How are the wheel bearings on long range or performance holding up for you with lot of miles?

[gottagofast]

With lots of track days we have been replacing wheel bearings around every 75,000 km.

That’s really often, is that necessary or do you just do it that often as a safety precaution since your on the track?

What’s the cost to replace them for all 4 tires

I’m at over 100,000 so far (5.5 years) with no detectable issues with the bearings.

Same here. I have 115,000 miles on my 2018 M3P with no bearing issues. I do enjoy its acceleration periodically, but in general I'm a pretty gentle driver.

I meant wheels

Original bearings here.

Wheel bearings? Of all the things to worry about?

Teslas use the same "Gen 3" wheel bearing cartridge as every other car in the world. It's a cheap little module consisting of 2 ball bearings (not roller) that'll cost you $50 to replace if you ever have to, which you won't. The Model 3 and Y are lighter than many/most comparable vehicles so you should expect wheel bearing life to be even longer than forever. Note that bearings are indifferent to the power passing thru them, but Teslas have less peak torque at the axle than most modern cars anyway.

And the other person in here said he replaces his every 45k miles that takes his model 3 to the track

So it would only be 200$ to replace all 4 bearings even with labor?

I have never heard of wheel bearings being a common failure for Tesla or any car even with well over 100k miles.

We have some old gas cars at over 250k miles with the original bearings, I just wonder if the weight and torque of EVs could have a different effect on bearings

 

[Sweed269]

Track cars can wear out a set of rotors in a year. That means nothing for street use. You could get 300k+ miles out of the bearings on a street car. Race cars consume everything.

A strange item to fixate on. Of all of the things that could go bad, wheel bearings aren't even on my radar.

It is necessary because they developed significant play and became very noisy. The wheel bearings were not that expensive, around $500 per axle. Labor is free because I replaced them myself!

Performance model? and you have fun with the acceleration every now and then?

Not being sarcastic, honest question. How does acceleration and horsepower effect wheel bearings? I understand how a lateral load would.

Idk that’s why I was asking

Fair
I am not an engineer or a math guy, but my institution tell me that the spinning of an axel in a bearing would not put an unusual load on it making me assume that horse power would not effect it. Now weight, that's a different calculation..
