hi guys.

 

Reckon i need a new propshaft as i am feeling vibration thro the drivers and passengers seat. Just wondering what use guys think? I am thinking on gettineg a house so i would quite like to sell my zed but also woul dlike to keep it and get a house. At the moment ladz would like a house then to come back to the 300zx scene. anyone help me seel my car or any tips?

I know house prices are coming down fast, but not that fast! LOL

You probably just need a new rear center bearing. As for help selling, I'm not having much luck so I think you should keep it.

The vibration happens alot when driving, i was thinking on a new full propshaft. Is it just the bearings that go themselfs that cause the vibration. How much are these parts as i have money sitting wating to get one to stop the vibration?

They are about £150 I think? MJP will be the supplier. Make sure it's not your gearbox mount too.

how am i able to check the gearbox mount? Is it expensive to have the gearbox mount replecaed?

I have been quoted £240.00 plus vat for a brand new custom length one piece prop.

where was that from mate? if it was just the on full length then it would stop vibration from happening again wouldn't it?

 

Anyone got one of these custom propshaft, and any information on the gearbox mount?

Most common issues for drivetrain vibration is the Rear gearbox mount and the Prop centre bearing. The Gearbox mount collapses over time causing the gearbox to move out of alignment which puts excess strain on the propshaft centre bearing and causes it to fail prematurely.

 

An improved design Nismo gearbox mount is around £75 and propshaft centre bearing is around £150.

 

The less common cause is the prop shaft U.J';s themselves. They can be rebuilt, or it can just be easier to fit a 2nd hand propshaft or a one piece propshaft.

 

I have a one piece propshaft on mine and it has the advantage of being around half the weight of the stock 2 piece item, which equates to better response, improved acceleration and more power at the rear wheels. If you go for a one piece then its best to replace the gearbox mount as well.

Thanks Paul.

 

I would really like to get this nismo gearbox mount then, i know its a good make but i guess it will improve the car. Would quite likea once piece propshaft, so if anyone has the one piece prop shaft and a gearbox mount then please please contact me as i will just replace both. Cheers

One piece props are custom made only, AFAIK. I will get the number for you if you like, I am seeing the man on Monday and may be able to do a deal if your interested in one as well as me.

Mine came from Z1 motorsport, they sell the Nismo mount as well, at the time the exchange rate meant it was a bargain. The props are sold on ebay as well.

is it dangerous to drive the car with this problem? I think my car must have one or some of them, it vibrates through the seat between 50 and 60.

Cough cough heres a propshaft going cheap....

awrite jimmy. I may buy that depending if i can get a full piece one at a decent price. How long do you reckon the bearings would last on it?

Rear wheels out of balance can cause this too.

It's not actually the bearing that fails, but the rubber mount encasing it. Rubber perishes, so I'd imagine a new prop bearing would give a life of 10 years minimum.

Hey Jimmy you still got the propshaft? I may be interested if the price is right
