Question 2009 328xi Rear Shock Mount Broken

My local dealer is telling me that one of my rear shock mounts are broken and is telling me that both rear shocks, mounts, and bumpers need to be replaced at a cost of $975, can't the mount just be replaced without replacing both shock assemblies?

If the lower shock mount is broken, it is likely due to a worn out shock. That is why he wants to replace both. Bumpers are probably jsut an upsell unless he is talking about the rubber grommets on the shocks.

Thanks for the input, I was just a little concerned that the shocks could wear out within 30k miles, seems like a design issue.

2009 328xi Rear Shock Mount Broken

I have to disagree that a worn shock would cause a mount to fail. To the contrary, if the shock is worn out, it will put less force through the mount thus making it last longer.

This is more likely then not a manufacturing defect in the shock mount, not a design flaw. Take it to another shop for a second opinion. I think you only need one new mount and nothing else. There's no reason to replace all those parts on such a low mileage car.

That's what I asked the service manager as I thought the mount alone could be replaced but he says that the shocks should be replaced when the mount is replaced as well, seem a little unnecessary and expensive.

Wouldn't you want to get a second opinion?

But, hey....working blind here. Kindly post pic of issue.

It's the little things. Like....
  • Upper or lower mount? That could make a difference.
  • How is it broken?
  • Why do shocks need replacement?
  • Stock shocks or aftermarket?

At this point, pic's worth a thousand words.

The dealer is "trying" to save you on labor costs. Shocks/strutrs normally need replacement every 60k miles depending on road condition and driver habits.

With the rear suspension already disassembled, it will save you money in the long run to swap out the shocks since they will have to be removed to replace the mount.

Just FYI, you should always replace suspension components in pairs, left and right. So if only one shock mount is broken, you should still replace the other side.

Take your car to a indy shop. They will be a bit less but then you have to get a loaner or wait around for the work.
