Cars bottom(front) hit the ground and after few miles it started making this noise plus it started shaking when accelerating on first. It does this sound only at drive or reverse gear and is affected by speed, not rpm.

I dont have any good places where i could go under the car easily so id like to know what im should check when i somehow get there

 

Maybe you've got a bad driveshaft ujoint that what it sounds like you are discribing...Bill

 

i dont think the video link wasnt working, but it should be viewable

 

I 2th that Sounds like a bad U joint

 

ok thanks, gotta get to it

 

Went to car repair and the mechanic checked the u joints and found nothing, didnt know what to check next.
And since the sound comes only when in drive or reverse (stops when shifted to neutral while moving) i shouldnt be any bearing either

 

You might check and see if the trans inspection plate is rubbing, Might check the front brake dust shields for rubbing. Check the spark plug wires ? Maybe the motor moved and busted a plug ??? It sure sounds like a bad U joint ? If you still haven't found the problem ? You need to physically take the drive shaft out to check the U joints Could have a rusty one making noise without being loose

 

Your guy needs to run it on the lift or jack up the rear with the tires off the ground and run it yourself.. It is a ujoint just starting to go bad...And it may not be loose yet...Bill

 

three things I would check.
1st check to see if you damaged your flywheel or the plate covering the torque converter, while there check to see if any of those bolts connecting to the torque converter to the flywheel got loose.

2nd check your motor mounts and transmission mounts.
it is quite possible you broke one or all of these mounts and with power being adding added in drive or reverse, the motor might be on a weird angle or is stuck in a bad angle with the drive shaft rubbing on a cross member or the exhaust or straining the rear. If all the mounts are broken it's also possible the motor pushed back on a weird angle from impact pushing the drive shaft further into the trans straining the drive shaft. I am saying this because you had an impact. Check this yourself have a buddy look at your motor, put your foot on the brake give it gradual gas and see if the motor lifts, do this in drive and reverse.

Also Check your shocks if they are too low from what happened (blown) this is a long shot but hey you never know looks like you got a big boat.

you did say the noise stops in neutral correct?
#2 that's my bet

 

U-Joint or a Loose Wheel Cover !!!!!!!

 

could be a bad oscilator valve or a the micro nut in the rear pump on the front brakes.retighten the muffler bearings and back the torque off a little on the speed limiter for the front u-joint.also check the air pressure of the spare tire.

 

Lol

 

oh I forgot, change the Radio oil and lubricate the antenea bearings. if that doesnt work rotate the air in the tires.also check the altenator fields are cooling properly.
