    I am the original owner of a 98 PreRunner w/auto and 4cyl engine. I take extremely good care of it as I was a mechanic years ago. A noise became prevelant last winter when the temps began to drop. I tightened the belts(maybe a little more than necessary) but it seemed to work. I think it may have been around the same time the weather began to warm up. Well a year later and it started again. This time I took it directly to my Toyota Dealer who also heard the noise but could not pinpoint where it is from. The noise appears after accelerating to a speed and removing my foot from the gas pedal as the truck is coasting. It sounds similar to a squeak or belt squeal. I also thought it could be a bearing to an under the hood pump, but my dealer said they were fine. On a chance, I lubed my drive shaft and noticed a bearing in the center of the shaft that does not have a lube point. I am thinking this could be the culpret, but I was wondering if anyone else has run into anything similar. My truck has 105,000 miles on it, but like I said, it's my baby and I take exceptionally good care of it.

    Without actually hearing the noise or knowing it's location, I can only guess.

    The bearing you are referring to is the carrier bearing. It could be coming from that, but again it's speculation.

    It could also be a wheel bearing, a u-joint, axle bearing, etc. Is there anyway you can determine it's location?

    It's location seems to elude myself and the two mechanics at the dealership that drove around in it. They said they could hear it on the road, but not while on the lift. In any event, it does not seem easy to pinpoint it only because it would not be safe while driving to find it. And without just "replacing parts" there is no possible way to really know. My dealership has never encountered this in the past nor have they heard this from any other dealers. They had a 20 yr toyota mechanic veteran on it also. It doesn't affect how the truck runs and I'm guessing the noise will either get worse (at which point it can be diagnosed)or go away during the warm season again.

    You could remove the belts and turn you pulleys by hand to see if they have any resistance. They should feel pretty smooth.

    You can check for play in the front wheel bearings by lifting the truck off the ground and grabbing the tires on the top and bottom. Then try to shake them in an alternating fashion (push in on the top while pulling out the bottom). That doesn't always work but it is worth a shot.

    To check the rears you will need to pull the axles and "get dirty".
