I had the puling left issue in my GU. The left side off camber on the roads don't help at all.
I took it to a mob called Pro Axle, a very reputable front end allignment company. They first made sure everything else was good. In the end the only fix for mine was a return to centre steering damper. *puts on flame proof suit*. Many say they are shit and just a bandaid to fix the issue but none can say what the actual fix is. Pro Axle said theres nothing wrong with them, I can't either, I've now had one for probably three years. The only small issue is your steering will be slightly heavier, but after an hour of driving you wont even know the difference.
