Bang, Clatter but nothing obvious
Discussion
Ian. My two penneth worth. Has anybody already said? Jack the rear wheels up off the ground, on safe stands or a lift.
Run through the gears gently. Then at low speeds try stop rotation of offside and then nearside rear wheels to see if the noise can be reproduced and located, again using the gears. The last operation may tell if the diff and CV joints are suspect. I did this to check my speedo sensor. The first op may tell if the problem is with the prop/gearbox etc. Be safe and good luck.

Yeah, yeah, yeah.
I hear you, and the diff is on its way out to go to the nice man who will fix it, but without being able to diagnose the fault with the car in the air, there was no way I was going to all the trouble and expense of pulling the diff without investigating the other possible options first.
This is the electron microscope picture of corrosion on one of the balls in one of my CV joints. All 4 CVs had at least 2 balls in this state.
Would you have ignored this and still pulled the diff out?

How many miles has your 1992 diff and CVs done? Keep us all posted on the final fix. Good info on GKN diff CVs. Quote by Steve Heath "When these joints (Lobro CV) are worn, they become noisy start to clank, especially when setting off". Sounds like your "bang and clatter"

And so the saga continues...still had a duff, duff, duff, duff noise which increases with speed, but which I discovered I can make go away by either depressing the clutch or feathering the throttle to reduce load...
but to keep the thread going a bit longer, have you checked the clutch bearing? :wink:
I'm ignoring the lot of you, though some of you deserve stitches 
Actually, I've been a bit poorly so didn't want to be in a cold garage, and now i'm sunning myself in Spain for a few days.
I'll be dropping the diff next weekend and we'll pull the back casing off to have a nosy inside because I'm still not happy we haven't been able to find the fault, and I'm curious what it looks like inside an LSD
I'll then be dropping it off at a place I found recommended in Hinckley, Leics which is local to me and who has quoted 425 +vat for a recon unit so at the worst I can just buy one of them.

So you think it may be the diff now Ian? Wonder what gave you that idea?
