i discovered new sounds when driving today. i have never heared them before. first appeares when the car spins tyres and LSD kicks in, for example wot in first gear. its a strange constant grinding sound, like wuuuuu coming from the gearbox area. also i hear something like duk duk duk at the same time.
I think another one should be either engine mount or tranny mount. it clunks when i press clutch during decceleration.
what do you think? do these 2 problems have one reason? loose or bad tranny mount for example?

 

When was the last time you got under your car and messed with it? What did you do while under there??

I noticed a strange rattle/clicking sound when I changed out my DP the first time. I had not seated a stud properly and it was causing vibrations. It could be something as simple as that...
