Drivetrain noises

Like ice in the wet....I can only imagine.

Good you got it sorted out

Good find. Glad it is getting sorted

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.

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
