Weird gear stick issue

[Ex-User (107751)]

Clio 172 ph2,
The problem happens either when accelerating hard with a lot of wheel spin (especially in the wet, doesn't matter if ESP is on\off), or when braking hard in gear, engaging the ABS.
In both cases, I get very severe "bang" noises from the front, massive wobbling from the gear stick, and the transmission will even kick out of gear sometimes.
Happened since I got the car,
Since then I change the engine mounts to vibra and powerflex , changed the engine and gearbox , both drive shafts , coilovers, and that's all I can think of, which could be related to this, and the problem still presents.
Everything related to the mounts has been checked many times.
I took a video showing what happens when accelerating and braking in first, note that it was shot without the vibra mounts, thus the gear stick movement on deceleration.

Is your dogbone fit the right way up?

 

[Ex-User (107751)]

Yes , bigger bush upwards. Bushes look ok, even tried to change them to a new powerflex kit actually.

Is there a lot of play in the gearstick when in gear?

 

[Ex-User (107751)]

Huge play in fact, Yanoo kit is on the way.
But pretty sure it's not the causem as you can hear a loud bang from the gearbox.

I found this,seems plausible.

Have you checked the often neglected front gearbox mount

 

[Ex-User (107751)]

My battery tray was broken and has been replaced, so it's not that
by front gearbox mount do you mean the lower mount as shown here ? http://www.eurocarcare.net/user/products/thumbnails/7700795688.jpg
It's been replaced as well

That`s the one. I wouldn`t have used an ECP one though.
Please confirm you changed the gearbox for another unit.

 

[Ex-User (107751)]

Yes, I changed to another box

 

[STEVE.M]

Yes, I changed to another box

I`ve seen anything quite like your vid.
It`s not so much a case of are my engines mounts worn etc, it`s more is the subframe actually bolted to the car?

It's like there's no dog bone lol. How has the dogbone been fitted? Assume the smaller piece bolted upright?

 

[imprezaworks]

 

[Ex-User (107751)]

It's fitted right, I even bought a crappy replacement dogbone to rule it out .
Subframe is ok, it was on and off a few times since, with no difference to this matter.

 

[Ex-User (107751)]

Update: Fitted the yanoo kit , no improvement .

 

[adamlstr]

Update: Clio 1*2 engine mounts remain utter shite. In fact no, worse than utter shite. In the history of engine mounts, no vehicular propulsion mounting instruments have ever been known to be worse.

[Ex-User (107751)]

I have the vibra ones already , and a powerflex dogbone, don't really solve the problem.

 

[adamlstr]

Oh, haha. Then check what those are bolted to.

 

[Ex-User (107751)]

Everything was checked thoroughly, the engine and gearbox were replaced by a very good mechanic, if anything was wrong he would have noticed. (Problems were already before the engine replacement.)

is the bolt that connect the tripod to the batt mount still in one piece?
mine started banging too turned out to be that bolt had been slitghly loose making the hole in the tripod oval and breaking the bolt.
due to the Vibratechnics there was no sag on that side so very hard to diagnose....
