Hi All,
So i replaced the Differential fluid with Correct items, but i appear to be still getting a high pitched whine at motorway speeds.
I know its a bit of a 'could be many things' question but anyone have any suggestions ??

Is it definitely the diff ? No chance it could be a wheel bearing ?
Does the whine change depending whether your on or off the accelerator?
Hmmm, i had noticed tbh. Unsure.Quote:

Noises in general though are not easily diagnosed by keyboard.
Mine has a similar noise but it has been there years and i have mentally tuned it out. what sort of a job is it to change the pinion bearing?
Can it be done in position by dropping the propshaft and removing the input flange?
Unfortunately no, pinion bearings replacement would require a full
differential strip down.
