I have a 1991 CRX Si. Yesterday I started my car and usually don't put my car in gear (Manual), well this time I put my car in gear and forgot and let the clutch out while it was running and it slammed into the curb, enough so that it lifted my whole front end up.

Today before I drove it, I checked underneath and there was no damage surprisingly it didn't even crack my bumper. I drove all over today probably 80 miles with no problems, and I was going to go get gas a little earlier and I put it in neutral and it just starts making a really loud knocking sound, not the engine but it's coming from the front left wheel well. It only does it when, I put the car in neutral or don't accelerate. When I put on the breaks it doesn't make it, but the second I let up it starts knocking, and the faster I'm going when I put it in neutral, the more knocks it makes. I checked underneath and didn't see any damage. What gets me is that it doesn't do it when I accelerate. Anybody know what is happening?

 

does anybody know?

 

Start removing things around the drive-train on that side until you either find something broken, something hitting the drivetrain, or something else all together.
