I need to change the leaf spring bushing on the back of my 26' class c motorhome, I can't find jackstands I can afford to support the rear while I work on it. I did some searching and surprisingly didn't find anything to help.
I was thinking of using a 4" square tube, .25 wall, and 3.5" .25 square tube as a nested pair. 10"x10" .25 plate for the bottom, center the 4" and weld it on the plate. Then add .25" triangle gussets to each corner. Add a 3/4 pin to hold it up. Frame height to ground is 16". I was thinking the 4" tube would be 14" tall and the 3.5 would be 15" tall. This would give me a range of 15" to around 22", still need some overlap to provide strength and stability.
Considering 2 pins, one on each side. I could space the holes 1" apart, offset 1/2 on the other side. This would give me 1/2" lift increments but keep material for strength on each side for load.
Does this sound safe? Im guessing the back should be upwards of 3.5 tons.
Will 4" and 3.5" slide like I think it will?
Is a 3/4 pin large enough or should I go to 1"?
