High pitch hissing sound
05 Odyssey Exl high pitch hissing sound when accelerating fm 37-55 at 2000-2300 rpm n seems coming upfront. Replaced both front bearing n hub assembly n still hearing same. Checked all mechanical, checks good w/ no play. rotated 2 yr old tires, balanced n did alignment n still hearing same. I heard same problem at the back before n replaced bearings n hub assembly n sound disappeared. That’s why I did same to the front. Transmission is really good n never have problem. Any idea, suggestion, experience is much appreciated. |

Hi-Pitch
Car runs n shifts really good, engine so quiet n smooth during idle n w/ no vac leak. Has new serpentine belt. No CEL n only have Ars-Seat belt indicator problem n recently replaced drvr seat belt latch n fixed problem. Transmission never have no problem. Accelerating from 40-55 when high pitch is heard at 2000 rpm. Plan to replace timing belt kits n will continue to check as recommended. Thank you. |
Do you have a cold air intake type air filter? After awhile they become a little dirty and make noise.other than that maybe a vacuum leak. |
High pitch
I replaced all my cars filters with KnN filters n clean them annually when I do oil change, mobil1 15k, annual driving 4-6k. Odyssey 105K, runs really great just worry me this hi-pitch? |
Check to see if you have a retainer clip broken on the brakes |
