Troubleshooting Blue Ox Tow Bar Inner Leg that Won't Release

Question:

I have the 15,000 lb Blue Ox tow bar kit. It’s 6 years old. It’s got to where, after towing my 12,000 lb Ford F350 crew cab diesel. The release handle does not release. Does it need maintenance or a rebuild kit?

Most likely maintenance so that is what I would try first Randy. It is recommended to lubricate the inner legs of the tow bar to make sure they stay in good working order.

Use a silicone based lubricant and NOT a petroleum based one like WD40. The other joints use self-lubricating washers. If the joints are stiff use mild soap and water to clean them.

Basic maintenance is as follows:

Periodically clean the entire surface of the tow bar with a mild soap and water solution. Wipe dry with a clean cloth.

Check for cracked welds and repair any loose, worn or damaged bolts, rubber boots or cap plugs.

Approximately once per year or if it is difficult to move the legs in and out, remove the small cable ties holding the rubber boots to the legs and slide the boots back. Clean off the inner legs with a silicone spray or brake cleaner. Apply a light coat of multipurpose grease to each leg to ensure a smooth operation. Secure each boot back in place with an 8 inch UV rated nylon cable tie.
