Replying to: jim58 (Jun 22, 2007 7:23 am) Hi Jim,   Have been reading all vib problems over again and again. This rev test: Is your 4runner an automatic? I presume it is. These days most are. The interesting comment that I read was the one person that had trany problems and then started having vib problems. I still have a few ideas about this issue.

Replying to: steve146 (Jun 23, 2007 6:10 am) Steve: Yep, it is the 4 speed auto withing locking converter. It is about the smoothest shifting transmission I have ever driven and we have had NO other problems with this vehicle but the vibration. It now has over 50 k miles and still runs great. OH one more problem is the miles per gallon compter. It shows way more mpg than actually getting. Example, at 16.7 mpg, it shows. 20.0 on the computer. I included this in the arbitration also because if a new customer is driving the vehicle and it is showing 16 or so rather than 20, they might not buy it even though 15 to 17 is the rated mileage.

Replying to: jim58 (Jun 25, 2007 7:03 am) Hi Jim,   Well we are narrowing down the difference between mine and yours. I have the 5 speed auto. I wonder if this is a problelm with the 4 speed tranny? My thought is that the torque converter is out of balance. Since you do the rev test in nutral? I'm guessing at this as you did not state the condition which is was being rev ed. My senerio is because with the car in neutral and rev ed up the only 2 things that are a factor in this would be the harmonic balance and the torque converter spinning. Anyhow I hate to see people having problems with toyotas as I own 5 of them with no problems as such. Let me know your thoughts Steve
#136 of 156 4RUNNER VIBRATION FIXES/CAUSES by captneumo Jul 05, 2007 (12:30 am)
HI -   Some updates on vibration fixes -   1) LP_4Runner on http://www.toyota-runner.org/ did the Lexus fix on his 4Runner and feels problem virtually eliminated (ie, 95%). Here is fix -   Parts: 41196–60010 Differential Dynamic Damper (1) - $69.54 91511–80820 Bolt (2) - $1.38 52380–60061 Front Differential Support No. 1 (1) - $143.42 51405–35101 Engine Under Cover Sub–assembly No. 1 (1) - $212.82 45219–60090 Steering Sliding Yoke (1) - $31.65 45203–60120 Steering Intermediate Shaft Sub–assembly No. 2 (1) - $167.27   Labor time was 1-1/2 hours, which he had done free.   2) The Lexus fix TSB is ST3010, which addresses STEERING VIBRATION & DRIVELINE VIBRATION/DRONE. I ran across serveral Lexus owners pushing for this fix.   3) For those wanting to reference the Toyota TSB ST001R-05 SEP 05 Steering - Highway Speed Steering 'Flutter', it is available on the Alldata site, url http://alldata.tsb.com/TSB/60/036007ad.html Interestingly, this bulletin is listed under 2003 Toyota Truck 4 Runner 2WD V8-4.7L (2UZ-FE). I have read it extends to 45 pages, so it may have relevance to your particular truck or might not.   4) There's been a lot of comments on the vibration cause. Expert view on steering vibration does not rule out tires as possible cause. Here is info:   Steering flutter is a condition in which the steering wheel oscillates 5 to 15 times per second in the direction of the turn. It occurs at relatively limited but high speeds between 80 and 120 km/h (50 and 75 mph), and the oscillations on the steering wheel are fairly constant.   Main Causes: • Tire run-out, unevenness, or imbalance • Resonance between the tires and the steering wheel   Flutter is forced upon the steering wheel by the steering system resonating with tire vibrations, which are caused by imbalance, run-out, or unevenness in the tires.   -------------- So all this may explain why some people are getting it worse than others, and the key appears to be to kill the resonance with the steering fix. I have an '05 4Runner Limited with minor vibration, but thanks to all you, can pursue a fix if it worsens with an upcoming tire change.   Hope this helps -   John Replies to this message: koenigbauer (Jul 06, 2007 12:56 pm) rentschl (Jul 31, 2007 12:26 am)

Replying to: captneumo (Jul 05, 2007 12:30 am) To all: I have gone through and read all the postings on this vibration issue. I have a 2002 4Runner, and have the same/similar vibration issue. My steering wheel does vibrate, however the more annoying vibration that is driving me crazy is a vibration of my automatic gear shift. This vibration is not just a "buzz" that is felt, but creates a "rattling sound" of the plastic covering over the gear shift column. Has anyone experienced this same problem? Or have any advice?

Replying to: jokol2 (Sep 07, 2006 7:46 pm) I have a 2003 4wd sr5 v8 4 runner with the same vibration. I currently have 140,000 km and have had the vibration since 110,000 km. I could not believe how many people are having the same problem. After having new tire, rotars, and brake pads, the vibration is still there. It happens at 50-65 mph and seems to be worst when the vechile is hot or on long drives. I love toyota vechiles so much but hate the service dept. so I have been getting it serviced elsewhere. This is my fifth new toyota vechile and I have not had a problem till now. My wife wants a second vechile, it won't be a toyota maybe a GMC.

Replying to: captneumo (Jul 05, 2007 12:30 am) Hi,   I had this issue on an '03 V8 4WD and could never get Toyota to do anything about it. At the time I was pursuing it there was only a TSB for Lexus GX470 but they claimed that that TSB just didn't apply for my vehicle.   Yeah, right...both vehicles share the same frame, engine & powertrain but the TSB was just for the Lexus; thanks Toyota!   I have been able to minimize it by being picky with tire selection and balancing.   My question is now that there is a TSB (at least for the 2WD version), how do you get Toyota to do the upgrade?   -Eric

I have a 96 4Runner 2WD and it has a vibration when I accelterate. When I let off the accleterator it goes away. Is this Transmission or something in the alligenment? Any advice would be helpful.

Replying to: jokol2 (Sep 22, 2006 10:17 am) Toyota 4runner. while driving between 45-70, the contact felt a vibration in the steering wheel. no warning lights were present. I changed all tires. Align and balance are ok. new wires and new sparkplugs were installed before this problem started. 30 days later,the vibration started. please help. jmmstksaol.com Columbia SC Replies to this message: 4runners (Jan 03, 2009 10:32 pm) atarifan49 (Apr 13, 2009 6:39 pm)
