Classic Mini Diff Rebuild FAIL… £300 Mistake! 😭

In this video, I take on the job of rebuilding the differential on my Classic Mini gearbox… and what should have been a straightforward refresh turns into an absolute nightmare 😬 We start by stripping and rebuilding the diff with new planet gears, thrust washers, bearings, and a competition diff pin – keeping things mostly standard but future-proofing for increased power. Everything is going smoothly… until disaster strikes. 💥 A bolt suddenly loses torque… 💥 Threads rip clean out of the diff cage… 💥 And what should’ve been a simple rebuild turns into a full-blown rebuild AGAIN. After sourcing a replacement cage (huge thanks to Paul Jefferies 🙌), things go from bad… to worse… with bearing fit issues forcing a rethink. In the end, I bite the bullet and upgrade to a brand new cross pin differential – an unexpected £300 hit 💸 But was it worth it? 📩 Contact & Links Thomas Classic & Modern https://youtu.be/siXq9G2uBFY?si=TFYJTBKr2ubSGvNP 📧 E-mail: [email protected] 🛒 CMW Online Store: https://logothatpolo.co.uk/store/cmws/ ☕ Buy Me a Coffee Want to offer a quick thank you?
