weird noise and feel

[spiff325is]

okay, this happens mostly in 1st gear, but occurs sometimes in second.

when i floor it on turns or off the line sometimes in first or 2cnd gear, or if i just give it little more then normal throttle, i get this DUDUDUDUD, not like im bogging or anything, perfect power, but it feels like there is someone or something shaking my seat, like a paintball gun set at 600psi is hitting my chair(or undercarage) like 40 times in 5 seconds...

my friend that it thought it was my LSD being gay, and that made sorta sense, like the LSD is just messed up and kept thinking i was losing traction(when going striahgt my tires have perfect tracion, but still do it).

odd..

anyone know what im talking about?
anyone wanna help?

(there is no clutch slippage or any bad shifting or nots on the gearing when i shift, everything is smooth, its just a weird dududududu)

are your wheels spinning or are they moving at a normal rate of speed? my car does that when i floor it in the wet... wheel hop or something

perfect traction, it just makes that noise. i know it isnt my clutch, a lot of my car=knowledgable friends are convince its my LSD just acting up, it only does it sometimes...

your LSD bushings/mounts or whatever they are called.
