Helicopter Sound at 40-50km/hr

[tonyboy]

ask ko lang mga sirs, my car has some sort of "helicopter" sound galing sa harap lalo na pag around 40-50km/hr ang takbo. same case din pag naka neutral at 40-50km/hr and takbo.no noise naman when turning left or right. pina wheel balance ko na and alignment pero same pa rin. brought it sa 2 talyer to have the wheel bearings checked, ok naman daw. tire related na kaya? any ideas? TIA

Check your tyre wear.

Sabihin ko sana wheel bearing kasi ganyan yung sa FD namin just a few months back, parang may muffler nga. :-) Pero since ok, tire wear mo ang next na icheck mo as said my LSB.

could be the tyre has internal defect, baka napunit at naghiwalay na yung thread sa outer rubber. DELIKADO YAN, HIGH SPEED FRONT TYRE BLOWOUT. pagpalitin mo yung front tyres and rear tyres. kung lumipat ang sound sa likod then yun na yun, internal defect ng goma. kaya may helicopter sound kasi nagcla-clap yung 2 separated rubber parts.

thanks mga sir. i'll check the tires and have them rotated para ma isolate din mabuti.

or use your spare tyre. pag nawala then the tyre you remove is defective.

kakagaling lang sa talyer kanina, the mechanic did a thorough inspection of the wheels and the tires. ni lifter yung car then pinaandar to check where the noise was coming from. sabi ni mechanic front wheel bearings daw ang culprit since ok naman daw yung tires and wheels. question ko is advisable ba to repack or replace na yung front wheel bearings? may nabsa rin kasi ako na pag sealed type daw hindi na pwedeng irepack? my car is a honda city 2004.

replace na lang.

update: front wheel bearings replaced; alignment, balance and rotation done. unfotunately the humming helicopter sound is still there. also kanina medyo na may slight vibration din sa steering wheel na nasabay sa humming sound. help please. running out of ideas and budget.

Sana yun bearing na binili mo binalik mo nalang para refund kasi mali naman mekaniko mo eh.

Yun wiggle balancing lang siguro
