Went into the city for dinner with the trouble-and-strife tonight and noticed something strange when turning corners. This only seems to happen at low speeds. The best way I can describe it is that it feels like the car is driving over bumps in the road, or expansion joints in concrete when turning at low speed. Seems worse at closer to full lock. If anyone has been in a RWD car with a welded or locker diff, it feels like when the inside wheel 'shuffles' during slow cornering. At first I though it was a flat, but all tyre pressures were fine. Checked PS fluid, as the car recently had a major service and that was fine too (if anything a little high above the MAX HOT line (car was hot) ).
