| Purchased a 2004 toyota 4 runner. noticed wobble or vibrations in steering wheel when accelerating and at speeds around 70-75 mph. took in for maintenance, technician balanced tires. still had problem so took it back in resulting in a road force balance and new set of tires. still have mild vibration. *jb | |||

| Annoying engine or drive train vibration between 1400 and 2000 rpm. more noticeable on upgrades. releasing accelerator pedal results in eliminating the vibration as the engine speed decreases. the vehicle is a 2004 toyota 4 runner v8 limited. this issue was initially noticed at about 700 miles on the odometer. *cb | |||

| 08/01/2004 | 200 | 1 | 07/15/2004 |
| Resonance through steering wheel during light to heavy acceleration when trans was shifting. dealer, at this time says it is a characteristic of this vehicle. 1000's rpms and up sometimes worse then others. *jb | |||

| My 2004 toyota v8 4wd sr5 4runner was bought brand new in feb/2004. at speed 71-73 mph, it generates annoying harmonic humming noise from transmission and/or driveline. the noise is more noticeable in cold weather than in hot one. it become less noticeable at speed above 78 mph. a toyota dealer mechanic test drove the car and confirmed the noise, but offered no help to fix the problem because they do not know how to. *ak | |||

| 2004 sr5 v6 4wd experiences droning vibration or rumbling on floor, pedals, and steering wheel when car is driven between 1500-2000 rpm. vibrations are significantly worse for ambient temperatures below 35 degrees f. and very bad below 15 degrees f. also becomes more predominant during acceleration. vibration dissappears when transmission is shifted into neutral at same speed. appears problem is in drive train/transaxel and not transmission. *ak | |||

| 12/21/2003 | 1 | 1 | 12/15/2003 |
| I own an 2004 toyota 4runner sport with the v8/awd. took it on a long road trip over x-mas and noticed at exactly 71mph you start to hear a cyclical noise (about 2-3 per second) that increases in frequency as vehicle speed climbs. no vibration in steering wheel or pedals. but both driver and passenger feel it in floorboards and hear it. disappears at 82 - 85 or so, and as soon as foot is removed from the gas pedal. dealer claims no known issues and offers no solution. *ak | |||

| 01/10/2004 | 100 | 1 | 01/02/2004 |
| While driving vibration came from the drivetrain/front differential at various speeds. seemed to be related to rpm and outside temperature. most prominent at @2000 rpms, and below 50 degrees. vibration felt in pedals, floor and steering. heard throughout the vehicle. dealer tech trying, but no answers. *ak | |||
