2020 4R needle bearing

[bzizzi]

Bought my 2020 TRD ORP W/KDSS new in September 2020, right away I notices the same noise my 2011 had with groining noise in front end that goes away as soon as you engage 4WD. With the 2011 Toyota replaced the front end at 34K mi and the fixed the issue. Took in to service at local Toyota dealer and they said this is normal and most all of them make this noise. Vehicle only has 10K Mi, should I call Toyota customer care or spend the money and have East Coast Gear bushing installed and fix it the right way ? Toyota dealer tried to say it was my tires.
I said then why does noise go away when I engage 4WD. They did not know why.

Did you show them the TSB? I'd make sure they were aware of it and push the issue.

Ditto, but the latest I could find on a search is T-SB-0026-15Rev2. Search for a rev 3 came up dry, rev 2 only covers up to 2017.

if you plan to lift anyways, might be worth going with the ecg bushing. Otherwise, TSB and/or different dealership. Make them drive it and go from 2WD to 4WD, so they directly experience it.

And take a look at this thread, last page, where dealers a fixing later models than 2017

Front Diff Grinding/Groaning Cyclical Noise

Look up this TSB.

T-SB-0012-19
Rev 1 Feb 8, 2019 covers 2016 – 2019 model year 4Runners.
Replace the front differential.

I would't even bother with warranty because new diff will still have trouble prone needle bearing. Order ECGS and replace DIY. It's easy job not much more involved than replacing front half-axle.

Totally agree. I had a 2019, replaced diff under warranty and the issue came back 10K miles later.

Interesting that this TSB indicates a production change implying a fix, but the thread I linked to indicates dealers are replacing diffs on later models, even 2022.*

I think before they were changing them out with a different differential part number .. an actual attempt to fix. Now I believe they are putting in the same part

Mine is being replaced by warranty in the next couple weeks. They are waiting for the part. Hopefully mine lasts

When you talk to them next try to get more details. Like the TSB number they are referencing. And the part number they will install. Thx.

It won't

New casing still have an excessive slop and needle bearing is same design.

True statement, had my (MY19) replaced under the TSB at 15k due to noise. Now at 35k the noise is starting to come back and there is a lot of play with the driver side axle. Just ordered the ECGS bearing and will be installing it this weekend.

 

[JL-2022]

Mine is a 2022 with only 1400 miles on it. They are following the 0012-19 but they said they were told to put in the part based on vin .. so I assume the same style.

Agreed that there are easier ways out, and not much cost, and less hassle, etc ... but I also think they should be held responsible as much as possible. They won't bother to issue fixes if everyone fixes it themselves and they don't hear about it

Just my take. I am not interested or capable of fixing it myself and could use the money on other things

LOL seriously? Do you have a 4in lift and bomb the Baja every weekend? How does that happen.

 

[JL-2022]

Baja? ... pffftttt ... way more exciting than that! Take my kids to school each day and haul my butt to work and ice fishing. About it for the moment

Mine is all stock. As much as I would like a lift and be out playing, it just isn't going to happen. Too many other things more important at this stage.

 

[Forgetful]

That's a bummer it came that way, hopefully the new diff helps. My 21 has 14k miles with a 2in lift, no diff drop and I love going fast on dirt. No issues thus far

ECGS bushing

So, does the ECGS bushing make this better because the bore that the needle bearing sits in is actually oversize? For the life of me, I cant figure out how a bushing is so much better than a rolling element.
