No it's not my passengers whining about the stunning acceleration


I have just bought my second 9000 Aero (1995). The car has done 66,000 miles and previously spent it's entire life in London.

Driving along in third gear I can hear a quiet whine from the gearlever which is not apparent in any other gear.

As a city car, I suspect it spent a lot of it's time in third gear, so what are the warning signals I need to look for, should I get it attended to now rather than wait for it to get worse ?

Thanks in anticipation of your comments.

Just in case you all think I am a bit ignorant, I did read the previous posts of a few days ago from another member where they report a buzzing noise in third under hard acceleration, but my noise is a whine, heard under normal driving conditions.
I now suspect having received no replies to my post that this may be an issue I should have researched a bit deeper in the archives first, so will now do so. Regards to all

Hi Broken Turbo,

Welcome to Saabscene!

On earlier 9000's the pinion bearings tended to give way usually affecting fourth and fifth gears IIRC. This gave a noise like a whine that varied with road speed. I had it twice on a 9000i so it doesn't have to be a powerful engine to cause it.
However I can't remember anyone mentioning this to be a cause of third gear problems, but if your right about the car spending a lot of time in third then....

Nick.

Could it just be that 3rd is a bit worn so there is some noise coming from the synchromesh. If is it gear wear then there is not a lot you can do unless you go for a rebuild which is not exactly cheap.

Partial throttle third gear whine is predominant in many 9000 boxes. I've lived with it for over 2 years now and have had 2 gear-crunching torque induced rebuilds... but neither of them has been related to the whine. One was, however, caused by the failure of the circlip that holds 4th gear in place- the main known weakness of the box. It's all down to tolerancing etc. Sometimes adjusting the preload will help.
