This is an odd rattle, my axle seemed to check out ok.

Here are the symptoms:
- Rattle on the left when turning right, but only under acceleration
- rattle on the left when hitting a bump but going straight

The sound really seems to be coming from the suspension it self. I would say my struts and springs have 100,000kms on them, seems firm. Could it be a strut mount?

My tie rods and ball joints are only a few years old and they are tight, no play.

 

Suspensions don't really rattle. What makes you think its the suspension?

 

take a vid
i think by now we all have 1080p phone?

I had a clunking sound I thought was something in the suspension but it was actually a broken motor mount.

 

Nope. My Blackberry Classic won't be here until 2015

 

Let's stay on topic, mmmmkay

 

Check your swaybar links, inner/outer tierods and your lower balljoint!

 

Also, check out your engine mounts, especially the passenger side mount and driver/transmission mount ............

 

I tried this before posting, but my exhaust drowns it out in the recording.

I trust my mechanic as I've been going to him for 15 years. But now he has kids working for him, I admire that he honors any screw ups and doesn't charge a dime to check anything. Places now will charge $80 even if its a quick look. But I may have to get a second opinion.

 

You can look at this stuff yourself....by putting your car in gear, applying the E-brake and foot brake,while giving the car some modulated throttle in R and D! Even the suspension can be inspected for free by yourself....just jack it up and place on stands, get a prybar and start checking play of bushings, balljoints, swaybar, swaybar links, etc...DIYer for life!!!!

 

Try to pull ebrake while driving straight over bumps- I was hunting for months for rattle created by ebrake hitting exhaust under the car. Pulling ebrake tightens the line and if it's the culprit you will hear change in the sound of rattle. In my case it disappears completely.
