Ok guys. This job isn’t as hard as people make it out to be if you know what you’re doing.. I didn’t, and the first one took me about 6 hours but the second one only 3. I followed some instructions on here but found they could have been better…. The biggest thing is you don’t have to pull the steering knuckle or separate anything on the bench.. Nor did I screw up the ABS sensor but I think I might know why some do….
1. Jack up the truck and place the front on jack stands. You will be turning the wheel back and forth and if one wheel is touching the ground it will walk right off a jack. Place the stands on the frame so the suspension is fully extended.. This will give you more room to work and also extend the 4x4 axle if equipped making your job much easier.
2. Take off wheels by removing the lug nuts
3. Place a pry bar in the lug bolts (as a brace) and loosen the 6 bolts in the face of the spindle that hold the rotor to the spindle. (see pic below)
4. Leave the bar in place and remove the Axle nut and Washer.
5. Remove the pry bar.
6. Crank the truck and turn the front of the rotor outward (Steering wheel left if working on the driver’s side, right if working on the Passenger side.)
7. Reach behind the steering knuckle and remove 2 bolts holding the hub to the knuckle. (4 bolts hold the hub to the knuckle. In this step you remove 2 on this side, later in step 11 you remove the other 2)
8. Crank the truck and turn the front of the rotor inward. (Steering wheel right if working on the drivers side, Left if working on the Passenger side.)
9. Unbolt the caliper and hang up out of the way.
10. Remove the bake mounting bracket by the 2 bolts behind the steering knuckle.
11. Remove the remaining 2 bolts from behind the knuckle that bolts into the Hub.
12. Find the wire for the ABS sensor and trace it. The first clip will be a metal bracket on the frame, using a screwdriver open the two metal clips leaving the bracket on the truck. Keep following the wire and removing the plastic clips. (I simply pried them from the frame being careful not to break them leaving them on the wire)
13. Mounted behind the fender is the disconnect clip for the ABS wire. The clip is mounted to the metal via 2 clips right behind the fender well. Disconnect it. (I removed the top piece of the plastic dirt shield for easier access.)
14. Take a 18 inch piece of 2x4 and place it behind the rear edge of the rotor with the wheel inward. And the other end against the dimple hole in the square frame (See Pic 1 below The Red line is 2x4. Obviously the caliper and bracket in the pic would be removed by this point)
15. With the 2x4 in place have someone turn the wheel until it tightens up against the 2x4. Turn a little harder. The hub will pop loose of the steering knuckle. It will sound like you broke something when it pops loose.
16. Take the same block of wood and place the end against the very end of the 4x4 axle. Tap it a few times with a medium hammer until you can see the axle is movable inward. (It will spring back out you were just making sure it’s movable and isn’t stuck in the hub.)
17. Once the next step is complete and the hub free you will need to hold onto the hub and feed the ABS wire through the steering knuckle. If you go to set that hub down you will break that wire. (See pic 2 below.)
18. Place a small block of wood against the end of the 4x4 axle and put your knee on it. Place both hands on the rotor… PUSH HARD with your knee and you should see the 4x4 shaft move inward…. Pull on the rotor in an outward and Upward motion. Wiggle.. Wiggle.. Pull.. Pull.. Cuss…
19. Work on getting the ABS wire and clips through the Steering knuckle.
20. Once the entire infernal contraption is in your lap unbolt the 6 bolts through the spindle holding on the rotor. Remove said rotor, spit on it and throw it across the shop.
21. IMPORTANT…. This is where I’m pretty sure people are reporting bad sensors, they fail to do this step. On the back of the hub is a metal ring with a wire attached to it. This is the ABS Sensor. You will notice you probably pulled it away some while removing the hub. The gap between the sensor and the magneto should be less than the thickness of a credit card. No problem. Place a flat piece of wood across it (not the wire though) and lightly tap it back into place. Take a q-tip or 10 and clean all around inside this ring.
22. Take a wire brush and clean the ring on the hub and inside the steering knuckle it will make installation much easier. (See pic 3 Red marks.)
23. Install new rotor.. CORRECTLY.. It will go on backwards and unless you want to reinstall everything all the way to the caliper before you realize you screwed up. Check it now..
24. Spray some good old WD-40 on the hole in the steering knuckle and the end of the 4x4 drive shaft.
25. Reinstall the hub. Being careful to fish the ABS wire back through the hole. NOTE the dirt shield goes towards the front of the vehicle. Not the rear. That caliper goes there silly…. LOL..
26. Installation is reverse of removal. For the rest of the parts.
