I have this issue for several years now. Maybe since I've bouht this tungy.
Steering is very heavy when I'm parking. Even hard to turn with 2 hands. But only on very low speeds.
Once car is in normal driving, I do not feel it heavy.
Car is oem height, 13" oem wheels, yoko A048 (semi slick). Pressure 1.8bar.
It is not sticking. It's just heavy. No strange sound.
What to check? Could it be the column bushes? The rack?
If the front is on jacks it is easy to turn.
