exactly .... i have a jig made just for this. you chain the rear down over the rims and roll it over 1 time . we use a jack to re-square them. rims must be true..... i used this on circle track rears for years. we got bumped all the time and it was the fastest sure fire way to check and repair them all at 1 time.... sliding the axels out will let you know if its bad enough too ..
