Hello everyone! Yesterday I've noticed that my bumper has dropped barely an inch, but it's noticeable to a perfectionist ( like me ). When I go to push the bumper up on the sides, it's loose. However the front side is still stable. What can be done to fix this?

I've heard of the rear bumper mounts failing but not the front ones.

Thanks everyone and have a good weekend ahead!

 

You answered your own question here, you have to make sure the supports & mounting hardware is tight/secure. With the cars' being as low as they are, the dips,scrubs etc. sometimes bend the mounting brackets &/are loosen them over time.

 

There is a bumper cover "guide bracket"(17 in this image) which mounts to the inner fender.
Either hardware is loose or something broke.
You'll need to remove the bumper to get at it and see whats going on back there.
