Strange vibration

Mantegna · Jun 19, 2019

I have a vibration when accelerating, not bad but noticeable, coming from under car around prop area i think.
I have fitted new wishbones as rubbers perished on ball joints, osf driveshaft as boot torn, prop mounts.
I have a bit of play in rear diff mounts, 10mm up and down in front mount, could this be it or am i looking in wrong place.
(Freelander TD4 auto with 196000 miles on her) Any help welcomed

Is the VCU fitted on the car canter line?

Fitted it to the marks i made before i removed it. How would i check the position to be sure ?

Don't know if this could have caused the issue but i fitted a 50mm lift kit month ago

If it was okay before fitting the lift kit then..........there's good chance it's the...................... lift kit

Yes. It's the 50mm lift kit causing the vibration. This is due to the inner CV joints being worn to a set place. When they're asked to articulate more than previously, then the joint gets forced to run outside it's worn area. If left like this, it will damage the output bearings of the gearbox and IRD. You need to either remove the lift kit, or replace the drive shafts with OE or genuine shafts. Don't be tempted to use cheap shafts, as those vibrate anyway, causing the same damage.
