    This past Saturday, I blew up the short side inner shaft, Ujoint, and 35 spline stub in my D60. I'm trying to decide whether to replace it with $$$ aftermarket chromoly shafts and possibly a CTM/OX Ujoint or to put the Spicer stuff back in with a new spicer life Ujoint. Who has gone which route and how about suggestions for what to put back in and where to get it. I'm running 44" TSLs with 5.13s and Detroits behinds 350/4spd power.

    There was a thread in this forum about the new moly shafts, and also one in the ORD forum. I think OL14BLAZE started the one in here, don't remember who started the other one.

    Edit: Thread in Garage

    Thread in ORD forum

    Pirate4x4 has a really great tech article out there. Here's the link:

    Here's the info from that link:

    How strong are the different axle shafts? (note these figures are subject to much debate)

    Standard Dana axles (1040 steel, induction hardened)

    30 sp 1.31" 6,044.1 ft/lbs
    35 sp 1.50" 8,966.2 ft/lbs.

    Moser Engineering (1541m, induction hardened)

    30 Spline - 6,200 ft/ lbs.

    35 spline - 9,600 ft/lbs.

    Aftermarket 4340 steel, thru hardened

    30sp 1.31" 9,923.5 ft/lbs
    35 sp 1.5" 14,721 ft/lbs

    The Formula is:
    Yield Torque (in/lb)= Tensile Strength ( psi) x polar moment of inertia/ radius of material
