How to fix Coleman camp trailer lift system, ball bearing whiffletree replacement

I show how to replace a whiffletree lift system on a Coleman Tent Trailer. The old ball bearing system broke and I replace it with after market whiffletree. My trailer is a Coleman Sequoia 1986, 24 foot long. The whiffletree is 28 3/4" long. When you order the new whiffletree they give you options to the length of the shaft, so this video can be helpful to people with trailers other than the sequoia.
