Front bumper squeeking
 

Got a MY03 WRX. Not sure if this is a major problem or owt but its buggin me, the front bumper has been squeeking for the last year on and off, have put some cable ties inplace on the bumper and then onto the inner wheel arch to help but its still doin it. Also all the inspection panels on the front bumper are moving/loose as in theres alot of play in them. Subaru replaced inner wing but problem persits any help on how to cure this would be appreciated that doesnt involve replacing bumper as im skint!
