One after another, just got the flywheel done and fixed FINALLY.

I thought this problem was casued by the flywheel but it isnt..

THe car has a hard vibration.

Ex, when the car goes under load i feel the car start shaking BAD... but once i get off the gas its gone... i could be crusing at 80MPH and NOTHING.. but as soon as i give the car GAS it starts wobbling... now at slower speeds i hear something under the car toward the front end making a weird noise..

like somethign rotating and hitting something when given slight gas..

i know i need rotors and brakes but this wouldnt casue it

i know it isnt the flywheel or clutch since there a BRAND NEW flywheel and clutch in there installed by maximum tunning (and yes its been doing this B4 the install)..

any input.. i really wanna get to fix it tommorw since its my day off.

Thanks,

motor mounts?

 

did you get any light?

 

damn q, all this car is doin is givin u problems. i will be in queens tomorrow, maybe i can help diagnose the the problem. its rob from nycmax, you got my cell

 

Sounds like inner CV-Joint boots are torn. Those can be checked for free, rule them out first.

cv boot and mounts. i recently did mine both. so check them both out. i kno exactly what u talkin about. dont drive it too hard, my axle broke down on me on the highway at the time

 

100% cv axles

 

I had a crazy issue like this on my 3.0

first thing i need to ask you is if you have an underdrive pulley, if you do then i can help you out.


I had the same problem with my 3.0, no one was able to figure it out, then i just kept driving it and i figured it out.

It was my motorstorm underdrive pulley, its a two peice pulley, and at point were the two peice were colted together, it lossned up.


If you dont have a pulley, its most liky your axles

 

Well Rob this car hasnt ever really given me problems except fot the flywheel and this. Hey Rob im working on the car at my boys shop out by sunrise hwy. ill give you a call if you wanna come by.

Hey maxspeed yea i DO have a UDP from unorthodox, ill take my stock UDp with me and switch them out i guess.

My axles are MINT... when i did my tranny the axles were really good the boots werent torn or anything... arrr

 

what brand do you have, cause i had to motostorm one, im just curious, but if its loose bent or unbalanced it will cause vibration.

 

Does this occur at idle or only while driving? Brake-torque your engine to place it under load without moving to see if its simply motor-centric (and nothing to do with the drive axles).

 

it only happens when drivign under load.

Changed BOTH axles.. put back the STOCK UDP.. balanced the tires.. put brand new rotors and brake pads in, checked the wheels bearing.. EVERYTHING is GOOD. Im stumped. Im sitting in the shop right now with the car on the lift..

 

ninja edit:

 

this car is gettign annoying.. i couldnt fix the problem i spent alot of $$$ buyign all these new parts today (well brakes etc etc were needed still).. and broke the holder for the shifter linkage thats on my 6speed tranny.. it was cracked and when i went around the block for a test drive to see if it was still fuked up it decided to go..arr..

alSO my tensioner stripped.. im so fuking pissed and fed up !

gatta wait till monday to order those parts from nissan...

any thing else you guys suggest i check for tommorw when i go back to the shop ?

 

Damm, i broke the tensionor before to, **** was pritty hard to change cause its impossible to get a hand in there....

Since its only doing it underload, its something related to the tranny or motor i assume?

The only other thing i can think of is the wheel bearings, but those would make lots of noise if they were shot?

 

I am having the exact same problem as you man, I tried looking at the axles and they were good, then someone told me that it was the strut mount...checked that and it was good, this has been one of the only problems that I cannot figure out, and also it only does it when the car has load on it...but let me know if you find out or I'll let you know if I find it out...

 

Maxspeed96... werd man i jsut changed the tensioner got the belts on all good etc.. finally ! lol

Pimping02max... Ill let you know... ive gone and checked everything i could ! but nothing. Im thinking it could be my Coils ??or a bad plug?? maybe 1 of my injecotrs not firing right ? so im going to try swappng all that stuff with my buddys motor and see if it works.. if not the car going to a shop so they can play with it . after tuesday im not ganna try lol. ill DEFENITY find out soon whats the problem.

 

Alright, cool man, and good luck with everything...hopefully it's nothing to expensive

 

Seems there's a few of us with this problem. Have you found the solution? A mechanic friend suggested to me it was the motor mounts.

 

I don't think it's the motor mounts becuase mine just started doing it badly whenever I lowered it and I wouldn't think that would affect them, also I just put new motor mounts in about 40,000-50,000 miles ago...but you never know it might be...
