This post is about an american supplier for the bearings in Brenderups. I am pretty certain that they don't change bearing sizes between the various Brenderups, but I will give you the details.
Jane C. from New Mexico was looking for bearings and brakes and Andy in NH was out of stock.
Here is the item on Amazon <<<
The part number is 513113 Auto Wheel Bearing, 39mmx72mmx37mm, Sealed. Priced from $18.95 and in stock in the US! If your mechanic should have your trailer apart you can have them measure the inside and outside diameter of the bearings without even removing them from the wheel.
These can be installed by most mechanics. When I did mine I took the brake drums to a mechanics who pressed out the old bearings and pressed the new ones in for about $20.00
Jane is also looking for replacements for the gas booster cylinders that help lift the tailgate. If anyone has come up with a suitable American Made replacement please let me know.
Happy trails... Jeff Kurtz
