A cluck from the front!

A cluck from the front!
Hi all, this ones got me. I noticed a clunk from the front of my ZT, this happens then driveing along and i take my foot off the accelerator pedal, about 1 second later there a clunk and then i change gear.
This sounds to me like a engine mount then the engine comes on/off load.
The lower engine mount was changed a year ago, ive checked the o/s mount its ok, n/s mount checked best i could without removeing battery.
The cars just been mot and passed with flying colours, but i have just rechecked all front ball joints/bushes etc all fine.
Ive checked driveshafts both fine.
Im thinking may be gearbox as then i had the front jacked up and in 1st gear, if i spin one wheel by hand theres a clunk from the gearbox as the differential starts to turn the other wheel.

The thing is now i know its there i can hear it above the radio!

Have i missed something?

What do you think?

Rear lower engine mount, known as teardrop mount, common problem, best check it again.

not cheap i'm afraid. around £80 for the mount IIRC around 30 mins DIY fit.

I assume you have checked void bushes but you tend to feel them on the brake pedal.

Cluck form the front, made me smile

checked your grill for chickens

i get a clunk when stepping on the accelerator or letting it go under any speed, i also get a wheel jerk is it the engine mount?

Possibly, or rear mountings on front arms, there are other possibilities but these are the most common

Lower engine mount.--

When I saw the thread title, I really didn't know what to expect when I opened it to read.
