Fixing a Loose Thule Hitch Bolt on a 2 Bike Rack

Question:

My 2 bike Thule bike rack bolt that secures the rack to the trailer hitch continues to work loose even with a lock washer. I need to stop every two to three hours to retighten the bolt. Is their any way to get a longer bolt that could be secured with an nut and lock washer o on the other side?

I have a solution for you, but unfortunately the bolt patterns for most bike racks like your Thule rack tend to be proprietary, and aren't generally able to be matched.

Instead, I recommend replacing the hitch pin. You can do this one of two ways.

If you already have a lock and such set up, then part # 853-5917 will outright replace the hitch pin. Often times a bent or damaged thread pattern can cause the bolt to work loose.

If you don't have a lock, you can replace with a locking kit as part # THSTL2. This will provide a hitch lock and a new bolt and locking washer pair to replace your existing items.
