this off wikipedia just for those interested:
Constant velocity joints are usually reliable and largely trouble-free. The two main failures are wear and partial seizure.
Wear in the outer joint usually shows up as vibration at certain speeds, a bit like the vibration caused by an unbalanced wheel. To determine if the joint is worn, a driver should find a big empty parking lot and drive the car slowly in tight circles, left and right. Worn joints will make a rhythmic clicking or cracking noise. Wear in the inner joints shows up as a "clunk" or "pop" when applying power or, if severe, when lifting off the throttle.
Partial seizure causes a strange "pattering" sensation through the suspension. It is caused by the joint overheating, which in turn is usually caused by the outer joint gaiter/boot having split, allowing the joint to throw out its grease.

good news and bad news
the good news is that it's too warm to produce the sound
the bad news is that it's too warm to produce the sound
it's -10 c at the moment (14 f)
and if thats the way to diagnose bad CV joints, then it's not the cv joint since tight circles in a parking lot make no such noise.

i was thinking of jacking up the front and then running the front wheels off the ground in first and turning the wheel, but my jack is leaking oil and i didn't feel like crawling under the car in the cold. haha... but i think the wheel has to be loaded for the sound to occur since it only happens when there is load on the wheel via throttle... otherwise i'm stumped... I'll try to get a video when it's colder, but next week is supposed to be pretty warm

when you go over larger bumps, do you hear a click and feel the click through the dead pedal? because I have that too, but i think it's related to the coilovers or upper strut bearing...
and i did the slow turn in the parking lot thing and i noticed that every second or so a light scraping sound would happen. it happens probably ever 3-5 wheel rotations so it's either something within the cv joint.. or scraping the snow buildup definitely not the tire rubbing on a car part though.

well, i changed the oil today so while i had the car jacked up i decided to test it with the wheels in the air. put it in first and just let the wheels spin at idle. no noise, turned the steering wheel left and right with no noise. then i grabbed the tire while it was spinning to see if it was the diff. no noise either side. then again, it is warm out.
I've never brought the car to the dealership before as I bought it off my brother-in-law so i don't really know how it works... do you just drive it in through the service lane and then they do a check over? kinda like a free estimate? definitely not going to southside though.. hate that place... i liked west side when i went over there for some parts though.
and since the service-person said it was your cv joints, shouldn't they replace it for free then since your car still has the warranty? I think it should be covered in the bumper-to-bumper warranty since it's a non-wearing item like clutches or brakes.
and i'm pretty sure the clicks are due to the coilovers, or possibly a loose steering rack.. i'll check it out.

i hate south side mitsu too lol.
just call west or north side, and tell em you need your car looked at or inspected for a problem that it's having and you need an estimate to see how much it would cost to fix. they'll probably make an appointment for ya. any time i ever had any of my cars checked out i've never gotten charged. and if i would of i'd refuse to pay.
they'll probably jack it up on the lift and take it for a drive. tell em u want to go with when they take it for the drive, if you want. ****, most of the time i walk into the shop and talk to the mechanic lol. curiosity killed the kitten.
well, he didnt say that the cv joints were bad, just that the grease is making the noise, which i doubt. i dont even think he knows what noise i was talking about and that's fine, it only does it in the really cold temps.

When I tore a boot and had to replace an axle, I found remanufactured ones here - http://www.indianapolisrackandaxle.com/
Hell of a lot cheaper than buying new ones.

I was thinking that it might be the strut bearing.... because it only happens when the wheel slips on throttle so i guess the way the wheel hops and vibrates causes the noise, and when it is cold, the bearing has a looser fit in the bushing so it'll vibrate and click... anyways, let me know if the noise comes back in a few weeks when it gets a bit colder.

Oddly enough, my car just did this during the recent cold down here. Seems to have to be pretty cold for it to happen. It only does it in the morning. My car engine was warmed up, but pulling out of my lot the steering was a bit stiff and shifting gears felt a bit funny. It made the noise on the first couple turns, but everything cleared up after a minute of driving. Later in the day it warmed up to 5 f (-15 c) and I did not have any problems on the way home. This morning it was - 10 f (-23.3 c) and it was a repeat of yesterday which was -7 f (-13.9 c) when I left for work.
Might have something to do with the power steering.
