Toyota Sienna AWD - Rear Viscous Coupler

They were both wrapped in Toyota bags? OEM.

Mr. O, if you’re saying that the dealership will only sell the entire coupler, and dust plate, how were you able to get the OEM bearing, and dust plate?

Great job Mr. O👍 wish you were in CT.?

Can buy the entire differential for around $900. Replaced mine a few months ago and everything is great. Did it in the driveway with a few jack stands. Took about 4 hours.

Does the use of copper anti-seize/lubricating compound help prevent corrosion on threads in aluminum housing with steel bolts? Not sure if i am wording this correctly. I am of the understanding that there is a
corrosive process when steel threaded bolts go into parts made of aluminum. Not sure if the term "Galvanic corrosion" applies to this.

What's the purpose of a vicious coupler

I PDId a ton of these when new in Flagstaff at McCoy Motors toyota/GMC dealership. Toyota told us these were not serviceable or repairable.

The answer is no it doesn’t need to be that tight. Just buff if. A polished surface will slide better and the heat will expand it.
Love watching you have the same struggles I do.

Thanks! Between this and a couple other videos I was able to do this job successfully. Saved me a bundle!

Awesome video. I tried ordering that part bearing from Toyota but they were trying to convince me that its the wrong part. I end up ordering 3 different bearings and will take it to my mechanic and see what works. I sent Toyota this video because they don' see that bearing as a separate part.

i absolutely LOVE folks who will think and do the work,,, for a work around solution! might just be me, but it seems like these car companies are making it harder and more expensive for us, on purpose.

My 11 Venza had that bearing going bad - I bought a replacement off eBay , fit was exact , stopped the roaring , but clutch doesn't engage during wheelspin , just rebuild your OEM , Throw a new pinion seal in while your in there.

It's a crime for Toyota to charge $2000 for that part, and that it went out at 80k miles when these vehicles will go 400k miles or more on the engine. Goodyear wanted to charge me $300 to change a thermostat on my IROC. They said the book says $250 to remove the throttle body assy, and 2 and a half hours labor. I took it home, removed the three bolts for throttle body, and two for the thermostat housing. Took 5 minutes total. 😊

😊how about using the old bearing to install the seal

U vloekt, weet u wel dat dit verschrikkelijk is?

So much for non-serviceable parts Nice Job

great job on junk engineering by toyota

Nice job Eric

How does he not have a huge backlog of cars waiting to be repaired in his parking lot?

If safety was first you would be wearing safety glasses I spent 26 years teaching my students to always wear safety glasses, you have good content good show love your videos say safe

Unit made of Chineseium cost $275-$300. Good ones run over $500. Im guessing Eric rebuilt and installed for probably less than $300. The whole dif which a dealer probably would have dug the owner for run about $900.

👍✊✊✊✊🇬🇧

This guy is great! A lot of knowledge. Good job. Thanks for the video?

How is it, you post a video and shortly after I have to perform a similar repair?

Good work. But don't you think you should have put some silicon on the bearing in place of the O ring to keep water and dirt out.of the housing? Just my observation.

To salvage any adhesive in a tube use the rubber sleeves they sell for such use. Next time, I suggest putting the drive shaft on the assembly and then installing the assembly to the housing. Excellent repair

Good idea marking with your paint marker.
Saves expensive errors.

Concern .. other bearing had an o ring, new one not. Leaks??? Lock tight on new outer bearing surface would seal it .. all be it permanent.

Harbor freight has a great press for 99 bucks I used mine once worth every penny just sayin

Eric O saving the day again!

No grease on seal lip?

Gr8 vid again! 😇👍

Seems the same as a rav4

Thanks so much for this video! I just saved $2900 over the dealership's recommendation to replace the whole unit. Completed the work in about 5 hours. Would have been much faster if i Had a lift. Runs like a dream now.

I had what I thought was a differential noise, like an airplane noise. I did rebuilt the coupler and changed the big bearing and the dust flange, to no avail. The noise persisted so I sold the RAV4 to the dealer, they did not noticed it. So my conclusion is that the cause was somewhere at the front end, maybe the transfer case or the transmission. Who knows…

Metric Bearing number is outside, inside and wide or deep of bearing.
Measure with vernier caliper and look it up in bearing catalogue

Good work mate keep up the good work

Im a 75 yr old retired engineer who has done my own repairs for years. Last Thanksgiving, IBlew my main(120 amp) fuse on my camry trying tocheck out the abs light,before leaving for Oregon . Called dealer to see how much they would charge me since i screwed it up already. Quoted me $360 p&l. Whoa! Thats a lot. Went to p&p and got a replacement fuse out of a junker for $5. Called my mobile mech. to fix it. Took 45min. to fix it. Charged me $80. Saved 275 and didnt have to wait for 2 days or pay for a tow. Dealers are crazy. Who is dumb enough to use them?

Hey Eric another mechanic here but you are on a whole other level truly a master it's a honor to watch you diag and repair awesome bro

Most likely what made that bearing go bad is the crosiotion that was on the outside of the bearing. It's like there is an extra shim or 2 in there putting extra preload on the bearing.

lol. 13yrs in muffler shop...we had a wall of tubes expanded to fit those pesky dust sheilds...worked great as seal drivers too...

Toyota just wants to pull and replace without thinking. More $$$$$$

Everybody it's a 9'er!! 😂 Love this guy

Great video, i like it when you do the unserviceable problem.

Harbor freight has cheap 20t press.
