Faulty propshaft, clutch or gears?

Post by benjileo » 13 Jun 2019 12:24 pm

Hi all,

In the last couple days I've noticed a grinding/rumbling sound from underneath the gearbox

When the car is in neutral and the clutch is out there is an audible rumbling that goes away when I push the clutch in.

When changing gears this rumbling becomes more of a grinding sound and is louder the higher the revs - this makes me think it's more likely to be the prop?

I had the clutch replaced less than a year ago. Having done some reading it could be a loose bearing perhaps, but I was told that my prop was looking a little worn last time I took it to a garage, which makes me think it's more likely that.

If it is the prop, does anyone know where I can source one (can't find any on ebay) or perhaps know of other models that will fit the 340?

Cheers,
Ben

Hello, I think the propshaft is unique to the 340 and is very hard to find nowadays. I don't have much experience of propshaft problems, thankfully, so sorry I can't be more helpful in diagnosing the problem.
1988 340 1.4 GL, 218k, 5 door (Grey Bess). Gone to CBA.
1991 340 1.7 GL, 64k, 5 door, petrol blue (Deep Blue).
1988 360 2.0 GLE, 140k, 5 door, ocean blue metallic (Blue Bess).
1989 340 1.7 GL, 108k, 3 door (Red Ness).
