clunking noise when letting out clutch changing gears

[Sdavne]

90 na when I let the clutch out when changing gears it jilts and makes a clunking noise, I was thinking maybe the u joints but not not 100% sure any thought or suggestions, thanks Scott [email protected]

could be bad u joints or just wear and tear on the diff gears. how many KM are on your car?

the chassy has over 189,000 miles so if i replace the driveshaft witch i am plannin on doing will it help i am also looking to a new rear aswell, but hopefully it will stop all the grinding and thunking

Clunking like two metal pipes hitting each other or whining/hissing like fast spinning metal on metal contact?

[Sdavne]

its more like a thump, it feels like i am gaming the clutch out real fast even when i let it out slpwly, its not a metal sound but you feel a jolt in the car when it happens.

Rear diff bushings. Have fun changing those...

[Sdavne]

Well I am getting a new diff, and the bushing are polyurathain and they are newer.... if we are talking about the same thing, the bushings as in the inserts that hold the diff in place; I need a whole new rear and I want a new driveshaft as well.

[Sdavne]

And why is the bushing hard to change? From what I hear taking out the diff is not to bad but I might be mistaking

This is an old thread but I thought I might try my luck. I am getting a similar clunking sound when I let off the clutch quickly. Doesnt happen when doing it slowly or normal driving. But in my case I hear it where the trans is or right in front of it. And I also feel it i little in the pedal. The car is one Im looking to buy as a working project. 120k miles manual trans. All the fluids were flushed and the trans mount was replaced. Any Ideas guys?
