DING DING DING I think i found my problem tell me if I'm crazy. I have a 10.5" Sterling rear. When ordering gears I was told to get the 10.25" gears due to the longer pinion splines that was stronger. which when ordering said gears they actually only offer the 10.25 because they are cheaper in price. Here lies the problem. the 10.25" gears do not fit the 10.5" carrier that is currently in the truck? it is slightly thicker and does not allow for the ring and pinion to align correctly?
" If you're short on cash during a rebuild (depending on the ratio you want to use, factory parts for the 10.50-inch Sterling can be almost double the cost of 10.25-inch aftermarket parts), you can use the 2nd-generation 10.25-inch case/carrier and gearset in the 10.50-inch housing (as mentioned above). "
"To address the bearing and race issue, you can use the ring-and-pinion from the 2nd-generation 10.25-inch. "

Actually i dont think it does now.
"You can use 10.25 gears in a 10.5 if you use 10.25 pinion bearings, so, I'd assume that 10.5 gears could be put into a 10.25 if you use 10.5 pinion bearings also. Carriers are interchangable."

That almost doesn't make sense. You would have to have the carrier for a 10.5 for the gear set for a 10.5 to work. I think what he described means that you can swap 10.5 and 10.25 gears and carriers provided that you use the correct bearing for the size needed.
My understanding is you have 10.25 and are trying to put 10.5 into it, it would seem that it needs the 10.5 carrier to work properly.
Call over to weller truck parts or Valley truck parts and ask them?

You can use the late ninetys 10.25 gear set and carrier to put into your truck. The carriers themselves are interchangeable between the 10.25 and 10.5 but require the gears for said carrier for which they were designed. In your case I would break down and buy the 10.5 gears due the ratio you need to run. The downside to high numerical gears is there is so few teeth left on the pinion gear, which weakens it.

Ya i have a 10.5" and all the gears you can buy aftermarket usually come in 10.25" the carriers are the same acording to all the parts shops i can find.
10.25" & 10.5" Full Float Detroit Locker
"Ring gear size and inner pinion bearing size are the differences between the 10.5" and 10.25"
The inner pinion bearing is taller to make up for the 0.25" difference in ring gear diameter. Other than that, the housing is the same as are the rest of the internals."
