Repacking Bearings? - Trailex Trailer SUT200s

I just purchased a used trailex SUT200s Trailer for my Pro Angler 14 and the guy I purchased it from told me that I need to repack the bearings. I am very new to this and not very handy. I wanted to know how do I go about repacking the bearings. I can't seem to find step by step instructions online and I have no clue what I'm doing. Please help me if someone knows!

Here is a very good 9 minute youtube video to view and see if you want to tackle the job.
The title is "How-to guide on packing trailer bearings".

If you feel you are not up to the task, most tire shops or a local auto repair shop can do the work for you.
In any case, I would have Bearing Buddy's installed so you can add water proof grease with a grease gun.....this is about a $60 investment and worth the cost.
