DIY - Change wiper blade on a budget

So my front wiper blade start squeaking after getting the car for 1 year plus. So I ask around for price to replace the front set wiper, original VW wiper blade will put me back RM190, Bosch replacement RM170 from lelong. I wonder why the high price for a wiper blade? Why cant i just buy something cheap from any accessories shop?

So I went to Jusco to find a wiper blade to mess around. Found one unit 24" for RM8.00 at the car section.

 

Tool:
1. Cheap wiper blade. Length to suit the original.
2. Original wiper blade. Taken from car. 
3. Small screwdriver.

Procedure:

1. Remove original wiper blade from car.
2. Turn the  wiper blade over.
3. Look at the end cap. You will see 2 latch holding the end cap.

4. Use small screwdriver to push these latches.
5. Pull out the end cap.

6. Slide out the original wiper blade rubber.
7. Repeat step 2-6 on the new cheap wiper blade.
8.Compare the rubber profile. It look almost the same. (Right: VW original wiper blade)

 9. Slide in the new wiper blade rubber.
10. Reattach the end cap.
11. Reinstall wiper blade to car.

Conclusion:
1. YES, you can actually take a cheap wiper blade insert and put it in the original VW wiper blade.
2. "You pay peanut, you get monkey". Probably this rubber will not last as long as original. Good reputed brand BOSCH or PIAA will cost some money but not easy to find. VW service center always keep stock.
3. A bit surprised to see rust formation when i removed the end cap. This will be a major factor to replace the whole set.
4. VW uses propriety attachment to attach the wiper blade. It could be the design itself is an Intellectual Property. Anyone who want to use the same design, must get approval from VW or risk legal action. It also reason why BOSCH and PIAA aftermarket wiper blade almost at the same price. Maybe cheaper by RM20-30 only. Compared with generic standard attachment BOSCH wiper blade that will cost 1/3 of a same length by VW wiper blade.
