Had to replace lower control arms and knuckle

[Floridaman]

My' 24 Foundation Edition Beast has 67k miles. I started hearing a clunking noise when going over bumps, etc. Tesla just replaced both lower control arms and both knuckles and driven hubs.

I was surprised I had to do that already. Seems weird. It was about $3700 (after the 7k pcs)... Tesla service said it was normal wear.

I'm in love with the truck and wouldn't change it, but it is expensive...

How is the truck being used? 67k miles seems… low

At nearly 3 1/2 tons the tires and suspension components are going to wear out and need replacement.

I think your nearly 70k mile truck received a fair amount of mileage before suspension work was required.

Due to all the power ya don't realize how heavy they are.

Those components on a truck should last much longer. Smelling something called Tesla apologists in the room.

What was the cost of parts? I've gone through lots of control arms on BMWs, so I was wondering if those were a wear item on these as well. Hardest part with control arms, on BMWs at least, is that you need to torque to spec at ride height. Not too hard I'd you have a spare jack and take some measurements beforehand.

Control arm on my M3P broke under warranty. It's a common part to need replacing in other Teslas, it hasn't been long enough for us to know if it is a part the Cybertruck needs replaced frequently.

Thanks for posting the parts list and direct link. I did a full front-end suspension rebuild on my dad's ICE 1/2 ton truck at 110k miles (70-80% of miles on gravel county roads). Super easy and I would expect Cybertruck to be no different for those DIY-inclined.

Agree: "Knuckle: ?? (Weird thing to need replaced)" who knows, anyone's guess why this was replaced IE necessary versus proactive.

The parts are as below. I know it would have been something I could ha e done, but, honestly wanted to see if there was anything else contributing to the early failure. I know she's a heavy vehicle, but should be engineered to not need this much suspension work this early..

The vast majority of the miles/usage is on paved roads. I tow about 15% of the miles, but nothing too heavy (max 5k #s) and wouldn't expect that to contribute to this..

I know there are failures on all vehicles, but the SA said it was normal wear. I'd have rathered they said it was a part failures vs an expected wear item. I have not had to replace bushings or control arms on any other vehicle I've owned at less than double this mileage. My 2500HD had a much harder life and sold it with the original suspension (other than shocks) at 225k.

I got the old parts and will look at them tomorrow to see how they look..

Yikes, 67K miles is pretty early for major suspension work. A much heavier say diesel 1-ton pickup would probably last 200K+ miles before needing such work.

And post photos?

Reading the invoice. I can understand the complete control arm replacement as once bushings go often a full replacement of the assembly. I don't think Tesla pushes bushings often.

Yet knuckle assemblies on both sides usually is from some type of hard hit. Never seen a Tesla one, but they are cast metal.

There was a mismatch on FS upper control arms and knuckles weren't correctly aligned leading to play. Not sure if that was in your VIN sequence.

Replacing both $500 knuckles is questionable.

Yeah, sounds like knuckle was damaged by control arm slop and the hub was replaced with the knuckle versus swapping it over.
