well i just got my damn header leak fixed and theres another god damn problem. I hope anyone of u know what i'm talkin about, well when crusing down when i make a turn but only to the left I dont know why theres like a rattle coming from the right rear tire and i'm not sure if there has to do with the suspension or something but i'm getting really desperate. any comments on what can it be ??? can it be the cv joint axle
No, unless you've got a Cobra IRS, there're no CV joints on the car.
Have you changed the fluid in the differential/rearend?
If so, did you add friction modifier to the oil?

well it was changed when the 3.73's were installed, but can that be the problem because it's almost 5 months that they were i installed and the problem just began yesterday.
Are you sure it's coming from the rear? Inspect underneath the car.

grab The Tips Of The Exaust Pipes And Shake Them See If They Are Lose Or If You Can See Maybe A Muffler Lose Or Not Placed Right. I Just Fixed A Problem Like Yours My New Flowmaster Super 40's Were Not Straight And It Kept Knocking Like Yours.
My car did the same thing after I put my after cat on. I just did a little adjusting to the tail pipe. It only happened when I turned right. It's gone away now.
