need opinions please, grinding noise

my truck started making a grinding noise on decel, in reverse or braking. sounds like what you would expect from dirt and pebbles in the rear drum. went out last weekend to the desert for a dirt bike trip and took the truck out for a cruise hit a few puddles nothing special and ove some bumps, also nothing major. heard the noise the next day, came home pulled the drums and nothing all normal im going to take the truck in tonight but i was hoping for some opinions. thanks all...

 

When you hear the noise are you turning or tracking straight?

 

straight or turning makes no difference

 

I hit a large puddle at the beach a couple of weeks ago. Had the same noise! It freaked me out. It sounded like my MTs were rubbing on something then it gradually got lighter. Eventually it will go away.

 

im hoping your right but from how you discribed it it seems different it sounds awful its sounds like when you wear brake pads to the metal .... and then drive another 10000 miles like that

 

My old chevy did that only during decel. and it was the rear diff. ugh!!

 

Mine sounded like an aluminum heat shield was vibrating against metal. I was sure that was it but it wasn't. It happened on a Sat and couldn't take it to the shop till monday. By Monday, it just got softer and went away.

 

thats what im afraid of ive only got 25k on it and i didnt do anything they dont do in commercials haha so im thinking itll be covered but if not.... im @#$^%$%^

 

At least you're covered if it's the diff.

 

+1 hopefully it is something very minor that just sounds horrific and they can fix it quickly.

 

yeah im hoping. ill post the problem when i get word from toyota

 

also the reason I broke mine was due to spending the previous night doing burnouts and popping the clutch. Not to bright in my part I guess

 

^^
I'm assuming still covered under warranty for that one?

 

no warranty

 

oops

 

well it was the heat shield on the drum atleast thats how my service writer discribed it to me im guessing it was the backing plate. not sure how it got bent but it was an easy fix. and warrantied.....life is good. now its time to put something new on it hahah

 

Good deal there!!!
