There is TSB on this condition. Go to the NHTSA web site and type in your trucks info then look under the TSB section or ask your Toyota dealer about the Technical service bulletin

Thanks, but I could only find the tsb referring to the differential. My dealership already replace that & it didn't help at all. Was there a different tsb out there?
#7577 of 7624 2005 90K service, Motor Code is 1GR-FE
Nov 09, 2009 (5:48 pm)
I'm getting conflicting information if my 2005 Tacoma needs a timing chain / belt replacement. I've been to several shops and one guy, who seemed to know what he was doing lifted the hood and checked the motor code, 1GR-FE. He told me between 2004 and 2005 there was a motor change, going from belts to chain on the 'timing chain', along with other changes. He mentioned the new engine, 1GR-FE, has a chain, and does not need to be replaced until about 150K miles. I'm wanting to confirm this information in anyone KNOWS. I'd like someone out there that really knows these Tacoma's and has facts about this.
Also, I don't have my service book, can someone outline what should be done at the 90K service? I'm thinking plugs, radiator flush, transmission flush, ...??

Certainly sounds like a bearing. Have you had someone ride in the back while you drive? There's a bearing between the two parts of the drive shaft that might be the culprit (forget what it's called). Also, I'd either escalate, go to a different dealer, or go to a competent, non-Toyota mechanic to see if they can figure it out. You're about to exceed your 60k driveline warranty, so I'd act quickly.

I have a 2000 tacoma just turned 90000.I took it in for service had clutch kit put in, tranny service, rear main seal replaced (since we were there)I changed the oil,cleaned air filter(cold air intake)and radiator flush.Mine also has a timing chain and I too was told not to worry about it til 150,000 or if it was making noises before it needed replaced.

#7581 of 7624 2009 Tacoma deceleration noise? Light deceleration between 55-75 MPH?
Dec 24, 2009 (11:01 pm)
I have searched far and wide to try and find an answer, this is my first post.
I own a 2009 Tacoma reg cab, 4wd, 4 cylinder, manual with 20K miles. At about 10K miles I noticed a harsh howl noise when going between 55-75 mph but only when light deceleration. Like when you just let your foot off the gas on the highway as you are going down hill. A slight apply of the throttle makes the noise go away. Put the transmission in neutral and/or push in the clutch and the noise is stays -- but now throttle position has no effect on the noise. The noise is very noticeable.
The dealer changed the rear fluid to some sort of synthetic-- no change. The dealer refused any further work on the truck since it has has a 2" non-stock lift with slightly larger tires.
I did a 1" diff drop for the front -- no changes.
I added an approx 2 deg axle shim on the rear -- no change.
I replaced the transfer case fluid with purple power 75-90 fluid -- no change.
I relubed all u-joints -- no change.
The next step is to replace transmission lube with purple power lube to see what this effect is -- but I just cannot see this working. I am stumped!!!!
Since the noise stays when in I am in neutral (or clutch in) then I would expect the that the motor and anything associated with motor is not the issue. ie air pump, fan clutch etc.
Since I am not in 4 wd, I can assume that it is not anything associated with the front end. Wheel bearings, wheel alignment, differential, etc.
My only other choice seems there is something in the transmission. I will do the purple power in the tranny to see if there is any change in the noise level or type of sound.
Any suggestions? Any ideas will help. Toyota refuses to help unless I remove all the mods done for the lift. Since nothing is broken, truck drives good, no abnormal sounds under heavy acceleration or deceleration -- it (hopefully) is nothing major.
Not sure if anybody has an answer, but I would appreciate any help. Email me at emberglo2001yahoo.com if you would like. Thanks for all your help.

I would remove the lift kit and let the dealer figure it out under warranty.

#7584 of 7624 Toyota Tacoma Gas Pedal Lubrication

I have heard that the cause of the Gas Pedal stick situation is not caused by floor mats, but rather the type of lubrication used on the gas pedal mechanics. Does anyone know if this is true?
