**More problems Popping Noise from the Brakes or Rear.

[UKcuda]

I was going to say the same about the additive - I bet you it was that which caused the noise etc.

I had the same thing with an Isuzu Trooper a couple of years back - they can go with a hell of a noise when you try to turn, even going slow.

I think what happens is the diff. stays put and the tyres flex to take the strain until it can't hold anymore and then....CLANG!  it resonates down the prop. shaft.
