I've had a locker in my 71 Mustang with a 460 and a Richmond 5speed for a few years but never really drove it much on the street. Lately I've taken it out on the street more than usual and I'm reminded of how it seems to pull slightly to one side when I hit the gas and when I let off I feel it pull to the other side. I've owned this car for you years and I've had all kinds of diffs in it, from open, to traction lok, spool, etc.but do lockers normally do this?
