Squealing noise only when cold and on deceleration

So i just bought my 02 limited SR5 with 113k, before i picked it up i had the dealership change the timing belt and wate rpump, and while they were at it, it looks like they changed all the drive line belts too. So i drove it 500 miles back to NY and now when i start it up it makes no noise at all. As soon as i drive and start slowing down, it squeals from about 2k-900 RPM's, and only when decelerating, never while im accelerating. After about 10 minutes of running it stops.... any ideas?

Same here!!! Except mine does it when both cold or hot. Kinda sounds like a cross between jingle bells and cricket, its a squeal/squeak kind of noise. Im thinking belts arent tight enough? Hopefully someone will know what it is...
 
While you tighten your belts check your crank shaft pulley. Mine came loose once and I thought it was just a belt. Turned out to be a damn expensive. $350 for a new crank shaft pulley because the bolt came loose and the $1.95 key that holds the pulley in place sheared off.
 
Mine has been doing that the past few winters. Almost sounds like a break pad wear indicator. - (high pitched metalic chirp/squeak)

Mine is on the front passenger side and stops after I drive a couple miles.

I was hoping mine would go away after doing the Tundra front caliper upgrade.
Also, added new Toytec coilovers in front early last summer but it just started again since we got hit by a cold snap.

It may be the front wheel bearings sqeaking a bit untill they get warm and the grease moves around.

Yea that's exactly it. Weird, it happened to me just a couple days after putting my lift on...mine does it warm or cold, wtf is this thing lol
 
I had Shock bushings make a similar sound on a different vehicle and stopped it by using WD-40 on the bushings.

I know my old shock bushings were dry rotted badly. Mine has done this the last 2 days when I drive home from work. Not as bad as before all the work
but it's still there...
 
How loud is it? Mine does that same thing, I think. Mine is not THAT loud, but I would describe the sound as that of a cricket. My 87 did the same thing, we thought it was the bad transmission, but after I got a new trans it was still there.

Subscribed.
 
Damn it, you know i meant to google that before i posted it.... so i guess that means a limited cant be a sr5.... I'm going to go research it so i know what the hell the SR5 even means.
 
What does SR5 mean anyways ? (Toyota Historical Background)

In the latter part of the 1970's, the SR5 connotation denoted an option code
for the HiLux series of trucks, similar to what the Z71 option code currently
means for an upgraded Chevy or GMC pickup or Tahoe/Yukon. Originally released
around 1975, the 'S' denoted Sport, 'R' denoted the RN motor code, and '5'
denoted the 5-speed transmission. It quickly caught on and the SR5 connotation
passed onto the Corolla and then onto other Toyota car models. Even though the
HiLux name was dropped in 1979 for the United States market, it is still used
today elsewhere in the world as the name for a Tacoma-like pickup and/or the
4Runner, depending on the market.

Note: Some other historical information shows that the Corolla had the "SR5"
designation first, then it was passed on to the HiLux series. The majority of
historical information seems to promote the HiLux first, then the Corolla,
rather than vice-versa.

Today, the SR5 generally denotes a specifc Toyota trim level, with a more
sporty look and wide flexibility for options.

(Thanks to Dianne Whitmire at Carson Toyota as well as ToyotaOffRoad.com for
the historial information.)

(now i see why it was funny, haha) noob!
 
Just a little update on this. I was driving with no music or anything today with it about 35 degrees outside, and raining.

Before I took off from home I let the 4Runner get up to operating temperature. My transmission, even though my 4Runner was warmed up, was still at 55 degrees. I got on the freeway and was toying with the accelerator, listening to my little army of crickets going crazy. Way louder than normal. My transmission read 64 degrees until I exited, where it slowly started climbing. As the temperature rose, the sound started to diminish. Once it hit about 120 degrees, it was gone all together.

What the heck is this noise? I hope with that information someone can help a bit more. I think it's clearly the transmission making it. On the freeway with the trans cold I could hear it while applying throttle, but if I let off the throttle 100% it would get MUCH louder.

Mine is distinctly coming from the front left passenger side. I don't know if I'd call mine a transmission problem. Maybe a wheel bearing..???
 
I cant tell which side mine comes from. I was thinking wheel bearings too, but my brother said wheel bearings make more of a humming sound. If I cant get it figured out I think I'll have to take it to a shop.
 
grease

I had a similar problem not too long ago. sound would come around when i let of the throttle. if you haven't yet. grease your drive shaft. its cheap. it might just fix your problem. if not at least you drive shaft is lubed. good luck
