Bravo 1.4SX - clonking and flapping sound

Hi NG,

I have a Bravo (N reg 1995 approx 96k) with a problem and I'm hoping that
somebody here will help. I am not very mechanically minded so I will try and
explain as best I can.

Went to leave work the other day and reversed as normal and though that it
didn't sound right. Put full lock on to pull off and it made loud clonking
noises. These noises continued all the way home and it also seemed to
struggle to pull off from a standstill. Occasionally, there was also a
'flapping' sound. Had no problems getting it into gear or using the clutch.

Anyway, got it on the jack today thinking that perhaps a bearing had gone
but there doesn't appear to be any play in either front wheel. However, when
I turn the wheels by hand they both make some odd noises. There is a
wub-wub-wub noise which comes and goes. The wheels also lock until I give
them a good shove. If I turn the wheel forward and then back it really
locks. I am guessing that whatever it is, it is affecting both wheels but
have no other ideas.

Any suggestions anyone?

TIA

Glenn

Sounds like you have extreme CV joint (constant velocity) problems.
CV joints are the articulated joints that allow the wheels to turn
(left/right) whilst being driven through the drive shafts.

You will have at least two CV joints.  The out ones are located directly
behind the wheel hubs and have the drive shafts going into them.  The second
pair are either near the gearbox (each side) or integral with the gearbox.

Jack the car up and secure on stands, one wheel at a time, and rotate wheel
with one hand whilst holding the drive shaft with the other.  Look and feel
for play and noise.  May get worse with the wheels on full steering lock.
WARNING!  usual safety please.  Rotating the steering with any wheel in
contact with the ground whist the vehicle is on jack & stands WILL
potentially make the jacking unsafe.  Lower and re-jack between steering
rotations!

Thanks for the reply. The problem is now big time - no forward gears at all.
Time to get rid.

Thanks again.

From what you are saying sounds more like gearbox now, possibly the main
diff has gone.  Difficult to say for sure.  If the rest of the car is ok and
in good working order binning it might be and expensive option.  There again
this might be just the excuse you are looking for to spend some money on a
new toy :-)
