get gear but no drive ?

[lil3520]

wifes 54 reg 1.2 has just broken down.

loud bang then can get a gear but no driving forward.

had a new clutch 18 months ago.

what would be the loud bang ?

engine still runs.

if its still selecting gear but doesnt drive then is the drive shaft not snapped or popped off?

 

[lil3520]

if its the driveshaft, how much will that cost ?

cheers

 

[mr_D]

scrap yard is the best place to have a look, i have no idea mate

 

[lil3520]

car has been towed to a garage. waiting for the call from the wife !!!!!!!!!!!

 

[mr_D]

hope its not that bad dude. there are a few things it could be be being able to get into gear but not drive is weird. unless its clutch related

 

[lil3520]

wife has just phoned me, garage think its the driveshaft. will get it confirmed whe garage ring her up in the morning.

my mate knows the garage owner, may get it done cheaper.

 

[mr_D]

Not to sound dumb, but how does both driveshafts snap at once?

If it's anything like my old Cavalier. 1of the driveshafts hadn't been hammered back in enough after one of the cv gaiters had been replaced.It eventully popped out one day when i was doing a Starsky and Hutch style getaway.It wouldn't move at all, even though it was just the one.Exact same symptoms,no drive but everything else working fine.
Got it done by someone who knew what they were doing after that.

If the speedo still goes up when in gear probably a drive shaft, if it doesn't and it went bang then most likely the diff has gone. We do loads of them

 

[lil3520]

thanks for your replies.

will keep you posted.

They won't have done.

If you lose one shaft then because there's no load on that shaft all the power will get sent to the broken side because of the diff.

Then wouldn't you drive round in circles?

Is it the 1st of april today?

No.

The diff will send power to whichever shaft is easier to drive - this is why your car can get stuck in mud easily - the spinning wheel uses all the power and none gets to the other wheel that has traction. (This is a simplification - but close enough)

If one drive shaft is broken then all the power will end up being sent to the broken end of the shaft (that should be connected to the wheel). No power will get to the other shaft.

Some light reading for you -

(In particular the bit about loss of traction)
