Agree with Randy,
Check the shock mounts. Had the same problem on my TR3. Would get noise on bumps and couldn't fine the problem Finally got loose enough that I could move the shock. Mount holes were rounded out by then. ISTR that there are no lock washers on the mount bolts.

Moss-Europe still shows the kit for the TR2-4 live axle cars.
It seems a bit involved with brackets needed to be welded to the differential axle tubes.
A couple of thoughts on the rattle - I'd check the shock links very carefully as one step. The rubber inside the link can perish so you can get a rattle even though the link looks ok. The number one problem I had was the lever shock mounts would come loose and the shock would move a bit creating a noise. Those bolts are hard to access, some use a socket headed bolt to get better torque on them.
If you are convinced its the shocks, you could test the theory by removing them and driving around for a while - the car will bounce more but if it still rattles it means the shocks weren't the problem. I had a rattle from the muffler hitting the frame which might be a possibility.

When going over bumps in my TR4 I have quite a rattle from the right rear area of my car. I have poked around by the axle, and thought I have fixed the problem a couple of times. I have replaced the springs and refilled the Armstrong shocks. I have poked around. While looking through my Moss catalog I noticed the kits for replacing the Armstrong shocks with these brackets that you could mount shock absorbers to. But the kits are NLS. No Longer Supplied. I was wondering why the kits were discontinued. It could have been that they caused damage to the frame, or just didn't work. I was hoping somebody had any first-hand knowledge or experience on this topic that they could discuss. I wonder if the racing group all have custom and proprietary set ups.
