Got a problem Iím scratching my head about and would welcome some ideas.
Iíll give you the background so you have the whole story.
Feb 2010 clipped a traffic island in the snow, not going that quick (20mph) when I slid out on the apex of a corner. Damaged the left front wheel and CV joint. I was left with a nice clunking sound whenever the steering was on lock. Found an Alfa breaker and bought a cheap replacement. Tried to fit it but found the hub nut was wielded to the driveshaft. Took oxyacetylene and 4hrs to shift it.
Jul 2010 CV boot split, drove regardless until the CV joint was making knocking sounds on almost any lock, (not straight ahead) With the car jacked up on one side, I could grab the CV joint and twist it without the wheel rotating.
Oct 2010 Replaced front wishbones.
Dec 2010 Finally got hold of another second hand driveshaft with a good CV, a replacement teledial and also bought a new CV boot and wheel bearing for good measure. I should mention, apart from the very obvious CV joint noise, there was nothing else untowardly wrong. For the first time in 10 years I paid a garage to do the work and carry out an MOT, everything passed with flying colours. (Didnít fancy doing it in the snow
Now, all the clunking has gone but a few days later a new noise started. It only happens occasionally, and seems more pronounced when the car is cold. When I turn a corner, left or right, I can hear a slight grinding sound coming from the left front. It seems totally random, doesnít happen on every corner I must add, sometimes its totally silent. Can be heard in gear and neutral and with the clutch engaged.
Iíve jacked the left side up and there is no play in the driveshaft anymore and no obstructions around the disk. If I spin the wheel I canít hear any signs of a wheel bearing failure or the grinding heard while driving a corner.
You should also know that the clutch is on its way out, or so I believe, biting point is quite high now. 1st gear has also become noticeably stiffer to engage recently.
The only thing I can think to test now is to stick the front end on stilts and go through all the gears on tick over, left to right hand lock and see if it appears under engine load.
Iím freaking myself out itís the differential.
Apart from the obvious problems with the CVs Iíve never heard a peep out of the diff. Could it be another dodgy driveshaft? Dodgy or badly fitted wheel bearing. Something else? Or am I about to be the newest member of the Diff non-appreciation society?
Any ideas or suggestions extremely welcome.
