    In 1990 the Blazers came with rear ABS. So what do I do when I swap in the 14 boltff? Will or can I still have the ABS?
    Same goes for the front swap, is there a sensor or something I can change over from the 10 bolts??

    You may be out of luck unless you get the axles from a donor vehicle that has ABS. Disconnecting the ABS may not be worth it or more trouble than it is worth. There is a tone ring that should be inside the front hubs and on the axle shaft in the rear that lets the ABS sensor know when lock-up has occured. You can probably order retrofit axles for the rear and you may be able to use the front hubs off you current vehicle (some year models 10 bolts are pretty much the same as a Dana 44 from the knuckle out). Anyone else have any ideas????

    Check with Steve on that one. He had ABS when he swapped in a 14 bolt. Check on the home page and read the articles there but I don't think he had any problem.

    I think that the rear wheel speed sensor is on the driveshaft (or T-case output). If you don't have wires going to the rear axle than you are in the clear. The only other thing that matters is your final drive ratio (gears and tires)

    I have replaced both front and rear axles and driveshafts and had no problems with my ABS. There are no wires running to the either axle.
