strange knocking noise on my 1995 240sx

i was driving from work today and i noticed a strange knocking noise coming from the rear drivers side of my car. the weird thing is that it only knocks while im driving under 15 mph and even still it went away every now and then on my way home. the noise, by the way, i believe has something to do with either my brakes, shocks, or maybe even my wheel...got any ideas of what it could be? what should i be checking for?

Are you accelerating? My drive shaft was causing a similar noise when i was at low speeds. It finally snapped at the joints or whatever... It was never greased... Put in new ujoints and everything was great!

update:so now the noise is there anytime my foot isnt on the gas or on the breaks.i noticed that when my foot was on the gas the noise would go away but when i would let go the noise would come back. i also noticed that when i would press on the brakes the noise would go away for the time i was pressing on the brakes. what should i be looking for?!?!?!

i would first look to see if you can find anything in your brake assembly that is loose. if nothing there i would check shocks. just look and im sure you will find something.
