I just finished replacing the stock 3.23 rear on my OCC with a 3.42. I built the axle with Moser axles, Truetrac differential, and premium Richmond gears. It runs quiet, and makes the tires spin a little more than the 3.23. I must put a 2 tooth larger driven gear on the VSS to calm down the speedo. I need to write down the mileage for the break-in oil change. Pinion shim is 0.038", and I have .010" lash. This is my first rear rebuild, and all the mystery is BS.
I also replaced the steering intermediate shaft with a home made unit using a couple of inexpensive stainless universals I found on ebay (look exactly like the Borgeson units), and a couple of OEM shafts dissected, and reassembled to fit. It managed to slip a couple of splines while installing, but that is easy to fix. It really cleaned up my engine compartment by removing a lot of heat shielding on the heat vulnerable rubber parts of the OEM unit.
The silver tape on the center of the shaft is to protect the plastic seal between the two segments of the D tube. It is near a header pipe, and it gets pretty hot there. The lower shaft has a pin on the end, and that is as far as the splined end would go on. The pin hits the X if I try to insert it any further. I may cut the pin off in the future.
thats pretty sweet fred! i had to replace that steeering shaft on one of my olds trucks. the failure mode was the ujoints start to freeze up (new england corrosion) when that happens the steering gets oddly notchy !!!when i took the old part out i couldnt even move one of the joints by hand
You are just scratching the surface with the modifications and upgrades on that car Fred. You should post your progress here more often. I still haven’t seen your repairs since the run in with a dump truck.
