Ive never tried this so im not sure if i should just hand it over to a shop or would it become apparent what i need to do when I go to try and replace it.

any help is great, thanks!

Replacing the seals isn't that hard. you have to take the lower part of the strut loose, outer tie rod end, and pull the axle out. use a seal puller tool or pry bar to remove and the proper seal driver to install the new. make sure you get your seals from toyota, i messed around with ones from advanced and stuff and the are to big to go in. not to mention the ones from toyota cost less.
