    I currently have an 83 blazer w/ a 10 bolt front diff, the rear has a 3/4 ton 8 lug. I was wondering if I should stay with my 10 bolt and just change the shafts, hubs, etc... to make it 8 lug in the front like the rear or should I get a 3/4 ton front differential from a 1990 suburban for 150. that my friend has which is in good condition and matches the rear gears. The 3/4 ton is already 8 lug so I would just bolt this one on. What do you guys think, let me know. Is the 3/4 diff. better than the 10 bolt. What should I do? Any help would be greatly appreciated. Thanks.

    Both are 10 bolts. Neither is really any better than the other, other than that the 90 one is newer and has 30 spline axles instead of 28.

    I personally would do whatever it takes to make sure the axle you're getting has the correct gear ratio. That would most likely mean getting the 3/4 ton axle complete in your case. $150 for that axle is a pretty decent deal, IF it has the gears you want.

    To change your current axle to 8 lug you don't need shafts or lockout hubs or even brake calipers. Just caliper backing platess and hub/rotor assemblies.

    If you dont want to deal with anything then I would bolt in the 90 axle. Just hang your calipers with sturdy wire , drop out old axle slide in new one. Your calipers will fit both axles and you wouldn't have to bleed brakes, or worry about taking the rotors etc from one to the other. /forums/images/graemlins/k5.gif

    Yup, just be sure the new front axle's gearing and the rear axle's gearing match.
