The Stovebolt Site Forums The Parking Lot Big Bolts Axles

Does anyone know why the axles would have had different splines in a 46, 1.5 ton? I got a different rear end for my truck, and all the numbers matched on the ring gear,pinion,etc. Come to find out these spider gears have 10 splines, and my axles have 16 splines. Bottom line I need a set of axles for this rear end.I know what your gonna say! I scrapped the old one. Any help would be appreciated.

Thanks

Kevin

Hy mo2cyl, what is the "new" diff. out of, could it be from a non GM product? Did you install it into a 46 GM housing? You may actually be looking for some spider gears.

Read this thread. Might help explain a few things, https://www.stovebolt.com/ubbthreads/ubbthreads.php/ubb/showflat/Number/396126/fpart/1

Thanks for the response. Yes both differentials were the exact same, including the numbers on the spider gears. I made a road trip today down south into Oklahoma where there are quite a few 1.5 ton trucks for parts. I did find what I was needing, but we pulled axles out of 4 different ton and half chevy rear ends to find a set with 10 splines. Thanks to Tom's truck parts in Miami Oklahoma. Tom said as long as he has been in the parts business he did not no why there was a difference. All of his rear ends looked exactly the same, but one had the 10 splines instead of 16. Im good to go!
Thanks Kevin

Thank you also Spanky. All of those rear ends were single speed just like mine. Probably used different manufactures for the internal gears.
