isolators needs to be re-positioned, you can
"thread" it along the coil by twisting it by hand.
once the isolator is positioned in place, use
a heat gun or hair dryer to shrink down and
secure the spring isolators around the spring.
gradually heat the isolators until they emit
vapors. be careful not to get the heat gun too
close or you may burn a hole in the isolator.
allow the area to cool before handling.

wrap a clean, lint free rag around a long dowel
and insert into the upper tube to clean inside the
upper tube.
