04 350z So about a month ago I left my ebrake on when getting on the highway (ik im dumb) and when accelerating my car started violently shaking, fastforward 2 weeks and it happened again, no ebrake tho i was just accelerating, now the same thing happened yesterday 3 times, it doesnt happen if i accelerate slow but if i give it a good amount of throttle the rear end just shakes like hell and my slip light starts coming on, any help would be greatly apprectaiced TIA.

 

Step one would be checking if the brakes are dragging, in which case you’d be fighting that and would get a vibration because of it. Otherwise just check the basics, bushings etc…

 

I posted a video, if i wouldve kept on the gas it wouldve just kept on shaking, i got scared and let off lol, and the speed and rpm it does it at varies, i tried to reacreat it several more times and it pulled fine, happens just every once in a while but its slowly happening more often, i have a warranty on my transmission that i put in myself so if i find out its the transmission i need to make sure ive changed every possible bushing on the tranny to make sure they dont void my warranty, I blew thru the tranny cooler lines before intsall, and my struts might be bad but it doesnt seem like any sort of bushing, seems to violent to be that.. my U joints are most likely bad aswell because it clunks when i put the car in any gear (the light shaking after the car sounded like it **** the bed is the hood, it rattles alot im not sure why)

 

bump
