Dead stock 2019 Tacoma Limited: Needle bearing/front diff noise

When he lifted the truck the rear suspension went to full droop, this increased the angle of the rear drive shaft moving the center bearing, the bearing didnt make any noise in this new position until it worked its way back to its other position. Have them check the center bearing.

 

Will do. Thank you!

 

Have you tried rotating, or better yet, swapping wheel/tires off another truck?
I am not real hopeful, but sometimes a bad tire does weird things, and it would be nice to eliminate the easy and obvious, before you start randomly swapping out driveline components.

 

Drive it until it gets really bad or fails and it will be easy to diagnose. You have a long warranty.

 

Actually, based on mileage, the 3 year/36,000 miles warranty is long in my past. Since my Taco has just over the 64K, I'm even outside the 5 year/60K drivetrain warranty. Maybe Toyota will be nice and help me out, but we'll see. That's why I want to figure this out before something more significant breaks. I do have an extended warranty so I'll see if that coverage is worth the money paid.

 

PROBLEM SOLVED!

I leased my truck for three years, then bought it in March of this year. With frustrating supply chain vehicle shortages, the resulting increase in used car values, and how much I enjoy my truck, it was an easy decision to stick with my 2019 Tacoma 4WD Limited. Buying it for the residual value established in 2019 put me in an equity position the moment I purchased it in 2022.

At the time, I was reluctant to include an extended warranty/service contract because my Tacoma had been SO RELIABLE. Would $2,500 for the top-of-the-line service contract really be worth it? Well, the gentleman who leased and then sold the vehicle to me has been a friend for 38 years. My wife, two sons, and I have acquired all of our vehicles from him for years. He's honest and I decided to go with his recommendation.

Jump ahead to September/October 2022... a few weeks after posting this thread and wondering what was causing the roaring sound under acceleration, my Tacoma now has a new transmission and torque converter. The extended service contract paid for parts and labor, less a $200 deductible. No more noise and my truck runs great again. The local dealer worked with the warranty company and, aside from taking a few days, it was easy.

Yes, the $2,500 up front cost, plus a $200 deductable was worth it.

Also: Credit to the dealer technician who kept searching for the source of the noise. He was great to avoid firing the "parts cannon" at the truck. He spent hours applying those electronic "ears" around the front differential, center bearing, heat shields... then, the bell housing... and finally reported that he had found the source fo the noise: torque converter/transmission.

 

If you have not already, you need to install a spacer kit to drop your differential so that your CV axles are more in line with your wheels after you put a lift on your truck. I did not read this entire thread so if this is already been addressed, I apologize I hope this helps. Should stop the noise.https://www.extremeterrain.com/supr...3f3f76caaf92cc2&gclsrc=3p.ds#4577129471723818

 

There is no lift kit on the truck. It's "dead stock". The issue was resolved in October. The transmission was replaced.
