    About a year ago I bought my first blazer and the front driveshaft was not connected but I have it and now that I have gotten into 4 wheeling I want to hook it up but I dont know if it is safe to, what are some things to check?and how would you check such things as splines, u-joints, etc.?
    Thanks

    Install it, grab onto the tube, and check for movement by shaking it. If it doesn't move, assume it is fine, and go about your wheeling.

    Bolts are 7/16-14" by 1-1.25" long grade 8s with lock washers.

    Straps you can get from your local auto parts store.

    Yes the straps come with the bolts. The bolts are 5/16-24 but have 7/16" heads instead of the normal 1/2" heads for 5/16" bolts.

    Yes you can get them at Napa. Any place that carries u joints will probably have them.

    That is a 1310 joint at your pinion.
