#12 of 490 Tundra Engine Knocking and squeak in the rear
Nov 10, 2003 (5:24 pm)
In response to yro message. I own a 2001 Tundra with 38,000 miles and I have used regular unleaded gas since I bought it and now I have been noticing some light knocking at low speeds (up to 45 mph). At higher speeds I do not notice it. Was going to call Toyota but will probably get the response you did; use a higher grade of gas. I will change grades of gas to see if it stops it. Also that rear squeaking noise I had checked and the Toyota service guy where I bring my truck for service said it was nothing. I have not noticed it lately. I will post another message if I find anything else different than changing gas for the knocking noise from my dealership.

I have a 01 tundra with 43k. I have developed a vibration at speeds above 35 miles per hour. Have new Goodyear Eagle tires. The vibration seems to only be in the left front. Have had tires checked for balance-out-of-round, rotated, wheels checked for out-of-round! Have had another person say he has the same problem but above 60 miles hour. Anyone have this problem? (Dealer has no clue, but will be glad to look $70.00 hr.

I am addressing the problem with the vibration.If you don't have Factory tires this Problem can exist.I also know that you will get a clicking or clanging noise at times that is the ABS Actuater.This sounds like its coming from the rear, and is normal. This is normally heard after starting the Truck and when you first get over 6 mph. This noise may sound different to different people.I will talk about not using Factory installed Tires later.

If you just got new tires and you did not experience this vibration problem before, most likely you have a bad tire or even more likely they balanced them wrong. And balanced them wrong second time and third time around. I would not believe that this is possible, but I have experienced this myself with my Nissan pickup where the only problem was systematic incompetence of the people balancing the tires. Try somebody else - also some Toyota wheels require special flange adaptors to balance properly.
There can obviously be other sources of vibration - but tires are always the prime suspect. Quality of many tires nowadays is questionable, and this is why I stick with Michelins. I got 78K troublefree miles (after I finally found a place that balanced them properly) out of a set of Michelin LTX M/S on my Nissan 4X4.
#16 of 490 2003 Tundra RPM Hang-up - Safety Issue
Nov 22, 2003 (9:20 am)
I have a 2003 3.4, V6, 4x4, 5 speed. While traveling at highway speeds, if I have to brake hard the RPM's are delayed for up to 1.5 seconds before the idle starts to drop. This occurs with and without cruise control being on.
I'd like to also note that my last truck was a T-100 with the 3.4 V6 engine - so I am very familiar with how this engine should respond.
Dealer claims this a computer problem and Toyota has not issued a TSB yet. Dealer also claims that this feature was added to reduce jerky feeling when shifting gears. (Heaven forbid people with Manual transmissions learn how to shift).
The problem is a serious safety issue. When traveling at highway speeds, in an emergency, you can't afford to loose 1.5 secords of braking time.
Additionally there is the added wear on your front disk brake pads due to the engine trying to maintain RPM while brakes are trying to stop the truck.
If anyone has noticed this problem please notify your dealer and this list. To check your truck, next time you're cruising at 55 or 65 mph, note the RPM - then if you have to brake hard try to note if the RPM drops immediately or, hangs up for a second or two. Another way to check this is, while parked, race engine to 2500-3000 RPM then switch foot from gas to brake pedal as fast as possible. Note the RPM and engine sound. You will find the engine still maintaining that 2500-3000 RPM.
Also, Dealer pointed out that unless there are more complaints, Toyota 'will not' do anything about this problem.

Thanks to all

I recently had a T-100 that developed problems with GoodYear Tires - everything was checked, even tires were replaced but did not cure the problem. Interestingly enough - the only thing htat had changed was the TIRES!! My advice - Get GoodYear involved...Hope this helps

Mine is a 2002 and I have the captain chairs.
Have you tried adjusting the seat bottoms to a different position? Also recheck seat back position...this can make a world of difference in comfort...

I owned a T-100 with the 3.4 V6 engine. Periodically (once a month), I filled up with Premium gas (91+ octane)... Never had a knock problem....also keeps injectors clean...Try a couple of tanks and see if that helps......

My '95 Tacoma didn't do well with the 87 octane fuel the owners manual recomended. I ran it on 89 most of the time.It pinged a little on 87 and had noticably less power when towing 4500 lb.

We have a 2000 Tundra that vibrates when you brake going down a hill. Still under warranty. Took it to the dealership & told them the rotors needed turning. They said the brakes would need cleaning also. We have heard them tell other people this & charge them quite a bit for it. My husband asked them if their was a warranty on it, since they would get dirty again the minute we drove off & applied the brakes. Has anyone heard of it being necessary to "clean the brakes"? Sounds like a scam to us.
