i moved a wooden shed (10x16) onto my property but in the process of removing it from the other locale, i managed to jack the two end walls a bit out of kilter. one is off by about a foot and the other only  a few inches. i heard of a technique whereby one can retweak the walls by fastening  a board and vibrating it but have no clue how one would  go about  doing that. if anyone  has specifics on that technique i would really appreciate any help i can get as it is rather a nice shed and will be  my new workshop. thank you all in advance.   and no  i did  not intentionally post this in read first  forum . it didnt accept  it here at  first so i refreshed and apparently it  brought up the  read first forum instead of this one and now it wont let me remove the inadvertent post from read first forum , sorry all.

Two opposing walls are out of plumb, but the two other walls aren't? Where are you off at? I'm having some problems figuring out how you managed to get opposing walls out of plumb/square without effecting the adjacent walls.

My advice would be to plumb and square each end then reinforce them using 2X4's. I've never vibrated anything with the exception of sinking cement in post holes. Of the small structures I've had to resquar/plumb, I used a pulley to get the tension to align what/where I needed.

Like Craig, I'm having a little trouble figuring out how one wall can be out more than the other, if it was square before the move. I would suggest getting someone with a winch to pull the one end back into square ( I suspect you are talking about the footprint being off) and then recheck all corners using the 3/4/5 method.

If it is out of square, put eyebolts through each corner on the diagonal. Get two fence stretcher type cable winches (Power-Pull) and tighten eah until diagonals measure same.

If wall is pulled away from flooring joists then you need another method.

Probably run the cable under each side of building and attach each end to landscape timber or equivalent and winch and then hammer until the walls are back in alignment.

Pictures would really help.
