they will ask you change both sides, but u can change one. terus terang the PC screen show one side out of alignment.
so i told them only one side need to adjust. dun try to sell me something i dont need.

yup , learn to read the figures like camber, castor etc, on the monitor screen. its display clearly infront of the car for the worker to see

wah skimming long time no do liao.. forgot price, i think below rm100 one piece.. (maybe 60-80) depend on shop wan

alignment..can check from tire condition, it can tell you if it makan side or tengah..due to alignment or camber problem..
really got to rely on honest tire shop to check on it first.

Normally i do allignment every 6 months once or about 10k km. Then do tyre rotation as well.
Camber screw original ones are very thick and strong. Only if you kena accident or pot hole until tyre burst or rim bent, and damage it, then you have to inspect for damage. If not, i wont bother replacing the camber screw at all.
I did brake disc skim for RM80 per piece, not per pair in Klang Valley. Myanmar guy come do for me.
