got same problem with the thread starter except that the speedometer needle does not vibrate and the "tsu.. tsu..tsu noise sa front (mahina lang naman) " is heard at 40 kph and above.

-sabay yung noise sa acceleration, pag mabagal, mabagal din umingay and bumibilis din pag mabilis na.
-already checked for any loose wheelnuts and the tires for any 'bukol' (nag bakasali lang...)
-belts kaya??

plano na pa check sa mechanic pero hingi muna ng inputs sa inyo para di naman magoyo ng kesyo kung anu ano kelangang palitan....

thanks




<<<<<I recently noticed a noise somewhat like "tsu..tsu..tsu..." when my pick-up reaches about 30 kph. Para siyang tunog tren na pabilis ng pabilis as I accelerate. The speedometer needle also somewhat vibrates erratically. Above 40 kph speeds ay wala na. The same is below 30 kph. Walang wiggle sa steering wheel. It happens on paved roads. I already had the underchassis/driveshaft parts greased pero nandoon pa rin. Bago na din transmission/differential gear oil at factory specs. Ano kaya ito? - roydok >>>>
