if you are taking the rear axle u bolts off for relocation and possibly also replacing/bleeding the brakes due to line replacement and doing a wheel bearing dissassemble and check plus welding the spring pad back on at the crack then why not just take the whole axle out from under the truck, take the wheel bearing hubs off and check the housing for straight before you spend money on something that is bent. if bent you can look for another axle from the same style of truck or upgrade to a newer axle with better gearing for you. there may be some wheel fitment issues with a newer axle, I mean the rear axle may have different wheels than the front, but in the end you have spent money on an upgrade instead of on a stop gap and you would get better gearing. if the stock axle is bent then it would require the axle to be straightened at a machine shop which will cost you cash and they may want it totally dissassembled and cleaned before they put it on their equipement.
just a thought
