On my U320,
on the suspension system,
on the rod that controls the ride height valve...
What is that little rubber angular boot that accepts the rod, and holds the clamps? I found them with a rod kit, but the display did not mention the name of the specific part.
One of mine is a bit crumbly. The steel rod is fine!
I doubt it has a specific name. What you said - "little rubber angular boot" - is as good as any.
IIWM, I'd just buy a linkage kit, use what is needed, and put the rest away for future use. But that's me...
