A mate of mine has an Evo VII GSR..The car in question has ACD and AYC..

When driving a low speeds if you turn a corner you can feel the transmission winding itself up (slowing the car down) it then causes the rear wheel to hop (like a locked diff)

We have pulled off and taken apart the transfer box and its all in working order. The gearbox seems 100% nothing unusual with it at all and as far as we can tell the AYC is also in working order.

If you jack up the rear end both wheels spin freely and the problem does not show itself...I have no idea what is causing it and i thought someone on here may have had this problem....

Whats really getting me is there are no bad noises from anything..No clunking/grinding or anything like that

Any help greatly appreciated...

Anyone got any ideas...We have diconnected AYC and ACD and its still doing the same...

 

Hi, Phil
first clean your ABS sensors and try again with ACD, AYC see what happen.
I has the same problem before, it is because ACD & AYC working with ABS.
hope this can help

using correct case fluids is also important

 

UPDATE:

Right so far we have replaced the rear diff, transfer box and gearbox as well as cleaning the ABS sensors and the fu*king thing is still doing exactly the same thing...I have disconnected the AYC and ACD and driven it and it keeps on doing it...Got her hooked up to a MUT II shows no faults and all systems working perfectly......

Spent 10 hours on it today and still no closer to finding the problem...I advised him to buy a 5 litre can of petrol pour it into it and set fire to it....

Does anyone have any ideas ? Willing to try anything at this stage...I refuse to be beaten by a car....
