Driveshaft "thud" after TSB leaf spring change

    Hello everyone! i recently installed a pair of TSB leaf springs to my 07 Tacoma. Immediately following the change, i am feeling a THUD in the driveshaft mostly when taking my foot off the brake, but also acceleration from complete stop.
    I am pretty sure it is the yoke binding. However, a few months ago, i had my driveshaft rebuilt, re-balanced, and phased by a reputable shop. I am fairly confident "just greasing the yoke" wouldn't fix the problem.
    The TSB springs added a leaf the the rear, so im thinking the driveshaft angle just changed enough to start causing binding issues.
    I do have 6112's up front on the 2nd location just to even out the truck.

    Has anyone had this problem after they got their new springs installed?
    Is there some sort of alignment washers i need due to the extra spring?
    Could i have moved the rear diff out of alignment during the install process? i did do one spring set at a time, but i am only a backyard hero when it comes to being a mechanic.
    Thanks for looking at my post!

    I had a very similar problem, but don't believe it had to do with changing my leaf springs. I greased the slip yoke heavily and solved the issue. 35k miles and all is good.
