I had the same issue with my 2004 explorer... what it ended up being is that the sway bar bushings were the culprits causing the squeak. A good dose of wd40 solved that problem... haven't had a squeak since.

Speed humps and speed tables are effective speed reduction measures because they force vehicles to slow down when driving over them, making the road safer for pedestrians and other road users.

Speed humps and speed tables are effective speed reduction measures because they physically disrupt the flow of traffic, prompting drivers to slow down. Their design encourages compliance with speed limits by creating a noticeable change in the road surface. Additionally, they improve safety for pedestrians and cyclists by reducing vehicle speeds in areas with high foot traffic, making roadways safer for all users.
