Hi I'm just new to the triumph club. Bought my herald in  May 2016, has been restored, however at end of September started getting knocking sound from either diff or uni joint..! When I turn left or exilorated the knock stopes. Any thoughts.

get under neath and check the half shaft UJ. they should be tight in the circlips. I guess a few miles has bedded them in and may have some movement now. You can check with a screw drive placed across the UJ and check for movement.

Have a read here;

Don't forget that it could also be the prop UJ's and also noise can get 'thrown' in unusual ways, such as a wheel bearing sounding like rear right but it's actually front left etc.

UJ's are the most common cause, but any joint could be to blame, diff mounts worn etc, or in the case of my old Herald, the rear spring mount plate was snapped in half!

Check all the flange bolts are tight first.  These like to work loose.

As Pigboy says :http://www.canleyclassics.com/technical-archive/rear-end-noises
but checki9ng for wear as he suggests is unlikely to be much help as it has to be very bad to be visible.

The noise you describe sounds very like U/J.  They knock when unloaded, so when you turn left you load (I think) the right hand U/J.  Also loaded on acceleration (no knock) and unloaded (knocking) on over-run.

(ticking and knocking are different, but that's not an issue here, as you are looking to replace.  BTW, I don't know if Rarebits is still trading)

I'm doing a few shows, as well as supplying some of the more obscure (but easily packaged) items through ebay. I've also helped a few people with odd one-off pieces through direct enquiries, but the online shop is closed. I simply can't put the time into it alongside my paying work.
Let's just say that if it's a commonly available part, other suppliers will be able to help you a lot quicker than I can...

Cheers,
Bill.

Forgot those , mine worked loose, but that was something to do with a size to small bolts after changing the diff and being in a rush to finish and not noticing the new flanges had larger holes.
