Squeak , thump , rattle ,whine? Does stepping on the brakes or turning have any effect on the noise? Is it a speed related noise (related to wheel speed or enginespeed)Is the tundra 4WD? Questions just to start.
62K miles. did not note change in noise when turning left or right. accelerate from a stop light noise builds as speed builds, quiets some when cruising. becomes more noticeable when decelerating quieting as truck slows PS thanks for your time and expertise! oh it is 4wd I am thinking of buying this truck but this noise has me scared
Do you have a shop that you can bring it to , to have it checked-over before purchase? Common practice nowadays ,so if the current owner objects , then I would decline buying the truck. If the shop looks it over and gives it the 'thumbs-up' except for the rear diff. , if that's the cause of the noise you are hearing, then get an estimate , negotiate sale price and enjoy. It's still a Toyota.(I say that in a good way!)
