Hi, im just curing a vibration problem on my fairlady lwb non turbo,

 

Im almost sure its a prop problem, the conversion is:

 

Car was a auto, converted using a tt box, it runs a n/a diff and n/a rear prop, with front prop from the tt, but i get a vibration, the centre bearing is new!.

 

Im thinking to ditch the whole lot and buy a one piece prop but will this be available to buy with my tt box and n/a diff!,

 

any links would be great, cheers!.

I have seen that if the rear gear box mount is crap it will cause problems aswell??

yeah, checked all the gearbox mounts they all look ok, one is that the vibrations seem to quieten a bit when the car is warmer

dont know if this will help ?

The 2 prop sections might be out of balance with each other. Sometimes turning the prop 180deg helps, by that i mean, undo the bolts on the rear diff so the prop is not connected, rotate and rebolt.

For a one piece in a configuration you want, check out JeffTT's thread on one piece props.

Groover sent you a email bud

 

Sorry for the high jack :)

Replied :wink:

I had some bad prop vibes some time ago........

I thought it was the centre bearing, but it turned out to be the UJ joint on the 2 piece shaft.

I got a custom made 1 piece prop shaft from Z1 motorsports in the US.

Great price and fast delivery, with a small import tax.

 

Got it from here...http://www.z1motorsports.com/product_info.php?cPath=6_11&products_id=1831

Try a Nismo gearbox mount first, this helped me when I had some vibration problems, much cheaper than a new prop. The old one had gone soft and had collapsed.Ebay USA will be the best place to look.
