Knocking in Transmission tunnel following an enthusiastic Blat!

[jskyrme]

I have been enjoying the car today.. .probably a little too much and have ended the day with the expensive sound of knocking coming from inside the transmission tunnel when turning right...

 

Having limped the car home I jacked the car up and could see (what I think is called the propshaft?) which seems to have shifted over to one side of the tunnel and be the cause of the knocking.

 

Is there an easy fix I'm missing or is this a garage job...?

 

Many Thanks...

Check the propshaft bolts that connects to the rear diff - 4 bolts (probably blue)

Check both engine mounts first - they could simply be loose or they could be broken. If both engine mounts are solid then it could be the gearbox mount - again could just be loose. To check the gearbox mount you'll have to get underneath the car.

You should be able to get a finger in betwen the gear box and the nearest chassis rail on both sides - if it is close or touching on one side then the engine or gearbox has moved on it's mounts.

After doing a clutch change I had exactly the same problem. Checked all of the above and finally narrowed it down to the tunnel sides being slightly caved-in after lots of poking around in there during the clutch work.

Bit of leverage using a two foot breaker bar sorted it.

Checked Bolts on Propshaft to Diff (you were quite right, they were blue ) and they seemed fine...

 

Engine mounts also ok (they have recently been done.... ...checked gearbox mount (two bolts only?) and loosened them off and found I could man handle gearbox away from transmission tunnel just enough...could see any any other mounts....hopefully this has done the trick...

 

Thanks very much for help guys...look forward to testing tomorrow if not raining too much 😬
