Vibration at acceleration

[Edgar]

I have a vibration at acceleration, specially when I accelerate hard. I was told it could be the GUIBO or the driveshaft carrier. Has anyone here had the same issues and did I you figured out what was it?

Vibration where? What steps have you taken to eliminate other possibilities? Who told you what? A technician or a random stranger.

Could be tire wheel imbalance, alignment..

I have a pen.

When was the last time it didn’t vibrate? Did anything change in the car since then? How’s your tire pressure?

Tire pressure still the same, nothing change since last time it didn’t vibrate. I noticed after I did a few pulls one night and the last pull I notice it.

Do you have a log? Maybe you’re misfiring

I get vibration rattles in my speakers under hard acceleration with ASD on, could it be that? It’s super annoying and only happens at certain RPMs during hard acceleration,

found the issue?

I found out that my tire pressure gauge was bad. I got a new one and realize my tire pressure was way off in one side. Filled both tires the same way and still vibrate but not as much as before. I read in another group that welds racing wheels are hard to balance and they also loose balance, so I am thinking it also could be the wheel balance is off

i recently have the same issue. My Supra is a stage 2 with mhd. I think with the tune it puts more stress on the guibos so the rubber just wears out faster. I replaced mine a month ago and all the crazy vibration when I accelerate was gone.
But recently I used mhd anti-lag and pushed the car a good amount and it started to shake again. Seems like the front guibo is now gone. Not sure what a better fix to this is. These flex disc are just wearing out very easily with just stage 2 and anti-lag.

Maybe a diff brace. The issue might not be the power wearing the flex disk but the angle changes when the extra torque is applied to the diff housing and the resultant movement. This will stress the rear flex coupling more. Bad engine and or gearbox mounts will stress the front coupling more than normal.
