Variants covered
Wiper size depends on the windscreen, not the trim, engine or fuel – every variant of a generation takes the same blades:
- MU-X (2017–2021): 4x2, 4x4
How to replace MU-X wiper blades
- Lift the wiper arm away from the windscreen until it locks upright.
- Press the release tab on the U-hook adapter and slide the old blade down off the hook.
- Slide the new blade onto the hook until it clicks into place.
- Lower the arm gently and repeat on the other side with the correct length.
- Test with washer fluid – the glass should be clear in one sweep.
When to replace
Every 6–12 months, or sooner if the blades streak, squeak, judder or leave unwiped patches – especially before the monsoon.
