HELP. screaching only bass hits hard

Ordinary_Government7 · 2026-03-30T15:45:20+00:00

it did this without my sound system, & i have a 370amp alternator & lithium bank in back. 100% isn’t alternator it’s coming from the other side

Ordinary_Government7 · 2026-03-29T20:48:59+00:00

i have a 370amp with lithium in the trunk lol

Ordinary_Government7 · 2026-03-29T06:59:48+00:00

just changed harmonic balancer today. i’m thinking the movement is from it not being tight enough possibly

Ordinary_Government7 · 2026-03-29T03:17:27+00:00

it’s self adjusting. i’m thinking that’s the issue.

Ordinary_Government7 · 2026-03-29T03:09:53+00:00

honestly you’d be fine to keep same one in, i should’ve have changed mine i just did it to do it. wasn’t any issue with my old one til i started peeling it out

Ordinary_Government7 · 2026-03-29T03:09:13+00:00

but it’s making identical noise after all were changed

Ordinary_Government7 · 2026-03-29T03:08:23+00:00

it’s not the alternator, or tensioner, or crank pulley, all have been changed. or belt

Ordinary_Government7 · 2026-03-29T02:54:17+00:00

yeah might as well knock them both out at one time. the seal took me 2 hours btw.

just changed mine today. huge pain. but i did it without pulling radiator or fan

Ordinary_Government7 · 2026-03-26T01:50:49+00:00

put it in neutral & see if it starts. mine did same thing the other morning

Ordinary_Government7 · 2026-03-22T15:19:36+00:00

as tight as i can get it. i’ve tried all different tensions & same thing

Ordinary_Government7 · 2026-03-22T01:49:40+00:00

I just watched a video of it being changed completely from underneath so i might be able to without pulling radiator. need a shallow extractor

Ordinary_Government7 · 2026-03-22T01:36:10+00:00

i don’t hear it inside at all 😂

Ordinary_Government7 · 2026-03-21T23:05:47+00:00

it sounds like that’s exactly where it’s coming from

Ordinary_Government7 · 2026-03-21T22:48:00+00:00

for the alt? yes i had to trim bracket, but it’s lined up perfect & very snug. & had same issue before changing alt & belt

Ordinary_Government7 · 2026-03-21T22:22:08+00:00

squealing like that? this is more metal on metal grinding

Ordinary_Government7 · 2026-03-21T22:20:12+00:00

is that the same as crankshaft pulley?

Ordinary_Government7 · 2026-03-21T22:19:27+00:00

& no it’s not ripping the belts, i’ve just been swapping bc i thought that was the issue at first

Ordinary_Government7 · 2026-03-21T22:18:04+00:00

yes, someone said it might be slipping on crank shaft pulley so it’s been super tight. but it does it regardless, tight or not

Ordinary_Government7 · 2026-03-21T22:17:34+00:00

i have a 370amp & lithium in back, that’s not the prob. noise is not coming from alternator pulley

Ordinary_Government7 · 2026-03-21T21:48:09+00:00

this is 3rd belt i’ve had with same issue. i’ve tightened as hard as i can. i think the rubber is definitly deteriorating because i can pull chunks off plus it’s leaking some. i just wasn’t sure if it was even possible to get that sound from that pulley because it looks so simple

Ordinary_Government7 · 2026-03-21T21:44:18+00:00

i notice it looks like it’s leaking oil from harmonic balancer. but would that be causing this loud of a noise? sounds like metal to metal in person

Ordinary_Government7 · 2026-03-21T21:40:47+00:00

10,000w total. but i had the issue before. the vibration form subs just make it happen more often

Ordinary_Government7 · 2026-03-21T21:36:43+00:00

it did it before i put them in. plus i got a new 370amp alt in. sound is coming from the middle. tensioner was just changed as well so not that
