Hey everyone I have a 2010 Honda Accord LX and about four days ago it suddenly started making a thumping vibration sound that sounded like isomething stuck in the tire or we had a flat we did pull out a rock but it still does it it only does it on acceleration .we had taken it to our local mechanic yesterday morning he put it on the lift didn't see anything out of line but when he drove it he definitely heard the sound he said it's coming from the driver side it could be the axle but he can't be one hundred percent sure does anyone have any ideas what it could be because we'd like to have it fixed as soon as possible but if the mechanic isn't sure what it is how can I fix it
