eTorque Bearing Replacement, Fixed Grinding Noise

[kwimm1991]

UpNorthEngineer thank you! I'm currently trying this. After I got the casings apart I noticed my rear bearing has a snap ring. You don't mention this. Curious if everyone's had this ring and if it's even the same bearing?

Mine did have the snap ring as well. Same process that he posted otherwise.

got the #6661K86 for the rear
For the front the #4668K327

That front bearing is not sealed and will be open to the environment.
6661K126 should be the sealed version' in precision, ABEC-3 grade.
I'm wondering if a set of angular contact bearings like the 7305-2RS (6680K47) would be tougher and more appropriate for the loading?

Just thinking out loud here...

Great info and thanks very much for sharing. After about a month of starting to hear some bearing whine, my MGU is now dead with no charging at all. So I'm probably past just a simple bearing replacement and I've got a dead $60k truck.

FWIW, I came across a reddit post showing the bearings as 6003 and 6305. The 6003 would confirm what @UpNorthEngineer measured. Not sure on that front bearing but I'm passing the info along in case it helps anyone.

Hey would you mind sharing that post so I could read through it?

Before pressing the new rear bearing in i placed it in the casing and it seems to drop in pretty easy. What prevents the bearing from spinning inside the casing once its in?

Thanks for the information & write up. I'm going to order that rear bearing and give this a shot.

Currently having the same issue with my etorque. Did any of you replace the front bearing of so how did you get the front pulley off

Read back in the posts. IT WORKS!!!

Ordered the bearing, had my mechanic install it. He showed me the old rear bearing. It was shot. Truck now works great! thanks again.

Mine has a snap ring just like yours. I took the picture on my post before I put it back on. I assume UpNorthEngineer’s had fallen/ broken off due to the condition of his bearing.
