Yesterday I took a short trip in the coach and noticed the steering was more precise and reactive than previously. Therefore I suspect that the improvement in steering performance with the addition of Gunk PSF was due to the "conditioners" not the higher viscosity. Otherwise there is little to explain the improvement over time with no other changes being made recently. If this is true, it would suggest that the internal seals on the steering gear are not sealing well due to age and I'm due for a new gear sometime in the not real distant future when the "conditioners" no longer are effective in helping the seals swell up. An overhauled gear is about $750 plus labor (if I don't do it myself) so it's not a hugh expense.
