    I've got an 03 Sequoia (same interior as 04-06 DC tundra) that has a very irritating rattle that happens when driving between 1600 rpm and 2000 rpm. It sounds like a high pitched, tinny, almost audio feedback kind of sound. It seems to be coming from inside the dash behind the radio. Any...

    Single owner, 2003 SR5, 4.7L, 2UZ-FE with 220k miles. Truck has never once been in the shop or on back of a tow truck. While coming home from work, I noticed that the stock oil pressure gauge bottomed out suddenly and I heard a faint “ticking” sound, appearing to come from the passenger side of...

    Good morning all, I wanted to introduce myself and post images of my recently acquired 2003 SR5. I have been in need of a 4X4/Towing vehicle for a while. New Mexico has tons of outdoor space, and for the most part my Honda Fit can get the job done on camping. That is if you can access...

    Does the front drive shaft rotate when NOT in four wheel drive? Also, can the front drive shaft be removed and still be able to drive the truck without it? I have a very unique humming noise coming from what I believe is the front end, but it is very random. It has been there off and on for...

    Hey gang, I am relatively new to the forum though I've been reading a ton here. I am having an issue with a suspension lift I just did and was hoping that you could help. Here's my scenario: I have a 2003 Tundra AC with 175k. I bought the truck at 125k with a leveling kit up front. It had...

    I stopped at Autozone to have my check engine light checked and came up as leak in emission evaporator system. Where do I start with that? It runs great but im wondering if I'll get better performance and mileage if it's fixed.

    I have a 2003 tundra with an O2 sensor problem. The old O2 sensor was coming up with an error code “heater circuit low” P0031. When I replaced it the truck generated a new error code Sensor Circuit Low Voltage. The new error code on come on after a few days. I have checked for vacuum leaks and...

    I have an 03 4.7 Tundra 4 speed, 120k miles. I'm thinking about swapping a 5 speed automatic from an 05-06 into my 03. I've done alot of searching and couldn't find very much information about it. I do know that the 5 speed has better gear ratios, especially 1st to 2nd, and is more efficient...

    I just purchased a 2003 Tundra (Limited). I'm looking for tire suggestions. Truck use will include a lighter (900 lb) pop up camper, some long highway travel, and some back road four wheel drive use. thanks

    I just bought a 2003 Tundra. Love the truck with one possible concern. The rear end of the truck seems to stutter or slip sometimes when starting from the dead stop. Are there any known issues with the transmission that might cause this condition? thanks

    I had difficulty finding all of this in one place, so I thought I would share the wealth. I did not take any pics as of yet. I have to install the steering wheel controls and rear cam, so I will post some tomorrow. -VSS wire = Green with orange stripe: behind the instrument cluster -Reverse...

    Due to the amount of winter weather we had this winter I used my truck's 4 WD option a lot. I soon found that while in 4 WD the truck would balk at reversing on an incline. On a flat surface it was fine. Any suggestions? Thanks!

    I have a 2003 tundra with about 98k miles on it. Just recently my check engine light came on and my air conditioner does not seem to be cold. I was wondering what this might be and I thought I would just go ahead and ask before I put her in the shop. Anyone have any ideas or thoughts as to what...

    Does anyone who installed the 00-02 PA body lift on their 2003 tundra have any specs on how they extended the gas filler neck? The pipe that comes in the kit does not fit exactly. This is something that I really do not want to screw up so if you have any ideas please express them. Also I want to...

    Just recently, i installed a 00-02 3'' body lift on my 2003 tundra stepside. Everything in the kit worked except the rear bumper brackets. I was wondering if anyone out there was able to make something work as to raising their rear bumper so that there was not that 3'' gap between the tailgate...
