Hello ,
I am at a loss to get m yfront driveshaft operational .
Driveshaft Services here in Australia built me a new shaft which was too big and wouldn't fit then built a slimmer shaft which seems to vibrate no matter what they try.
They have already scrapped my old one Has anyone got a 280GES 460 front shaft.
Or any advice on egetting the thing to run smoothly ?
With the shaft out of the car everything is silent and smooth so there would appear that it 's the front shaft to blame .

Ive got a 280 i'm scrapping which has a front shaft but as the engine is blown I cant test although can look for play the old fashioned way. There is someone in Aus thats intersted in the whole interior of my 280LWB but have trid to E:mail him but no luck. If I can get thorugh to him and he want s the stuff It could go along with that. But not for at least 3 weeks :cry:

'Allo Perfect Pete,
Can you give me the silent bloke's email and I'll contact him ?

I will be going back to the driveshaft people on Thursday for a wee showdown
{ I think I'll wear ma kilt and take a Claymore along - that usually works with the English !)

If they can't sort out the vibes - I'll do a caber-toss over the fence with their shaft and buy yours but I'm up against time as I've got to go bush and take photies of coos, horsies and strange black folk.

Re: Driveshaft Blues

Snapper,

Is your suspension lifted? I ask because many of the UJ's used in after-market shafts will not operate happily at the increased angle and tend to bind a bit.

It is very often possible to take a grinder to the yokes to give them a bit more freedom.

The other possibility is that the two UJ's are not properly phased. As a UJ rotates, it causes the shaft to speed up and slow down a little (this is why it is not a CV constant velocity joint). With a pair of UJ's in a shaft, the effect cancels out, but only if they are correctly phased.

If you get it wrong, you can get huge amounts of vibration!

Change the phase by pulling the sliding joint apart, rotate one end and push back in.

Si

Re: Driveshaft Blues

Hi Simon,
I'm still working through the vibes -the front shaft is now an
original one balanced and properly phased. There is a little wear in
the gearbox>tfr shaft so that will be the next to be done.
the whole thing is bbetter than it used to be so I'll get there eventually.
Cheers Jim Mac
