Question for Hensley hitch owners

I just towed for the first time today with our air ride TS 3(only 5 miles) and noticed a clunk when starting and another clunk when I stopped. Any ideas? This hitch is brand new. I found the grease fitting and lubed it but am unclear where to use the spray grease mentioned in the manual. The pictures are black and white and hard to see exactly where to spray just under the plate that swivels. Thanks for any help. David
