Nitrousn I forgot about the knuckles.One I had I had to hunt 20 yards to find used knuckles and that was in the 80s.Once they really start to wear the wheel gets tons of sloop and wants to lean.That and the grinding.I bought one RamCharger real cheap because of the knuckle hub wear.Took me about a month to fix it because I had to find parts cheap.You used to be able to buy a complete hub.They were pricey even back then.Rocky
