Re: Steering Box Leak Just Started Reply #25 – March 16, 2020, 12:14:54 pm Quote from: Chuck Pearson – March 16, 2020, 11:54:45 amMy decision to add this stuff was based on positive past experiences. I've been running it in my coach for close to 10 years now and unless my leaking fan motors cured themselves, it is still working well. That said, I'm comfortable with experimentation, and given the above research, I'm withdrawing my recommendation. I will, personally, continue to use it without reservation. YMMV as they say.....I've also been using it in my hydraulic system for several years. It slowed the leak on my hydraulic pump until I finally had the shaft seal replaced. Unless someone wants to suggest that it caused my steering box seal to leak, I would say that it has done no harm. It may have delayed the steering box leak, and it may have prevented other leaks that I'll never know about. I wouldn't hesitate to use it. Quote Selected 1 Likes
