I have an Falcon 5250 Towbar that is 11years old and was showing its age in that one arm was hard to extend with the bushing sometimes coming out with the arm. I downloaded the instructions from the website and felt I could do the tear down and rebuild.
Since I don't get to any rallies, and wanted to get this fixed I ordered the repair kit from Roadmaster. ($50.00 with postage) The kit contained everything to replace parts that wear and age out at stress points on the arms.
The instructions were great and had pictures with each arm having about 25 steps in tear down and replacing. Once the arms were apart, I found them extremely dirty inside the square tubes. Cleaned them like shotgun barrels and sprayed them good with silicon. No problems at all in following the directions and best of all no parts were left over like some of my other projects.
The tow bar is as good as new and no special tools were needed. About a 2 hour project working as slow as I did.
