Vibration/shuddering/judder under acceleration

Hi everyone, traded my twinair punto for a AGP Today, and wasnít able to get the car on a fast test drive, on the way home unfortunately I noticed a vibration/juddering only when accelerating. The car has been lowered so Iím wondering if itís driveshafts? Gearbox seems good but did contemplate differential? Any help greatly appreciated, hoping I havenít bought myself a dog 😔

Could be a number of things..

Check tyre pressures first.
Check wear pattern as it could be tracking and poor alignment.
Overall tyre condition ok?
Could be wheel balancing.

Always check the simplest things first....well thats my mantra

Hi there, and sorry for the slow reply. I’ve been told there’s a part that runs through the centre of the gearbox that could be worn, but struggling to find a name and part number!

I was told driveshafts are less than 6 months old but I’m not ruling them out!

I’ve removed the coil over kit now as it was stupidly low and this has improved the shuddering/judder loads, but it’s still evident when pushing hard, seems worse in 4th although this could be my imagination.

She’s had a gearbox rebuild so I’m hoping it’s not a sign of bearing failiure as the gearbox seems quiet other than that!

Many thanks for the reply’s ����

Ash

Re: Vibration/shuddering/judder under acceleration

What have you replaced the coilovers with?..did you change the top mounts too?

Coilovers can play havoc with the driveshafts and whilst I know you said they were 6 months old do you know if they were a quality part ?..irrespective they could be fubarred ..BUT your only getting the noise/juddering in a certain gear at certain revs/load?...
