I'm waiting (impatiently) on parts for my motorized rollerskate... As I suspected I have a badly worn inner tie-rod end. Hopefully this week I will have them available and installed. Not work I intend to do. I did enough pounding on plumbing today (with no result) Pipes are age welded together.... so I have to consider another strategy... no room under house to really wrench on them and I can't find my large monkey wrench (not a pipe wrench, but a knock off 'crescent' wrench) older (hopefully galvanized steel) pipes put together with knuckles (trying to avoid busting my knuckles while getting the ones in the pipe to come loose....) PEX going in when I get things apart!
