Uh.. I might be retarded here.. what kind of noise does a tight rear LSD make? The diff has 29mm of breakaway torque.

Is this normal? Its similar to this

Okay so I've been driving it around, tuning ECMlink and generally enjoying how well I have the thing sorted, but I note - the car is still clunking from the rear.

So I have

- Fairly fresh gearbox and transfer

- rebuilt diff

- rear inner CVs are rebuilt

- I have no 4ws anymore, and the rear toe is fixed. 

The clunks happen in two different ways, and I can't work out a way to diagnose it!

Both of the clunks only happen at low speeds, with the clutch partially engaged, and mostly from a stand-still.

- With the wheel turned, it makes a clicking sound like a messed up CV

- sometimes, when I'm accelerating from stand-still, it sounds like the rear is taking up slack with a fairly loud clunk. Sort of a scraping then clunk noise.

I'm thinking transfer case? It doesn't sound like a wheel bouncing from the diff being locked, but then again for the most part it makes noises when the wheel is turned slightly, so wheels going at different speeds... 

At all other speeds and particularly with the clutch out it is totally fine. 

Ah! I swear I replied to this.

After looking into it a fair bit I found that they use the same wheel nuts as the ford fiesta, the taper is slightly different and they have a captive washer.

Perfect fit and when I torque them they don't back off anymore. The other nuts I was using was also wearing the wheels directly - not these though due to the captive washer.

Only thing that sucks is the quality of the stock fiesta nuts is absolute shit. Will eventually find a higher quality replacement. 

You had any luck with this? Curious.. it's been on carsales too for ages.
