You still have to get the car to the mechanic, wait for it to be finished (or started from my experience). You can do all of this yourself with a basic toolkit and a youtube video playing next to you in 2 hours. So the time you're sitting waiting and paying someone else to do it someone else to do it you can do it yourself for substantially cheaper.
You'd probably need a 14mm wrench, maybe a 10mm, some red grease.. and that's about it.
