Latest update on the wheel hub madness...
I wound up disconnecting the CV axle and removing the entire assembly with the steering knuckle attached, then took it to Cal Poly's machining shop to drill out these stubborn bolts. Two of the bolts just came off after using a breaker bar, and the two others had to be drilled out.
After those four bolts were removed, we had to use a pulley puller to separate the knuckle from the hub as it was disconnected from the truck. With some finesse, we got the two separated and were able to knock out the studs using a hydraulic press. After the studs were removed, the hub was able to be easily removed from the rotor and then it was time to order some Domino's
The fun part was putting the new hub on. We tried putting the studs back in with a punch and hammer, but it was incredibly loud and just wasn't working out. We got creative with the hydraulic press, and were able to support the rotor with metal blocks on the rails of the press. One by one, we got all eight studs seated after applying 2500 PSI which we thought was pretty insane! Now that the job is done, all that I need to do is put in the new seal on the knuckle, replace the ABS sensor since it was contaminated with grease from the bearings (explains why my ABS light was on), and finish the night off with a cold beer
Out of curiosity for those seasoned with changing rotors on the K2500: Is there a tool out there to put in these wheel studs? I would like to do my own brake jobs, but I don't always have access to a hydraulic press. With that being said, 2500 PSI is an incredible amount of force and I feel like using a punch and a hammer wouldn't yield good results and take forever to do
