20-02-2023	Liqui moly engine flush and shell helix h7 5w-30	First time doing this using liqui moly engine flush and replace the engine oil with shell helix h7 5w-30. It does make a different the engine feeling lighter. But tapping sound still linger.  Shell Helix will be used as flusher for the liqui moly to wash away the remaining remnant of the liqui moly engine flush. One week and then replace with perodua engine oil again. Alza engine flush with liqui moly engine flush and shell helix h7 5w-30
21-02-2023	Replaced stabilizer link left / right	The car stability greatly improved. The wornout ball joint of the original stabilizer link lasted for 12 years has gone bad. When cornering and moving on uneven road the car feel wobbly. After replacement its very stable. Replace alza stabilizer link

After 12 years of using Perodua Semi Synthetic Gold by chance the shell helix promotion given the opportunity to try. The fuel economy of the car significantly improved after 12 years of researching and thinking - after all, the engine oil made the difference. Next Oil Change 6 Month from this date or 10,000km (140,347km)
11-03-2023	Replaced front left (passenger side) control arm (lower arm)	It fixed the wobbly tires and also fixed the crackling sound of cv axle joint inside the gearbox. This is very interesting finding that the left side (passenger side) gearbox drive shaft carrier is meant to be loose. Now the problem is when the wheel side suspension components gone bad such as control arm, stabilizer link, tie rod end, knuckle spline thread loose, rack end - these component can affect the gearbox side of the driveshaft and making it more lose as a result it generate crackling sound like in this video cv axle gearbox bearing noise.  Replacement of the lower arm fixed the following 1. Squeaking noise of the absorber 2. Crackling noise of driveshaft inside gearbox 3. Fixed wobbly tires
