    dropping t-case is more for the front angle

    The front angle is a lot steeper than the rear.

    Sorry I was not very clear on that.

    I meant to say do you need to lower the t-case if you are using a cv rear driveshaft?

    Thanks

    most times no you wont need to drop the t-case if using a CV rear driveshaft. just want to make sure you have your pinion pointed a couple degrees down from the t-case and take good measurements for driveshaft length.

    How is lowering the case (assuming a married case) going to help the front when it makes the angle at the front shaft steeper?

    It depends on how much lift you have. Give us some info & we can help. Generally slip yokes need to be opperated at less angle than fixed. The best answer is to drive it and see if you need it. No reason to give back clerance you just put on.

    Make pinion point down a degree or so to makeup for axlewrap--so i hear.

    Lowering Tcase actaully makes front driveline at a worse angle but its ok, cause the front shaft is a constant velocity (cv) from the factory.

    You may or may not have to drop tcase, depending on how much lift you are getting and how long of a driveshaft? I have about 7" of lift and i have the tcase dropped a bit and a cv shaft and i have absolutely no driveline vibe/noise.
