i looked under my 71 bronco today to try and find out what was causing a rattling sound. on top of the d-20 t-case i saw a little cylinder going up towards floor about an inch high. it was topped off with a metal cap (the whole thing looked like a mushroom). the cap was loose and was causing the annoying rattle as higher speeds. what is this for? can i just use some silicone and keep it from rattling? thanks, i know this is a shot in the dark
