Well now that I think about it I did swap out my 1 overload leaf spring to the 3 pack overload springs that were on the donor truck so maybe since I got more spring power it won't move as much as before. But I did go ahead and put a zip tie on the end and pushed it up against driveshaft part that moves, so let's see what happens when I get her on the road.
Also a little preventative maintenance so I don't get road salt and dirt and crud in the u bolt axle shackles to fester. Grease don't corrode metal and everything that would try to get in there will just get stuck to outer layer creating a cement like material that can be cleaned off if needed. But main goal to keep other b.s. out and preserve my parts for ever!!! Lol
