Guys, do you have any idea within Metro Manila na nag-aayos ng kalampag?

Already tried Zafra last year pero may kalampag parin sa seats and yung door panel may rattle kapag medyo malakas yung volume.

Here are some info:
-Tire pressure are maintained every week
-Rear shocks was changed last November and Front shocks are planned to be changed kapag PMS.
-3rd row seats are not folded up
-Nilagyan ng bushing lahat ng pwedeng lagyan para lang tumahimik.
-Naka-leatherette seats which may cause the "kalampag sound" but I think yung mga bakal sa ilalim ng seats yung kumakalampag which I can't find out saan mismo galing
-Naka-aftermarket speakers which may cause rattle sa panel but already changed almost all the clips but the rattling sound is still there.

In short, if may kilala kayong know-it-all mechanic when it comes sa kalampag, please let me know para matapos na yung problema. Kasi habang patagal ng patagal mas nakakainis yung sound na nagegenerate ng kalampag

Lumalabas tuloy na mas maingay i-drive yung "newer" Innova na gamit ko sa luma namin.

Thanks in advance for the replies.
