Engine tapping, oil is fine what could this be?

Hello, the engine tapping is far more concerning than the rear wheel squeaking. Tapping is an indication that somewhere there is a lack of lubrication getting to where it needs to go. This could be due to some sort of clog passage, incorrect oil viscosity, and oil filter that is causing a restriction of flow, or perhaps some sort of where that has occurred already in the engine that is unresolved. Hands-on testing is needed, get a pro near you to have a listen and make good recommendations before driving any further. More driving and more tapping could mean more damage! Beyond that, the rear wheels should be removed to inspect brake mechanisms to determine if there is a problem with the installation or components of the brake system.
