10 Bolt rear end axle length - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anthony14 · 08-13-2019, 02:56 PM

Hi guys, I have a 8.5" 10 bolt in my truck. The axles are worn where the stock bearing rides and I installed some axle saver bearings from Centric (41464000E). These are "economy" axle saver bearings. Sure as $hit they were leaking in no time. My question is do I replace them with some SKF axle savers - would it make a difference? Or do I get new axles? Can I tell what length axles I need without pulling them? (I don't have them out, the picture is from when I last had them out.) Last time I had them out I'm pretty sure they were 28 spline. I attached a pic with external dimensions.

If you don't know anything about what the axle came out of I'd either guess at an '80s year (I think all are the same) or pull the shafts to measure. I know there were different brakes with varying backing plates. But that's probably to make all work with same shafts

Yeah I pulled them out. Found the seal all messed up, I dont think I did it pulling it out, but based on the putting even if the seal was good I'm not sure it would seal.
