Could be a worn CV joint

If a 1996 Cadillac Sedan DeVille is making a backfire noise from the engine compartment while at a steady speed, it is probably due to a bad oxygen sensor. The vehicle could also have one cylinder that is not firing or a problem with missing exhaust or the catalytic converter.

Could be a wheel bearing, better have it checked out soon before the wheel departs from the vehicle.

Could be Luxury Sedan if its a car.

I'd like to know who keeps knocking on our door. I'm just asking if you've seen who it is that keeps knocking on our door. I suppose you could be the one who's been knocking on our door.

loose rear caliper or drum brakes, could be loose hardware or on disc brakes, possible warped rotor

Sure it could. But it could also happen in a sedan.

The knocking noise could be one of several things. The wheel bearing, a worn steering or suspension part, or road debris could be causing the noise.

A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.

If the brakes are too loose that could be a result.

you could have a wire broke in the tire

it could be your valves or your engine
