Every R/C Car I've ever raced has built up "gunk" in the suspension arms. Personally I think it is result of friction between the metal rod and the plastic arm. The best thing to do it just regular maintenance. One thing though is get a fine drill, that fits snug but wont make the hole larger and twist it through a few times by hand. You'll notice some dust coming out.
When you reinstall don't use a lubricant as the gunk + lube = goo, i.e. it may mud up and be worse!
I run the titanium arms in the back of my 201 as other have said, they bent the originals, well so did I using 501X rear arms.
