1000 miles and noticing potential problems

Just about 1000 miles on the new hitch I notice the bolts are "stuck" in the square tubes.

I am thinking the design is intended to allow the bolts to smoothly move based on how much tension is being applied by the rubber bushings.

Upon further inspection of the brackets i see an area where there is substantial wear on the brack from the chain links.

Passenger side below

Drivers side has less wear

Considering there is very little mileage on this hitch, I am very concerned it will not last the summer without wearing out the brackets.

I contacted Andersen the first week of January, sent these pix along with my vehicle types, weights, etc.
