Have 1999 R93 with trailor that has Coolhub, upon inspection today port side hub sticks 1/4" & you can see that levelis full (bubble @ top of glass)you can also push the glass in until it stops with about 1/16" sticking out, starboard side only sticks out 1/16", you cannot tell if it is full, you can push glass in but barely any at all. Does anyone know what is up with this, what is correct or need corrected?
