Bob, I appreciate the concern on using the NEO on the steering rack and the wheel bearings. One reason I said this would be a test for the product, I am also concerned that it may not work. But, I used it on the "O" rings on my motorhome holding tanks manifold because it is supposed to be non washable, and non melting. Previously I would use commercial grade "Vaseline" on "O" rings and it would melt away on relatively warm temps, so I tried Neo and it works great in that application. On the steering rack, I can turn the input coupling by hand, although not real easily, and the wheel hubs are kinda stiff also. The reason I used this grade NEO is because it is used primarily on boat trailers and off-road vehicles, which, arbitrarily, do get abusive use. I hadn't planned on using this until after I read the label on the container. If all the uses and advantages are true or close to it, I should be o.k., if not cleaning and a different lubricant will be an easy change out. I don't dispute what you experienced with it is true, and I don't know if you were in a racing or DD environment. But I will find out soon, I hope. And again, thanx for the input, your expertise is always appreciated.
