Rumble After Repairs
We have a 2005 E320 4Matic W211. We recently did the following repairs:
I'm not even sure where to look with this one. Any ideas?
- Replaced the driver's side lower control arm and ball joint assembly (genuine Mercedes part)
- Replaced the driver side axle (Parts Geek TRQ CSA82361)
- Replaced the front sway bar (genuine Mercedes part)
- Replaced the passenger side axle (Parts Geek TRQ CSA82314)
I'm not even sure where to look with this one. Any ideas?

It's the axle. Did you save the old ones? You can get a boot kit for the inner/outer. It's mentioned in a few other threads. Those cheap sub $100 axles just aren't made right. There's a reason MB charges $1000 an axle. The only vendor that's supposed to be good is GKN, but those axles are in the $300 range. That's why if the boot is just torn, you're better off putting on a new boot. The MB ones are around $40 and they come with a new bolt as you're not supposed to reuse the old one.

Well we're certainly open to the fact that it could be the after market axles but I'm still not tracking with how it could be making that noise when we're stopped. If we were moving and there was some kind of odd noise that makes sense to me but why would the low rumble be happening when we're not moving? What do you think is causing it?

So we spoke with the Mercedes dealership and they indicated that the "knuckle" also needs to be replaced when you replace the axles. Could that be causing the issue we're experiencing?

Did you save the old axles? Maybe GKN isn't that good either.

Knuckle needs replacing! That's a good one. The knuckle is what everything attaches to. The brakes, the suspension arms, the axle, etc.. If they say the knuckle needs to be replaced, it means that there is some massive damage to it, like a huge crack or someone took a big sledge hammer to it and deformed it. Highly unlikely. I've seen cars with severe front end accidents, where the front wheel is torn off, but the knuckle is fine. Knuckles are designed to take extreme amounts of force, because many things in the front are attached to it.
Your dealer does not know and has probably suggested you replace the most expensive item there.
