Wondering if anyone has any ideas?? has 120,000 miles on it. Seems to have small leak under rear. Umm Tried spraying wd40 seems to squeal worse. Has gradually gotten worse. Not sure if wc40 made it worse or just coinsidence. Just had shop replace fuel pump. Came home couple days later started squeaking whining. Not sure leaf spring someone said. Just wondering if anyone had any ideas what I should check. Noise worse at take off but does it now even driving. Sounds like coming from rear end.

May have a wheel bearing going out or a bearing in the differential if the sound is different under acceleration than it is not under a load.
