I was going to post this in my SAS buildup thread, but figured a separate thread may be of use to others.
I had 4.56 gears and an ARB installed by a shop because it was a bit too cold to deal with it since this thing doesn't fit into anybody's garage.
Long story short- the rear broke up and I'm in the process of rebuilding it.
On to the pics-
First the carnage:
Now onto the rebuild, and this is going to take me a coupla days since I'm doing it in a makeshift tarp garage...in da freeezzin cold!
The tool to pull the axle tube bearings...
The size needed for the Ford 8.8, since you can buy one and not the set, it screws on to a slaphammer.
Bearings and seals removed:
Cleaned tube, I had to run it through a couple of times with new rags after spraying the hell out of it with Carb and Choke cleaner to get all the metal particles out of it. Once I was happy with how clean it was I doused a couple of rags with gear oil and ran those through the tubes to pull any remaining particles (clean oiled rag each time), since the gear oil is higher viscosity than the cleaner was I switched rags so each rag pulled whatever was left behind, when it was completely cleared I started setting up for measurements.
The pinion depth tool, about $143 US from Tavia Performance Tools
Attach the tool to one of the bearing cap bolt holes:
This is done to check what the "offset" (sometimes there is, sometimes there isn't) from center of the carrier is. You have to measure the race for outside diameter and then do the math to determine (if there is an) offset. If the carrier bearing bore is not exactly halfed then there is an offset, whether it needs to be added or subtraced is determined by whether the "offset" is greater than or less than half of the race diameter. The addition or subtraction takes place when you take an actual pinion depth measurement.
The tool is run across the deepest point of the bore to obtain measurements...run it back and forth a few times to find the deepest point.
The measurement for outside diameter that I came up with for the race is 3.062 so- 3.062/2=1.531 (I'll double/triple check it tomorrow) which puts you at the exact center of the carrier bearings. That's the point the pinion depth is measured from. I'll determine the offset tomorrow.
That's it so far, more tomorrow.
