Front Suspension rebuild

To Charger;Yes, over the years, there have been many different companies selling suspension parts. Some of the aftermarket stuff is pure crap. There have been various sized ball-sockets out there. The smallest Ive seen for the 67 to 72 A-bodys are the oem Mopar stuff circa the 60s and 70s. The Moogs and old TRWs are/were pretty tight too. The off brand has considerable variation.I found running a 15 inch front wheel on my 68 almost got the wheel off the BJ. I wee bit of grinding on a socket-flat fixed er up. That 15 incher was a Wheel Vintiques custom Rallaye wheel, 5X4, and custom backspace. Used em one summer with sticky rubber. The tires were real soft and it didnt take long to trash em. Not 8 weeks. Sure was fun while it lasted.
-Wait, I just reread your post. Im not getting it. How is it possible for the tire to rub on a bj, when turning and not when straight? The relationship between the two is fixed in space. Or is the tire rubbing on a tierod. If yes, thats indicative of a different problem.
-Could be; broken/missing/hammered stop on the LCA or LBJ, bent steering arm,or mismatched wheel backspaces. You might want to look into those before you replace the bj, unless, of course the bj needs replacing anyway.
