Ok so I have a feeling that this may have came when I was driving home at night, ran over a 2x4 and it broke underneath my car. I lifted the car, noticed a piece of wood stuck underneath, pulled it out drove around and the noise was still there...

It comes from the Driver side Rear Wheel area (maybe not wheel but suspension, I don’t know)... It happens randomly, sometimes when I make a right turn, you can hear it. When I drive off it comes... and by the way did i say it is really embarassing?

It goes
Tick....tick..tick.tick.tick.tick (as I accelerate)

Any clues?

1988 300e, I never had this problem until I ran over that piece of wood...

Did you check your tires for blistering, or see if the tire is rubbing or both?

Could be the parking brake cable got tweaked. Could be as bad as a rear axle half-shaft needs to be replaced...

Yes i checked the tire, no rubbing at all the wheels fine..

I lifted the rear end of the car up and accelerated as it was jacked.. the noise is really loud and somehow sounds like the drive shaft.. rear differential. maybe a flex disc? i'm going to replace my flex disc, i have a feeling thats the problem.

or you could have busted a tooth in the differential by popping it in gear foward or reverse.....has happended to me in a firebird.

Check the rear axle half-shaft joints might be out of grease...

i have a feeling this may be a possible winner. it does sound like its coming out from there, but its intermittent.

if the sound is random i doubt it is anything that is rotating IE gear teeth, halfshaft, etc. get it back on stands and run it while looking around and listening carefully. apply brakes while noise is present and see if it changes anything. does the noise change with increased rpm/speed? if so, it would not be considered random.

Solution!!!

Ok so just as I thought, my rear flex disc. I had it on the jack, gassed it up a bit and had my brother hit the break, it made the noise. the flex disc was MISSING A BOLT.. how the hell that happened, i don't know.. it was worn out..
Replaced it (took 10 minutes) and the car drives like a dream! No sounds, no shakes, rattles, vibrations, nothing. I'm so relieved.
