[You must be registered and logged in to see this image.]Ok. Start Remove the upper caliper bolt. 14mm
[You must be registered and logged in to see this image.]Then the lower caliper bolt 14mm.
[You must be registered and logged in to see this image.]Then remove the Rotor. If stuck hit it with a mallet.
[You must be registered and logged in to see this image.]Next remove the cotter pin.
[You must be registered and logged in to see this image.]Get the impact gun and remove the axle nut using a 36mm socket.
[You must be registered and logged in to see this image.]hit the nut with a mallet to loosen the axle, we will slide it out later.
[You must be registered and logged in to see this image.]Moving to the lower strut bolt using a 17mm.
[You must be registered and logged in to see this image.]Use something to pry it out. if you don't want to scratch your coils put a rag in between.
[You must be registered and logged in to see this image.]The toe link 19mm.
[You must be registered and logged in to see this image.]The camber link 17mm one side 19mm other side.
[You must be registered and logged in to see this image.]Traction link 19mm
[You must be registered and logged in to see this image.]Now with the knuckle loose and hanging only from the lower ball joint. push in on the axle and pull out on the knuckle and slide it out.
[You must be registered and logged in to see this image.]and its out.
[You must be registered and logged in to see this image.]These 4 bolt hold the hub in place.
[You must be registered and logged in to see this image.]Remove them using the impact gun and 19mm short socket.
[You must be registered and logged in to see this image.]loose them 3/4 of the way to keep the hub from falling.
[You must be registered and logged in to see this image.]Use the 36mm socket and place it over the center and hit it.
[You must be registered and logged in to see this image.]After a few good hits it should pop out.
[You must be registered and logged in to see this image.]Install the all the link back to hold the knuckle while you work on it.
[You must be registered and logged in to see this image.]Mark your cuts with a sharpie.
[You must be registered and logged in to see this image.]Make sure you wear the necessary PPE. ( gloves, mask. breather filter. goggles. etc..)
[You must be registered and logged in to see this image.]It should look something like this.
[You must be registered and logged in to see this image.]Time to get the first bracket and 4 bolt and locking washers that were included on the GM kit.
[You must be registered and logged in to see this image.]I used the wheel lug nuts to hold the bracket in place. check if both calipers will clear.
[You must be registered and logged in to see this image.]First Challenge is to shave the knuckle in order for the lower caliper bolt to slide in place.
[You must be registered and logged in to see this image.]I move the bracket lil forward to see how much material to shave off.
[You must be registered and logged in to see this image.]Another issue was that the back of the caliper was hitting the knuckle and preventing it from aligning with the bolts.
[You must be registered and logged in to see this image.]After a few tryouts now everything clears.. I choose to shave the knuckle and not the caliper because shaving the caliper will void
The part warranty.
[You must be registered and logged in to see this image.]Get the bracket and the hub ready.
[You must be registered and logged in to see this image.]insert the new hub bolt and use them as a guides.
[You must be registered and logged in to see this image.]looking nasty.
[You must be registered and logged in to see this image.]good.
[You must be registered and logged in to see this image.]final checks.
[You must be registered and logged in to see this image.]See how the bracket replaces the stock mounting ears.
[You must be registered and logged in to see this image.]Time to bolt everything up and torque to factory specs. ( That ball joint looks nasty.)
[You must be registered and logged in to see this image.]all set.
[You must be registered and logged in to see this image.]After installing the axle and turning the disc. the bolts from the hub were rubbing against the axle.
2 ways to fix this. align the flat part of the head bolt to the axle. or shave.
[You must be registered and logged in to see this image.]Minor shaving.
[You must be registered and logged in to see this image.]Before installing the Rotor make sure you put the gap ring.
[You must be registered and logged in to see this image.]and there it is everything installed and torqued to factory specs. I notice that the rotor doesn't center perfectly with the caliper.
it shouldn't be a problem.
[You must be registered and logged in to see this image.]Good Clearance.
[You must be registered and logged in to see this image.]Give the disc some turns. and check for rubbing.
[You must be registered and logged in to see this image.]cant wait.
[You must be registered and logged in to see this image.]wheel on.
[You must be registered and logged in to see this image.]Looking good.
[You must be registered and logged in to see this image.]Now continue with the other side.
Next up will be the Parts shop max hydro e brake bolt on setup. and the Plumbing.
Hope this helps.
