I've been told by a few it could be the diff?
Could be the diff. I had a whinny crunchy gearbox on another 106. Changed the oil and that made no difference. Thought it was gonna blow up so I gave it to my brother lol to my amazement, it's still going strong today. Still whines and sounds like it's gonna go bang but it still lives! So you never know, might go on forever like that. I would still change the gearbox oil and look for metal filings etc. Bare in mind though that you seem to get a bit on these boxes anyway and doesn't always mean much, but a good place to start. You can also see how much you've lost from the leak you have. Also you can get Molly slip for gearboxes that makes old gearboxes go on for ever. It's only about £10 so maybe worth a look. Seems to be pretty good at shutting gearboxes up. [emoji6]
