I just borrowed this from my neighbor. What a beast.
Ran that pinion nut snug with ease.
Ill check out the video, but I actually was leaning toward battery. I really just want something that works like it should.
Before I go to Harbor Freight, I may look to see if dewalt makes one that takes the 20v batteries I already have. So many of them come as “tool only”, so that might make sense. I’ll price them out, but with the suspension work ahead of me, one of these will make it much more enjoyable!
