Step 5: Perform Alignment

02.33

00:00 - In step 5, we're ready to go ahead and make our alignment changes.
00:03 The order we do things here is important to take note of.
00:06 The first thing is to deal with the caster as it tends to have a lot of flow on effects for the rest of the wheel alignment.
00:12 In this case, the caster settings we measure in the set down are the same as our targets so they don't need any attention.
00:19 One thing to mention here in addition to keeping track of the set down and set up values, I like to record the values I measure in order as I go.
00:27 This helps me keep track of where I started and how much change I'm getting in each step.
00:31 This can be really valuable to do this so I recommend doing it as well.
00:35 Now we're ready to set our toe and camber.
00:38 These tend to affect each other to some extent, meaning making a camber change will often result in a toe change.
00:43 This means it becomes a bit of an iterative process, going around a loop of toe and camber.
00:48 Some suspensions are more sensitive to this than others.
00:52 You'll start to zero in on the settings pretty quickly and the closer you get, the less these settings will affect each other.
00:58 Starting with the front left camber, we make the adjustments on the top arm.
01:02 Jack the car up and with the car in the air, record the current camber value.
01:06 Even though this isn't a useful number in itself, it gives us a reference for how far we need to move the camber setting, by knowing how much we need to change the camber.
01:15 Cracking off the adjuster bolts in the top arm and making the adjustments by sliding the clevis in the slots, we can temporarily retighten the bolts.
01:22 Refit the wheel and measure the new camber value.
01:25 After making a second smaller adjustment, we're now at our target and for now, we're done with the front left.
01:31 We can now repeat this same process on the front right to increase the camber and then drop the front of the car back down onto the ground and settle it.
01:39 The rear camber adjustment process is simpler, however the car does not need to be jacked up to make the adjustment.
01:45 Which is a time saver.
01:47 After cracking off the top link adjuster lock nut, the adjuster can be turned by hand to adjust the camber.
01:53 With all the camber adjustments made, we can now move around the car and record the new camber values.
01:59 Now measure the new toe settings at all 4 corners, record them and adjust the steering arms as required.
02:05 As you gain more experience, you'll start to anticipate how much you need to compensate the toe for, for a given camber change for your car.
02:12 Once the toe is set to target, recheck the cambers and record them.
02:15 At this point, we're just moving iteratively, repeating the loop of checking and setting camber and toe on both axles until we reach our targets.
