Replace the Harmonic balancer

My 2000 Grand Prix would have a low-speed knocking noise coming from the drivers side as the CV axle was failing. The loss of lubrication in the CV Boots allows the joint to make a knocking/tapping sound at a low speed. If the knocking is coming from the engine compartment, then it could be an entirely different problem.
When making changes to a car it is important to have a diagram of the area. The wiring harness diagram to a Pontiac Grand Am can be found in its maintenance manual.
The ignition switch in a 2004 Pontiac grand am can be installed by first Sliding out old lock cylinder and then Press the small release tab While turning the key to the ON Position.
Internal knocking inside the engine is almost always a sign of worn bearings. Crankshsft, or rod bearing would be my guess. The fix, if it is internal, is overhaul. Before opening it up, make sure the knocking is indeed coming from inside the engine.
First, check the lug nuts. If that's not it, check the wheel bearings.
Pontiac Grand Am was created in 1973.
The Name
my grand am had an engine knocking noise. it was the intake manifold gasket was going bad. it was leaking coolant into my oil. look at your oil to see if it is a white milky color. if it is then you need a new manifold gasket which sucks. it takes a long time to do by yourself. or you can take it to a place that charges you $1000 to do. but if you can. do it yourself
