Installed 2" blocks - "bump" when taking off
Over the weekend I installed some 2" lift blocks on my '98 Ranger. I already have Chevy Shackles and Explorer leafs. I have the shackles on the lower setting. Since installing the blocks, I am getting a bump when taking off. If I roll off very slow, it is not felt until I accelerate hard. Seems to me that it might be the famous slip yoke problem? Is there anyway to find out for sure? How do I go about greasing the yoke?
Also, where can I get a set of new u-bolts?
