Loud Knocking Coming From Diff Area

[Taso84]

Basically, was drifting, and on one of the drifts, my cars back wheels started bouncing up and down due to no traction.

Straight afta that i could hear lound knocking noises coming from back wheels, especially when appling throttle,

The knocks are even more so when i'm turning and the car is in gear at and gear at any rev range. It feels like im losing power everytime a knock happens and then another knock happens and power is regained. when the car is in neutral nothing happens.

I'm thinking the bouncing up and down has screwed my diff.

Any thoughts pple?

Well its axle tramp that you had initially...

And my bet is the diff mount has now broken and is moving around etc.

Any suspension place/good mechanic should be able to let ya know.

expensive to fix? Or just a matter of welding it back

Not sure on the R33, but HR31 mount is rubber, around $350 from Japan + fitting.

Go get it looked at i guess, only thing to do. I might not be that, could be something else. Impossible to tell over the net for thigs like this
