This is the mechanical mystery that baffles all mechanics within (at least)
a 50 mile radius of my hometown:

Over late last year, don't ask how but my Achieva became submerged pretty
deep in a mudhole. It was to the point where the body of the car was
resting on level ground, meanwhile the front bumper had extended across
the length of the puddle and was somehow holding up the car and the tires
were just dangling. I'll never forget the awful cracking noise the car
made as it came to rest.

Anyway, somehow my roomie and I got it out in less than an hour, and it's
never skipped a beat as far as engine/transmission goes, but it's been
making this awful, annoying grinding sound when it takes off ever since.
To more accurately describe it, it almost sounds like the driver's side
tire is flat, or like the car is just spinning the tire above the ground
and it's scraping along the pavement. As the car changes gears as normal
and gets going pretty good, it fades out to - forgive me for using this
example, but - something that sounds a lot like someone hitting a bong. It
seems to only come from the driver's side front tire, and can't be heard
from the outside of the car.

As of recently I've noticed that the sound will reoccur for a short time
if, say, I'm going over a dip in the road at a good rate of speed. That
leads me to believe it may be my shocks and struts, but I'm really not
knowledgeable enough to say for sure.

I had a couple of mechanics tell me it may be in my tire. In response, I
put new tires all the way around and still the sound remains. I take it to
another mechanic and they said it might be my axle/joint. I had all that
replaced too, and that didn't work, either. It doesn't seem to be
detrimental to the vehicle at all, I'd just really like to know what it is
so maybe this time I can actually fix the problem, rather than just putting
new parts on my car.

I greatly appreciate any advice anyone has on this issue.
