| Check the screws on the SC pulley are tight.
Does the humming only happen when you get on the gas? or when you are just coasting? _________________ '05 GTO 6.0L • 6-spd • 95k miles • 0-60: 4.8s • 16.9 avg MPG • Nelson Ledges Lap: 1:26'95 Celica GT 2.2L • 5-spd • 165k miles • 0-60: yes'98 SC Riviera • 281k miles • 298 HP/370 TQ • 0-60: 5.79s • ET: 13.97 @ 99.28 • 4087 lb • 20.1 avg MPG • Nelson Ledges Lap: 1:30

| The humming starts after 25 -30 mph . then it's a constant. slows as I slow the car. | |

| check your wheel bearings. does the noise go away or get louder during turns?
also take a close look for unusual tire wear. maybe even swap the front and rear tires to see if the noise moves too.
you actually got a shop to install a 3.6 pulley?!? _________________ 1996 with 254k miles, L32 4" FWI -> ported N* -> Ported Gen V w/3.0" Pulley, Stage 3 Phenolic I/C, ZZP FMHE, 1.84 RR, Headers and 3" pipe to mufflers, F-body brakes, and lowered on Eibachs. -RIP AMG C400 White on black.

| to 71stagegs' ? I tried putting into neutral at 65 mph still there. I just noticed my mechanic put on a double sided sc belt . he said the gatorbackbelt I got from intense (gb6-660)was too small. seeing as I have zero exper. with mech stuff I took his word for it. any other possibillity | |

| If you have no change in sound when you let the engine speed down, it's most likely the wheel bearing. Do you have the Trac/ABS light on? | |

| You could put it in neutral at speed, then shut the car off on a straight road. See if the hum goes away with engine off. _________________ '05 GTO 6.0L • 6-spd • 95k miles • 0-60: 4.8s • 16.9 avg MPG • Nelson Ledges Lap: 1:26'95 Celica GT 2.2L • 5-spd • 165k miles • 0-60: yes'98 SC Riviera • 281k miles • 298 HP/370 TQ • 0-60: 5.79s • ET: 13.97 @ 99.28 • 4087 lb • 20.1 avg MPG • Nelson Ledges Lap: 1:30
