Hey everyone,
This is my first post here.
Im hoping someone can help me lol
So yesterday i drove my jeep to work and noticed a very low knocking sound.
When i was exiting the freeway it shut off on the on ramp.
The battery completely died.
I went to autozone had them charge the battery, then she started right up.
But there was a really hard and loud knocking at the bottom of the engine.
Sounds like theres somthing in there being thrown around.
Can some one please help me

 

Is it coming from one particular side or directly underneath? i swore mine had a knock but was confused at why it was only on one side. Turns out it was the EVAP solenoid inside the driver side fender. Might be something to check.

 

Post a video of the sound.
