2021 toyota tacoma trd off-road rear-end making noise

Because Toyota is always one of the last to convert to “new technology”.

Plus, they don’t have to do any more research. They just threw on the same old stuff that’s “worked” since 95’

 

I'd wonder why the drain plug magnet was missing

 

No telling. It’s either stuck to axle housing or it came out when someone else removed the plug.

 

the noise is really loud but again inly when i press on peddle and depress the pedal but when im moving down highway there is no noise till i release then i press it makes noise again then goes away

 

How is the rear of the truck lifted?

 

Wow!

 

In my limited experience. Rear ends that are failing like to make more noise when “not” under a load.
On the gas, the noise is much quieter. Off the gas it will whine.

I’m not say that’s your problem. But your symptoms seem consistent so far.

 

If the noise is under load, it is a sure bet a bearing is about to fail.

 

I don’t know. OP’s prior post seems to say it happen when both pressing the pedal and releasing pedal?
And some where in between it doesn’t make the noise?

 

that is correct

 

where dose it show him asking if im a mechanic by trade. whats he want to see my certificates lol. i work on big rigs, trash trucks. i did know i was going to be insulted for asking questions.

 

Don’t take the insults too hard. For the most part, the majority of TW is super helpful.

 

What exactly does the noise sound like?

 

So a block lift (hiding behind the exhaust pipe) AND Ride-rite airbags inflated to ~25 lbs

 

I wonder if he is getting really bad axle wrap. Super heavy wheels and tires plus a 6 inch block lift.

 

a grinding noise. at first i thought it was a bearing going out but when i removed tires and spun both bearing i didnt hear a thing. i also spun front of diff to check pinion bearing but no noise

 

I'd worry about getting longer brake lines next after you fix this problem. Impressively poor job the PO did on that lift.

 

are there axle shims under the lift blocks?
