Question about Toyota Sienna

Open Question

I have a 2004 Toyota Sienna AWD Minvan that just started making some strange noises today. When I step on the gas pedal from a complete stop, it makes a quick squealing noise (kind of like nails on a chalkboard) and then the sound goes away as I accelerate. It sounds like it's coming from the rear. This only happens in drive, not when it's in reverse or even when I rev the gas while idling. Secondly, I noticed a faint knock whenever I move the car from park to neutral. No sound from neutral to drive, drive to neutral or neutral to park. Lastly, I noticed that if i try to accelerate quickly (say when getting on a highway ramp) sometimes there's a noise from the front that sounds like marbles rattling in a jar, but the noise disappears once the gears shift. Any input would be greatly appreciated.

SOURCE: 1996 suburban makes grinding noise in 2 wheel drive

sounds like the clip on the rear output shaft its probably broke. do this by removing the rear driveshaft, and the tail of the transfer case, there are 4 bolts holding it in place. then grab the output shaft and see if it has any front to back movement. if so pull it all the way to the rear and you should see a groove at the front part of the shaft where the clip goes. Then you should find the pieces fo the clip in the tail housing. One person said he found the replacement clip at a local tranny shop. I am calling the dealership parts counter for a new clip for my 97 Tahoe tomorrow. Hope this helps..

SOURCE: 1991 Caprice No reverse. Moves in neutral. All forward gears OK.

What engine? Rear wheel drive ?Sounds like shift linkage or cable out of adjustment slightly. Have a look at where cable or rod attaches to transmission for adjustment. If not sure of what your looking for get back to me with info.

SOURCE: Harsh grinding noise while in gear and car won't drive!

Had the exact same thing in my 93 and it was the CV Axles - they have a C clip that hold them in place - sometimes the C clip and fail; sometimes you simply have to replace the CV Axles - much cheaper then a tranny; a good suspension shop should be able to diagnos w/o it costing you an arm and a leg.

Brakes are making loud grinding noise when slowing down to stop or on an incline


Ok, it could be a few things, 1. bad break caliper. 2. if you have ceramic breaks, it could be a cracked brake pad, and if they are not ceramic they can still be cracked. 3. if you drive a lot then it could be that you need new breaks again.. 4. also have your back breaks checked along with the front ones..
