IMHO, it's a great way to learn about cars, how they work and how to fix them.

I will tell you, that YouTube videos make it look a lot easier than it actually is.  The logic of taking a car apart seems fairly straightforward.  

But the actually act of doing it, was much harder, and more time consuming than I initially planned for.  Sometimes I didn't have the right tool other times I couldn't figure out a way to get the tool in the tight spaces.  And I've broken and stripped some bolts too. 

I say this not to dissuade you.  But rather to prepare you.

Scotty and the other YouTube guys make it look easy, but they have years if not decades of experience.  

1) Safety First. Especially, know the proper jack points for your car.  And always have redundant systems, just in case something fails.

2) Plan for your car to be out of commission for longer than you think it would take get it done.  There are surprises that may come up, and you'll have to figure them out as you go along.  

3) Have fun. It's quit the learning experience.

Everyone I know was dissuading to fix my own car.  It was their fear talking.  But I was eager to try and learn.  As Scotty says, "When there is a will, there is a way."

If you can do the work properly and without endangering yourself then I say it's fine. Autozone will let you rent kits to do the work so you can maybe go there and ask them for an explanation on how to do it properly, or you could also find a video online of someone showing how to do it
