Triumph TR6 - Clunking Sound from TR6 Differential

I think TR6 driving season may be over. :-(. I am getting a clunking sound out of my differential when shifting from 1st to 2nd and 2nd to 3rd on my 73 TR6. Is it time for a differential rebuild? Was in the high 70's and 80's this week in NY. Sure glad I did a lot of driving this last week. Thanks in advance for all responses.

Clunking is a usual issue with our cars. Mine came from 2 of the usual areas:
1)When accelerating, your diff twists while it torques and bangs on the front bracket that holds it. Mine cracked which I had to box in with metal plates I got from The Roadster Factory. If you don't know how to weld like me, it should cost a couple hunskys to get someone to come to your house and weld them on. Of course you should take the diff out first.
2)tr6 differential don't have tight tolerences. They tend to clunk when first accellerating. I don't think this is your problem.
I personally replaced my differential with a Nissan 300zx diff with limited slip. Got the adapters from Richard Good of Goodparts.
With these 2 modifications, I've got no clunking at all and luv ta' light up both of my tires every so often.
Hope this helps you.

Differential mounts, U-joints, a non-horizontal trans axle, differential internals ... any of the above. Check the diff and suspension mounts first, particularly if there's a rust issue.
