rear diff "throbbing"

Am a newie here, car is an EVO5 gsr...I noticeed when i push my car hard in hairpin turns...1st gear speeds or wider hairpins at 2nd gear speeds, it feels like my rear diff is throbbing, kinda vibrating thuds...what is this??? I was told that it is the electronically controlled rear LSD.

My question...Is this normal for the electronically controlLed LSD? Can it be cured by a oil change?
An friend also told me...changing the rear diff to a clutch type LSD will eliminate this throbbing sound substancially....any truth to this?

I'm unsure if the evo 5's have acd but even so that only controls the front diff. Normally the rear is a helical LSD. Swap fluids and check your rear bushing maybe they are bad. You can also get solid mounts for the rear diff from AMS. Good luck

thanks for the reply....

They say the rear diff (EVO5gsr) is electronically controlled that has something to do with the AYC. Its my first time with evos so I really do not know what the throbbing/thudding sound is on hairpins when I am hard on the power....but it really could be the electronic diff trying to engage...hmmmm....hope to get more help in information!!!!

I hope someone can shed more light regarding the electronic rear diff before I buy a clutch type mechanical LSD which was standard on the EVO5 RS.......

Thanks again...I also found out there is some kind of hydraulic pump in the boot which is filled with ATF fluid and the lines I believe are connected to the diff....so it makes me believe its not a standard clutch lsd....

sounds like the mounts are busted or fluid is low and is making it slip....change the fluid and check your mounts....I have a IX with the ACD. The sound you are hearing is not normal nor is it good.
