How to stop friends from seeing "liked" posts from public FaceBook pages?

[RandomGuy]

I figured out that all my friends could see my activity on public FaceBook pages. I didn't want them to see what I was liking and commenting on so I looked at my account and privacy settings to see if I could change this but I didn't see anything. Is there a way I can make it from these posts appearing on my wall?

The only thing you can do is head to your timeline, Scroll down till you see a LIKE box, and hover over it until you see a Pen looking button, click it and hit Hide from timeline.

NOTE, that it MAY not hide your likes from the ticker. Which is the crap I HATE the most, the ticker!!

Go to your account setting. Click on custom and make it only me.

Hide your recent activity on Facebook.

Remove recent activity stories by clicking the X that appears to the right of the story when you move your mouse over it.

If you want to prevent people from seeing a recent activity story about a change in your basic info (ex: changed relationship status):
Click the Edit (Update Info) button in the top right corner of your profile (timeline) and find the field you want to edit. Before you edit it, choose Only Me from the privacy audience selector.
Make the change and then view your profile (timeline). You may see a story about it, but because you selected Only Me this story is only visible to you.
Delete the activity story from your Wall (timeline).
Go back to your Edit section and change the audience of that section back. Because you deleted the story from your Wall (timeline), they won't see a story about the change you made.
