torx tube queey

[cococola]

Is it possible to get a clonk noise through the torx tube due to bearing wear and why would you normally replace a torx tube?
thank you

Not too sure about a clonk noise. When does it occur?

I rebuilt mine with new bearings, as a distinct rumbling noise could be heard coming from inside the transmission tunnel at idle.

It might be worth having a good peer inside the inspection grommet holes (items 4, 5 and 20 attached).

Its my doink doink noise that I still have,after replacing the driveshafts and rear shock absorbers I dont really know where to go next[]
The noise is similar to a cv joint clonk when pulling away and sharp turning.
I did wonder about wheel bearings but ther is no play or noise when spinning up the wheel.
Any advice where to go next would be really gratefully recieved.[&o]
many thanks

Did you try rocking the car back and fourth with first or reverse(lowest) gear engaged to see if the noise can be heard.It may be the clutch centre spring drive starting to fall apart,all the best John.

Do you have the steel or aluminium rear trailing arms?

I once had an issue with a 'doink doink' sort of noise, under the same conditions, on an early steel-armed car.
It turned out to be due to a cracked inner thrust washer (item 2 attached). The bearings themselves were in remarkably good condition, spinning the wheel showed no play or noise.
I would be surprised to find the same problem on a later alu-armed car, due to the more modern one-piece sealed dual roller bearing design.

I'm scratching my head to think of other possibilities [&o]
- De-laminated rubber on the Gearbox mount(s)?
- Rubber clutch spring/damper on its way out?

I wonder if it is possible that the inner bearing is causing the noise?
I will try the rocking in gear this afternoon.

I'd be really surprised if its the TT causing the issue, have you checked all other options?

 

[zcacogp]

Why do you suspect the TT rather than the gearbox? Those could be the signs of a worn diff, for example.


Oli.

I replaced the gearbox about 12 months ago and it still appears to be fine.
Im just running out of ideas now[]
