Tailshaft Question!

[Keeper]

i split the tailshaft in two pulling the motor out but forgot to mark on the shaft with paint so i can bolt it back in line the same as before with out any rotation, will this be a problem???

it can cause vibration. see if you can tell which way it goes on by looking at any scratches and marks and see if you can get them to line up.

I've never bothered marking on a couple of cars I've done and not had a problem. Maybe make sure your tailshaft is balanced OK if it vibrates

Re hashing an old thread..

I have what Iam suspecting is an unbalanced tailshaft.

I have changed the driveshaft bearing.

The drive line shudders and vibrates at low RPM.

At idle when the clutch is in its quite as a mouse. When I let the clutch out I head a large "thud" (clutch) then a "whiring" noise.

Now.. my questions are:

1) Roughly how much does it cost to balance a tailshaft? (any dieas in Syd?)

2) If I get a single peice shaft do I just slap it in or do I need to balance it once on the car?

3) There a diffrence between GTST and GTS4's tail shafts?

Cheers guys!

Assuming that you have a 2 piece shaft with a rubberised Uni joint in between (like I did on my previous R33 GT-R), is there a certain amount of give in the middle?

This would indicate that the tail-shaft needs to be changed.

Another symptom of a weak tailshaft is that when travelling at constant cruising speed for a few seconds or more, the car starts to vibrate. The vibration stops as you accelerate or decelerate. I variety of different (maintained) cruising speeds would expose a weak tailshaft.

I think I know what your talking about!

At around 100km/h+ there is a certain accelerator position that I cant keep the pedal at or else it starts to vibrate. If I go past or before the certain position the vibration stops. Problem is that BEFORE the certain pedal point, the car decelerates. If it push the pedal PAST the vibration point it begins to accelerate.

So the certain point is my constant speed. So yes, I am getting what your describing.

Question is;

Roughly how much and how long to get the shaft balanced?

Ive got an r32 gtr and I get a clunk noise when changing gears, i had a look at my tailshaft and noticed the centre shaft has rubber seal of ring that holds it this is not broken or leaking any fluid but i can move the shaft up down left right about 10mm either way. does this mean its time for relacement?
