My front 10 bolt spit out it's center section last week so I went to the junkyard to find a replacement. In looking for a front ten bolt I stumbled upon numerous 14 bolts rears under vans and trucks. I also found an 8 lug front end under a 3/4 ton truck. I guessing the front end is a 44 or ten bolt. Needless to say, I would rather spend my money on something stronger than my junk front and 12 bolt rear. I have a few questions of what to look for. Any help would be greatly appreciated. 1. What is the easiest way to check the gear ratios on these things? 2. I am assuming I would want a 14 bolt with the center hub that sticks out between the lug nuts. Does this mean it is a FF? 3. Would it be best to get a 14 bolt with an open carrier? 4. Will the lockouts on my 1/2 ton 10 bolt fit the 3/4 ton axle? 5. Are the axleshafts the same on the two front ends? That should do it for now. I want to pull these things this weekend. Oh yeah, I can get both axles for about $400.
