How can a bad uni affect turning ?
If you have a Trac lok lsd set up. I've found the last clutch plate (closest one to centre on each side) are prone to fracturing and breaking.
And they will start to work there way out, and jamb on the inside of the diff carrier.
And I'm sure rattle gun use (vibration whilst stationary) makes the broken segments vibe out.
Had almost identicle thing happen.
But luckily this happened when leaving my driveway.
And no major damage to carrier.
Undo the diff cover and fully inspect clutch plates.
