It sounds like it would need to be inspected to assess the condition and what needs to be done to rectify the issue.

its sounding like the diff has gone. this happened to mine, on the second gearbox, and the diff and box had to be replaced again.

i take it the chipfork sound is when you are freewheeling?

sounds ok when free wheeling, forgot to mention the noise is only there under load, when i accelerate or use the engine to slow me down.

sorry to sound thick, but is the frontaxle joint inside or outside of the gearbox, can i easily check them?

1 near the diff. 1 near the wheel. Check the wheellugs too.

Thanks for that, i will have a look.

just a quick thought, if the fault was on the drive shaft then the frequency of the noise would continue to increase as the wheels get faster, this is true until i change gear, then the frequency lowers again. i would imagine that this would suggest something early on in the gear box, not a drive shaft issue. am i right or am i missing something obvious. i'm not a mechanic. thanks

Sounds logical.

Just been to my local fiat dealer who confirmed gearbox, to repair box at least £750 labour plus parts. £1000 for new box plus around £400 labour. needless to say they had to pick me up off the floor and resussitate me.
This is shocking for a 4 year old car that has only done 30k.
I have been quoted around £280 for a second hand box from a breakers or £550 for a re-con.
I am tempted to attempt it my self, i have reasonable mechanical skill and dont mind the car been off the road for a while. does anybody have any thougts on this? Is it too hard for a home repair job?

Have you done a gearbox change on a front wheel drive vehicle before..

 

[danhop]

No, but i know a man who has!
also, would you hapen to know if a box of a 1.4 will fit on a 1.6 ?
