Sounds like you have big problems, sounds like it has been run low on oil, and or the oil pump quit working, and you wont be driving the car much longer,it sounds like rods knocking, which means new engine time .
Its hard to say... do u know where the noise is coming from?
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.
Could be a bad strut or shock No I have disconnected both rear shocks and knocking noise is still there whilst driving. Seems to be coming from rear. When stationary I can bounce rear of car up and down and hear noise with handbrake on but not with handbrake off. Any ideas?
knocking noise
I experienced a knocking noise in my 03 Xterra and found out is was a bad wheel bearing seal and had to have the Nissan dealership replace it for about $400 (includes labor and parts).
The knocking that you are describing reminds me of a stuck universal joint. A bent axle usually wears tires out very fast more than making noise.

Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
NO. A knocking noise in the engine is a problem in the engine.
I get knocking & ping noise coming from the fuel injectors
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
if its a low knocking noise it is normal on the 3.1 engine!! if it is loud check to make sure the valves are getting oil!! I have a 2000 Malibu v6 and it is the same way.
