Q: Knocking noise

asked by on October 31, 2017

Just started about a day ago when I am driving and coasting meaning I am not accelerating or tapping the brakes my car makes a knocking noise similar to if your lug nuts are not tightened or the wheel is not on properly but I checked all of that and those two things are not the issue. I also looked underneath to make sure my tire was not coming in contact with anything which it seems not to be. Any ideas? Thanks.

My car has 112000 miles.
My car has an automatic transmission.
