Axle swap gone horribley wrong........

[Rouphis]

So I go to the Pick and Pull, hunting for a 4.10 to swap into my 3.45 truck. Three junkyards later, I find ONE truck that is something besides a 3.45 or a 3.08. Its a 98 B3000 w/ a 7.5 3.73. I figure its better than what I have now. So I pull it, take it home, replace the bearings and swap the backing plates for the ones on my truck.

Here is where I find issue #1. I go to hook up the brake line, and discover that the fitting is smaller that my wheel cylinders. OK no huge deal. Swap the hard line from my old axle, a little bending to make up for the extra length and all is well.

I put the axle shafts back in. then try to reinstall the drum, and discover that the hub on the new axle is quite a bit larger than the one currently on my truck.

Will two 93-97 axle shafts fit in the 98 axle? If not what is plan B?

Thanks

Yes, the shafts will fit.

that is strange. you mean the bolt pattern is bigger??

No, the hub center that the brake drum fits over is larger.

Why the brake swap? I'm thinking that's where it started.
