Full of grease. This has been something Dexter came out with many years ago....in my opinion the folks have not been doing it right.....thus Dexter now says pull yearly. I have two trailers with this ...my 2010 Montana wheels have never been off....original brakes too. This fall I purged one tube thru EACH axle until new grease appears. I may have it wrong ...just my experience ....I'm estimating 75,000 miles. I had 10,000 miles in first three months.
