Well, the 10.25 is finally under my truck. Existing u bolts worked but my god were they rusted on there! I've been soaking everything in pb blaster for nearly 2 weeks now. Probably spent 3 hours taking the nuts off the u bolts. Put a nice bend in my Pittsburg 24" breaker bar and toasted a craftsman ratchet. No wonder my dewalt cordless impact wouldn't budge them. Did manage to shear one of the u bolts right off at the nut though lol! That's the only thing stopping me from driving the truck. Need a dam nut to go on the u bolt I had laying around.... also, turns out the 94 f350 I got the axle out of had a 1330 ford big cap u joint yoke, not a 1350. Ordered a conversion joint for no reason lol. I placed an order for a diff temp gauge last night to keep an eye on the new bearings and gears. I'm pretty sure I'm going to have to have my drive shaft shortened. The new pinion is slightly longer and at full droop, it doesn't look like the the splines on the slip yoke have much room to compress. I'm going to be calling drive line shops in the morning. Can't wait to see how the truck drives going to 3.73s from 3.07s, especially after the break in period
. Do you guys have a preferred method to gear break in over the 500 easy miles then change the oil? Should I do a towing break in?
