6. Spanner Check

02.01

00:00 - The last part of our seven step process as far as the workshop component goes is to spanner check all of our work.
00:07 This is an essential part, making sure that all of the components that we've touched, modified or adjusted are correctly re tightened.
00:15 For this, we've put the car back up on the hoist and we've removed the wheels again.
00:19 And the process I like to go through here is just working from the top down.
00:23 So we're going to start by making sure that our strut tops are tightened in the chassis and that, particularly on the front, our camber adjustable strut top cap screws have also been correctly retightened.
00:35 From here, we can work down our strut.
00:37 Because we've made ride height adjustments, we need to check and make sure that the locking screw for our lower spring platform has been correctly tightened, as well as the two bolts that hold our MacPherson strut onto our hub, as well as the sway bar linkage.
00:52 From here, we can now move underneath the car and it's simply a case of rechecking every single suspension component and every single place where a suspension component mounts to the chassis.
01:05 In particular, during our toe adjustments we've loosened our tie rod ends for our front steering and we need to make sure that these are correctly re tightened.
01:14 We also need to make sure that when we tighten these, we don't inadvertently make any further adjustments, so it's important to hold one side of the tie rod and make sure that that's not going to move as we tighten the locking nut.
01:27 Lastly we need to go over all of the suspension arms that we've fitted and make sure that the cap screws that lock down the adjustment mechanism are correctly tightened.
01:37 Once we've completed this procedure at the front of the car, we're simply going to repeat the process at the rear.
01:47 With all of our components correctly tightened and checked, we can now put the wheels back on and move onto the last step of the process which is where we can evaluate our changes out on the racetrack.
