Gearbox Noise / Oil Level?

[AndyH]

Hi,
Yes, jacked the car up and checked. Nothing obvious.

Sorry to ask, but what's the correct amount of oil.l think I was using 1.6l. Does this sound right?

Google is your friend:

2.0 litres from totally empty cold . 2.1 litres when performed while fluid is warm.

Thanks Chris..
I've just been doing that... It's always good to get another opinion, so many thanks.
I'll drain /re-fill this afternoon, but I don't think this will fix the noise..

Lots on then internet about diffs "exploding" on the 6sp boxes.

Has anyone had any experience with a noisy diff pre failure / or the intermediate shaft bearing failing and symptoms?

Diff failure occurs when a pin holding the pinions makes its way out of the diff. Have you got plunge in your cv joints on all suspension travel?

Hi,

Now got 2L of oil in the gearbox... A bit embarrassing to think that I filled to the dipstick rather than to the correct volume of oil, but I've done worse I'm sure!.
For info, the "black" dipstick above from the Alfa166 / old 164 gearbox was the correct level in a Stratos with 2L of diff oil in.

CV Joints / spacers etc are all as original HAWK spec... so I'd like to think they have travel in them OK.

Just put the car up on blocks and run... No noise, but a very obvious vibration at around 40-50mph (Hard to tell cause my mechanical speedo no longer works ,and I'm still waiting for "Speedy Cables" to send the electronic version). Less speed OK and more speed OK, but there is a range where the vibration is very obvious.
That sort of ties in with what I hear on the road.

Tried rotation again on both back wheels and it does feel like the vibration may be coming from drivers rear... It's also a little out of true.

Off to the garage to check wheel balance and see if any of that helps.

Thanks for the comments above.

Hi,

Just been out with a "spare tyre" I had.. A bit of a different size, but I hoped it would prove a point.

Sadly noise still there.

I've just changed the bearing on the rear passenger side... Long standing "play".. that's fixed now with a new bearing and a bit of bearing lock..

The bearing on the drivers side does sound a little rough by comparison, but it's only done about 3000 miles since it was changed post accident.

The hubs I have take the 164 bearing.. Do these stand up OK to wide rear tyres (315), or do they still suffer from short life?

The noise is certainly there in a certain speed range. It's obvious in a straight line and around right hand corner. Left hand corners and it disappears.
This would suggest more load on the suspect bearing though??

For background info... All was good until I had a Cadwell Park track day last year.. I noticed the noise starting on the journey back.
