Noisy transmission

[mechagouki]

Sorry to bombard the board with questions, but I took the truck on the highway for the first time tonight - had the rear seats down as I was loading up the back. Over about 30mph there was a lot of noise from the back of the truck in every gear, it was most noticeable when decelerating in gear, not quite a grinding, but def a sound like dry metal on dry metal, stops as soon as I push the clutch pedal. Truck drives and shifts fine - a little underpowered, but it`s a 22re with 20x,xxx miles on it, so nothing unusual there, was planning on SeaFoaming it tomorrow. It seemed quieter on the way home with a couple hundred pounds of timber in the back - even though the glass was down - go figure.

So, do I have an expensive bill coming my way? Anything else it could be?

Check all your fluids, and don't drive it again until you do, is my suggestion.

I would check the rear diff. fluid. Make sure your pinion gear didn't come loose. Could be a wheel bearing as well.

Maybe you could record the noise so we can better diagnose it.

Yes I agree with them,Check first your fluids and then try it again.

Sounds to me like a worn out carrier bearing to me, my 89 4Runner did the same thing, and would also shake a little at around 60 mp/h when I was going down hill. My 94 Hilux also had the diff start whinning all of a sudden one day, it happens quick. I agree with the others to check the diff oil, and for a few bucks I would change the fluid to see if there is any metal shavings in the oil, and replace the oil with a thicker viscosity, it might quiet it up a little, did for me. And if you need your diff rebuilt East Coast Gear Supply is the place they do great work and back it up. Good Luck

It`s in the shop today for safety inspection anyway, asked my mechanic to check the fluid and refill it with Lucas stabilizer, guess I wait and see.
