🔧 MOT FAIL → REPAIR → PASS ✅

Another MOT repair job to share.

This vehicle failed its MOT due to an issue with the offside front CV joint boot. The CV joint itself was not damaged — the problem was caused by a cable tie being used by a previous repairer to secure the CV boot.

Although a cable tie may look like it is holding the boot in place, the CV boot is constantly rotating at high speed with the driveshaft and also has to flex during steering and suspension movement. A standard cable tie cannot maintain the correct and even clamping force, and eventually it had come loose, leaving the CV boot loose/insecure.

MOT failure:

❌ Offside front CV joint boot split or insecure – Major defect

We don't believe in just putting another cable tie on it and calling it a repair 😆

🔧 Removed the old cable tie
🔧 Inspected the CV boot and CV joint
🔧 Cleaned and re-greased the joint
🔧 Fitted the correct metal CV boot clamp
🔧 Used the proper tool to evenly tighten and secure the clamp
🔧 Checked the boot for correct operation during rotation and steering movement

Done properly, rather than just securing it with another cable tie and hoping for the best. 💪

Repair completed and vehicle passed its MOT ✅
🔧 MOT FAIL → REPAIR → PASS ✅

=============================================

又到 MOT 實戰分享。

今次架車 MOT Fail，問題其實唔係 CV joint 壞，而係 上手維修時用咗索帶固定 CV boot。

索帶表面睇落似固定到，但 CV boot 本身會隨住半軸不停高速轉動，而且 boot 仲會有屈曲、轉向嘅動作，普通索帶始終唔能夠好好保持均勻而足夠嘅夾力，結果索帶甩咗，令 CV boot 變得 loose / insecure。

MOT 判定：

❌ Offside front CV joint boot split or insecure – Major defect

我哋就唔再用索帶「頂住算數」😆

🔧 拆除舊索帶
🔧 檢查 CV boot 及 CV joint
🔧 清潔及重新處理 grease
🔧 使用正確 metal CV boot clamp
🔧 用專用工具均勻收緊，確保 boot 正確密封及固定
🔧 最後檢查高速轉動及轉向時 boot 運作正常

跟返正確方法做好，唔係求其綁返條索帶就算。 💪

修理完成後重新 MOT，PASS ✅
