Non-failed e-torque?

[DanAR]

New to me 24 Laramie with 56k miles, no issues so far. I did recently change both bearings in the MGU as preventative maintenance due to a slight to moderate bearing noise during operation. Rear bearing was a little noisy but had not failed. Front bearing was in good shape but replaced it anyways. Both tensioners replaced first, noise was still present so off with the MGU. Now, quite as a mouse and charging perfectly.

I’ll chime in too. Can you give us some insight on how you did this, particularly the source and part numbers for the bearings? Thanks.

Etorque is covered under 8 year 80k mile warranty I believe. Dealer won't do anything w/o a code so decided to change out the bearings with a competent assistant. Part #'s used both Timken bearings.

Used one of these to remove the pulley. Came off easier than expected.

Watch this video a couple times and went for it. Enjoying some adult beverages, took us 3-4 hours to remove, rebuild and reinstall.

Breaking the unit apart was done with a rubber mallet. Removing the original bearings with a press and appropriate size socket was straightforward. Used some soft pine 2x4 as a base to press out bearings as the MGU unit is made from aluminum and has large fins instead of a flat base to press against. Rear bearing (small one) was the culprit and easier to remove than the front (larger) one. Both were fairly easy to remove.

Did not take any photos, too busy focusing on task at hand and keeping the beer cold but so glad we did this, MGU is quiet and working like designed. It is easier than replacing manifolds, thats for sure.

Sweet, thanks for the info !

Was your competent assistant one of the kids holding a flashlight, feeding ya cold ones and fetching the 10mm’s?

Excellent, thanks very much for the post. I have about 7 large tool chest stuffed full but that puller is one I don’t have so I guess I’ll have to get one to have on standby.

As with all forums, especially vehicle related ones, you mainly read about all the issues and failures about the particular product.

After reading online it seems with the e-torque its not just IF it will have an issue, but WHEN. Has anybody with the e-torque NOT had any issues?

If you have had an e-torque truck for a while and not had any issues, post up the year and mileage of the truck. Im super curious. Is there such a thing?!

Hi. I have a 2020 Ram 1500 with 23k miles on it. (Bought new in Jan 2021) No issues thank goodness. It will likely take me another 5 or 6 years to get to 50,000 miles -- which is when I've read that the likelihood of an E-Torque issue increases significantly. Getting to 50,000 miles will occur sometime around the year 2031. That is good because it gives me a lot of time - hopefully trouble free, but bad because the 8 year MGU warranty coverage will be over in 2029. Hopefully by 2031 the E-Torque related parts availability issues will be solved.
Thanks. - John

It is not a time bomb. You could be in an explosive car crash anytime between now and 2031. Basically, to long a time to even start worrying about something like that.

An auto start stop eliminator is probably the best preventative method you can take. Unless you have trained yourself to turn off every time you crank the truck.

Hi. I'm not understanding how an auto start/stop eliminator will prevent issues. The pulley and bearings are turning any time the engine is running, and the bearings in the MGU are one of the primary fail points. I've not yet heard that the simple task of starting the engine (autostart) causes any significant stress ... have you?
Thanks.

[DanAR]

It doesn’t. The truck is still charging off the MGU into the 48V battery which is charging the 12V battery through an inverter. Do the stop/start eliminators also eliminate all the other MGU tasks, smoothing out shifts, brief torque bursts on heavy throttle demand, regenerative braking, etc?

 

[TC]

Just my opinion..Each time the MGU has to start the engine, the bearings amongst other items are stressed and wear occurs. After thousands of these cycles bearings are going to eventually wear out. It seems bearing noise, whine then failure is most common failure mode for the MGU. It you eliminate these zero to whatever rpm the bearings are spinning when the engine is cranked, you eliminate excess wear and the bearings are going to last much longer.

Purchased my 2023 Ram 1500 5.7 with e-Torque brand new in Jul 2023 and sold it at the end of March this year. It had 25,6XXX miles and I had zero issues of any king with the truck.

No, they don’t disable anything except start/stop operation.

 

[DanAR]

That’s what I thought.

 

[18harvest]

The starter only turns the engine over when you first start the truck.when stopped the e torque unit uses the belt to to turn the crank.placing more stress on the bearings i would think.i think that's how it works.but I've been wrong before

 

[John Schmidt]

I'm thinking that the MGU bearing failure is tied more to the fact that they (the bearings) are spinning anytime the engine is running. If they are poor quality bearings, they simply degrade over time/use, and ultimately fail. While I do believe that the actual act of the MGU starting the engine may contribute to the problem, I just think it's less of an issue than the overall bearing spin time .. but again just my thoughts - no data to help.

[mikeru]

It sure is fun to speculate. Too bad Ram will never release said data. It's likely a combination of both. And since there is no way to disconnect one from the other and still have a running truck it's a moot point.
