Juddering by acceleration C5 X7

Post by Cveto »

I have the following problem:
During our recent longer trip I found out that by heavy acceleration there is juddering which you can realy feel. It happens between 60kph and 110kph, then it dissapears. When I lift my foot off the pedal, it dissapears. So when the car is coasting, or you just keep the speed, you cannot really feel it.
It is mostly noticeable when entering highway, when you go from 40kph to 120kph quite quickly. By higher speed, up to 150kmph, it is not there anymore.
I have tried accelerating in different gears, but it is not engine rpm related, only speed related.
Car data:
C5 X7, 2.0HDi 163PS, autobox, 2014, 190.000km

Any ideas?

Hi, and welcome.

Are all the wheels balanced?
Are all the tyres properly circular and running true? Jack up one wheel at a time, rotate by hand, and check.

Hello Chris,

thanks for replying. The wheels and tyres have been checked, they are OK.
There is a strong suspicion that there is something wrong on the half shaft.
Does anybody have a similar experience?
Could I have the part numbers for the right and left half shafts and flanges for my car? So everything from gearbox to wheels. I would like to check the prices on Autodoc.
My VIN is VF7**************[VIN obfuscated, can be read by forum staff].
Thank you.

My local mechanic (no Citroen expert, but OK) diagnosed the problem as "something wrong with half axle". He proposes replacing both, left and right. Could I get the part numbers for these for my car?

Thank you.
