Wedge TR8 rear end noise?

My TR8 has 21,000 miles on it. When the top is up I hear the rear end is pretty loud. Sort of grinding/bearings noise coming from my passenger side. I jacked the car up and spun the rear end and it all sounds just fine and spins freely. I thought that there was a grease fitting back there but I don't see one. I'll top off the gear oil, but does anyone have any thoughts? Are the rear ends just noisy?
 
This is just standard noise location 101:


Generally, an axle bearing noise can be discrened by loading, i.e. slight left turn loads RR bearing, etc.
If the noise increases for the side being loaded, that's probably it.

If the outer race is piting, lack of weight on the suspension will sometimes cause them to be quiet when checking in the air.
However, using your hand on the carrier, while spinning, you can often FEEL any roughness you cannot hear in this test situation.
 
Hi Larry - I don't get any noticeable noise from mine, and given the hard life it appears to have lived that make me suspicious of what you are hearing.

My guess is that it is the bearings and not the differential itself.
 
I had a similar noise from my TR-6. Thought it was coming from the rear. Turned out to be a front wheel bearing. Might be worth checking.
 
If your problem is inside the center of the rear end, the noise should change when you get on and off the throttle. If the grinding noise is coming from the wheel area, it might just be the brake drum rubbing against the backing plate, or the shoes dragging. Isolate the noise and then start taking things apart. The causes of noises like that tend to reveal themselves pretty quick once you start unbolting things. Good luck.
