i have noticed a little knock coming from the fusion sounds like it is coming from the rear of the engine. well i have been thinking of causes low oil, ect. then it dawned on me the knock started right after i wrecked the car. i hit a curb going 40 jumped it and back down. is there a possibility that this jolt could have messed something up

Check for a exhaust leak. This can have a ticking sound.

or any clearance issues, or dents along the bottom, what does the oil pan look like?

farthest in it hit was a control arm and its not a exhaust leak as it sounds real solid and increases perfectly with the engine revs

okay thanks for a couple thoughts i have convinced my mom to take it to ford now anyways so im not going to bother looking at it now as i wouldnt be able to fix it if i found it due to warenty lolol

I say take it to the dealer....it'* under warranty..
