hello all,
First time for me here on this forum. the name is jan and i am from the Netherlands. we bought a t3 syncro several years ago in Germany,and converted it to a Westfalia camper. i also put a golf 3 tdi 1Z engine in it. about 2 weeks ago i had my very first test drive with it.and noticed that there was a ringing noise from under the car. we removed the propshaft and the noise was gone. i searched on the internet and found several problems what can cause the noise. we inspected the propshaft on his joints,rubber coupling,and bushings but i didn't see any defects there. we measured and adjusted the angle of the front diff and gearbox flanges but there was no change. we overhauled the visco coupling,because an x ring was leaking. i replaced the diff mounts and gearbox mounts with the ones from powerflex. today i made a video. you can hear the noise when the clutch is released. it makes the same noise when i drive. only not so loud. in third gear with wide open throttle, it sounds like there is a loose heat shield. https://www.youtube.com/watch?v=canHB9ig1Ao&t=32s so you can all hear the sound. i hope that someone has a solution for this. |

I get something very similar but haven't found a solution. I'm told the propshaft with the sliding joint will help, but I haven't tried it yet.

Have either of you looked at the mechanical joint behind the rubber doughnut?
There is a steel shaft through the doughnut which engages in a bronze bush set inside the main tube. I found some wear there allowing slight sideways movement. I tried stripping it out, cleaning the shaft & bush, applying grease and re-assembling it rotated by 180 degrees. This caused an improvement and reduction in noise. |
