It started three or four days ago... At first I thought it was something in the trunk rolling around during turns. What gives? Is it a differential problem, something loose I should worry about? Thanks for your opinions and advice.

Check the rear sway bar links. Common problem, easy and cheap fix.

Len

also check rear half shafts. the cv joints may be going.

..I also have a 427 Cobra replica with an aluminum chassis.

its also a good idea to change the diff fluid to a good synthetic

Len, what should I look for and if it's that, what's the easy and cheap fix? Even if you just direct me to a website that explains it or other source, it would really be a great help and very much appreciated.

Tom, same thing here, what to look for, what to do about it. Where can I get an explanation of exactly what to check... what to do?

What do you guys use for that? Only God knows what's in it right now. I bought the car two years ago and the EZ Lube guys checked it only once (even though at each and every oil change they marked it on the service report as checked) and said "it was OK"...

Thank you all for your help,

Rino

One sway bar link on each rear wheel running vertically. They are about 6 to 8 inches long, plastic and bolted on top and bottom. Unbolt the old, bolt on the new and you're good to go. Cost ought to be under twenty bucks total.

Len

turning both ways, or only one? maybe bearings.check for play by jacking up and wiggleing the tires.

I run mobil 1 75-90? gear oil in my rear end.

half shafts- look to see that the boots aren't torn.

the half shafts should have no vertical play if grasped and wiggled up and down. you need to park the car with it in neutral and with the parking brake on so that there is no stress on the half shafts.

Turning both ways... but it seems to make a louder noise when turning right, though I am not 100% sure about this.
