What are the chances that the original 3.08 gears in my front diff could completely rip apart my rear 3.42 diff? It dawned on me last night that while I have 3.42s in the back, I'm willing to bet I still have a 3.08 up front. This would explain why I tore out my rear end the first day I owned the truck, and it would explain why my auto lockouts are completely ripped apart. So, what are the chances that my slower turning front diff on dry pavement would be strong enough to alter the speed of the transfer case enough that it would spin off the driveshaft nut in the diff, causing it to jump a tooth in the rear end, and subsequently rip a 4 inch gouge in the Wheel part of the wheel and pinion?? Or am I on crack and the front diff speed has no bearing on the rear diff, but would explain why my front end is torn apart... My reason for this gear ratio belief is that the guy fixed up this truck to sell it... made it all nice and pretty for the first sucker (me) who came along to sweep it up and get it off his property. I'm pretty sure with the 3.08 original rear end, it would have been super slow, and I would have been turned off by it. But with a simple $180.00 rear gearing swap, it would appeal to the first guy who drive it as long as it wasn't in 4wd... which I took his word on working... Me=Dumbass... but oh well... I'm sunk deep into this money pit now... As soon as I have a chance, I'll pull the covers off and count the splines... I expect I'll be super pissed.... Oh yeah... in the LMC Blazer catalog, there is a locker available for the Dana 44 stock axle, but not for the stock 10 or 12 bolt... is the Dana 44 locker interchangeable with my Corp 10 bolt?
