I had 2002 Perodua Kelisa with millage over 200k km. A few month ago I change the rear spring since my old spring doesn't work perfectly. I change new one with the brand APM. But the problem come after I change the spring. A strange noise come up whenever I drive over bumpy road/ uneven surface. The sound come from the rear left tyre. It sound like something loose (kinda of screw or bearing loose...). I send the car to several workshop but none of mechanics could fixed it. Also to mention here, my rear left tyre is different with the rear right one. Is it the problem because of the tyre or spring??
