required


* Push the driveshaft fully through the hub so it seats properly
* Install washer and castellated nut 
* Use a torque wrench to tighten the castellated nut to 220Nm (if this turns the driveshaft/engine, wait until caliper re-fitted)
* Insert split pin that secures castellated nut on driveshaft and hammer ends over to secure it


* Clean brake disc inner mating surface to hub
* Install brake disc on hub
* Install M5 allen bolt holding brake disc on hub

* Push/screw brake caliper piston back
* Install caliper with inner pad in place (may need to replace P-clip for brake line if undone earlier)
* Refit allen-bolt and M10 bolt holding caliper to upright
* Use a torque wrench to tighten allen bolt to 28Nm and M10 to 45Nm
* Re-fit outer pad, spring and locking pin
* Apply brake pedal a few times to re-seat brake pads/pistons
* Apply handbrake
* If you were unable to set the correct torque on the center nut, try again now.
* Re-fit wheel

All Done!
