I decided to drill and lubricate my column tonight. I turned the wheel from lock to lock a few times to work the Wurth HHS 2000 around but even on a cool day it still felt a bit sticky. I decided to investigate further.
With the car on axle stands it was easier to feel what the steering was doing. I decided to play with the eccentric adjustor again while the wheels were off the ground. This way, the relationship between the adjustor and the steering feel was very clear. I was able to feel the following:
- Drag on the column increasing to a horrible notchy point by adjusting bottom of the ring towards the rear of the car.
- Drag on the column decreasing to a light-as-a-feather (but with increasing amounts of slop) point by adjusting the bottom of the ring towards the front of the car.
I decided to make it more scientific than guess work, with a view to being able to carry out this adjustment repeatably for other people in a way that will give them approximately the same column drag that I have.
I attached some weights to one side of my steering wheel, having found a sweet spot on the adjustor ring that felt right. At this sweet spot, the steering wheel can juuuust about hold itself in the horizontal position, but not quite. I made a video but won't upload it until I've been able to test drive the car - hopefully the end of next week (no front bumper at the moment).
It appears that my initial adjustments a few weeks ago were in the wrong direction, having followed some instructions to the letter. Hopefully I can set the record straight soon and give everyone a clear and repeatable process to follow. I'll report back but am now much more confident that this will work after my initial error!
