32 Gtr 4wd Vibrations When Front Come Into Play

[den001]

my gtr does this when the front wheels decide to engage,

its like a light constant vibration throughout the whole car,

as i bvack of and teh torque guage reads 0 or less than 10 its fine no vibration at all....

i read some other threads but they came to the conclusion that its the center bearing....

if it was the cb, wouldnt it do it in rear wheel drive???

im yet to do a oil change on the attessa system but will in the next week,

possibly a bent front tailshaft?? or CV issue??? front diff issue??

cheers

Slipping clutch packs in the transfer case maybe?

Thats the only thing that changes when the fronts engage...or could possibly be the front diff, only when it has load on it its making the vibration, but I highly doubt that one.

Transfers are usually pretty bulletproof though. Plenty of oil in it? Maybe put some fresh stuff in. (Takes ATF)

i know the 4wd light comes on sometimes as i start it, and i havnt bled the system yet as per another thread, so ill give it a go, the clutch packs i doubt are worn as it does do mad 4wd hellies.. in a private industrial area

Changed wheels or tyres recently?

wheels and tyres yes, put brand new rims , but still did this previously wih the standard wheels

will bleed on weekend

gday dont mean to hijack but mine does something very similar - only at lows speeds though while sidways (i.e.: skating a roundabout)

i thought it was because the front tyres were hopping on the road as it only happens when the car is really crossed up, is this the same with you?

If it was wheels are tyres then the 4WD and ABS lights would be on as soon as you move...

Im sorry i assumed the ATESSA was bled
