    Default Understanding axle ratios

    I'm looking at a dana 44 front end to put on my '89 suburban 1/2 ton. I am probably going with the 44 due to cost issues.
    The axle I'm looking at looks nice... good joints, straight, tight, OK brakes... nice and quiet... exactly what I'm looking for except it's the wrong gear ratio. it's a 3.07 (so the guy says) and I have a 3.42.
    Would I be better to put 3.42's in the 44 or 3.07 in my rear?....
    What is the best overall ratio for decent highway driving with some medium to light-heavy towing? If I have to change both I will. I just want something I can count on.

    Also.... do the ring/pinions exchange between these axles? in other words can I put my 3.42 gears out of my 10 bolt in the dana 44?
