I've put on a gearbox and diff and rear subframe from another car with less km and the vibration got worse than before. Even worse when I went from 19" to 16" wheels. Also replaced the bushing with energy bushing on the subframe and diff.

There was no vibration from the car I took the parts from.

 

I don't have the car right now. (in poland to change the sills) But I have tried to rotate the 1 piece driveshaft 180 degress. didn't help. (90 degree was not possible. The holes did not match on the aluminium part/wheel on the diff.) (the aluminium parts has got a few dents in it.....

 

I'm guessing the bushing change might have enhanced the vibration ???

At what speed do you get vibrations ?

The vibration is always there. Increases with speed. I've done 160km/h once but the vibration was so bad that I was afraid to drive faster.

try a standed propshaft with a known good bearing

only one problem. Haven't got one. maybe order a new 1 piece. recomendation?

Get a used but good OEM one from a scrapper, or see if someone can loan you one.

 

Pointless shelling out £250 on a 1 piece if that's not what is causing your vibration.

Got a price from s scrap dealer for a 2 piece here in Norway: £ 274.

Any recommendations on a good 1 piece vibration free driveshaft??

Zedworld do them.

Or get one of the people who break cars here to post you one over. I'm.sure someone would do you a good sale or return deal.

The Aluminium prop has dents?-i would have that looked at and balanced before buying another..

what is dented? if its the flange and the faces arent mating 100% square you will get vibration.

the aluminium rear coupler has dents in it. But the matting of the driveshaft and aluminium coupler seemed to fit. I have always had a bit of vibration after I got the 1 piece. Thinking when I changed to poly bushing that might have increased the vibration feeling....
