Guys help on this problem of mine. got this unusual sound tick...tick..near aircon and alternator area no pattern of sound..
What I did was:
1. I replace the idler bearings with part # 6301du ball bearings 2pcs two idlers
2. Pulley Bearing of aircon with part # 35BD4820DUM6

Not replaced is the:
Tensioner bearing and alternator bearing


Test with no load, i mean removed the belt and start the engine and there is no tick..tick.. sound.....so confirmed that its on the load side not in the engine where the unusual sound is.

[B]Question Guys is it possible to replace the alternator bearing?[/B]
