The 9" is in place, but that’s about it. I spent most of the Sat. before Easter chasing down parts and grinding the axle shaft flanges so that the new rotors would fit. It started out by me not wanting to use redrilled Chevy rotors. So I decided to go with 95 Dodge ram rotors because of the bolt pattern and the bigger diameter "hat" to fit over the axle flange. Well apparently there are different size 9" axle shaft flanges, and it needed more than a 1/16" ground down like people say, but that’s no big deal.
Some people say that they put the rear axle on stands, pull the tires, put 'er in drive and run the grinder till the rotor fits. Well I didn't have that option and my hand got tired from turning the axle so I came up wit this idea. It did the job
So while the bench grinder had the axle spinning, I used my Dewalt to grind down the axle flange. Don't worry I didn't grind down too much and weaken it, I compared it to one of my spare shafts and there is still more metal on this one than there is on my spare, so I guess they just used different diameter flanges.
Now the rotor fit over the flange like this.
As it sat at the end of the day.
Well I came back to PA the next weekend to work on it and when I tried to put on my new calipers, the rotor was too thick to fit between the caliper and the new pads. So needless to say I was kind of pissed that I spent all the time grinding down the flanges and now my rotors didn't work. I know other people used these rotors, but apparently they used different calipers than I did. Since I had to use these Cadillac calipers, I had to search for a rotor that was thinner. I ended up with a Zuki Sidekick front rotor. It fit over the flange and def had enough room to fit in the caliper. Actually the new rotor is only about 1/2" thick or so. I saw that other people on pirate used these too, so I think the caliper should have enough movement in the piston to still work.
No pics of the current setup. As it sits right now it’s bolted under the truck with the calipers mounted and sitting under its own weight on jack stands. I still have to bend some new hard lines but besides that it’s all done. Well I still needa find someone to regear the 9". Anyone in PA or MD wanna help me out?
Stay tuned, I'm going to have to turn it on here soon if I'm gonna get it done before Carlisle and the 'Nor Easter. If I can ever stop traveling for work I think I'll be able to make it.
