Repair-It

The upper torque strut on the passenger side has given up the ghost and may be responsible for some new nvh. I did accidentally hit the park button when attempting to hit sport as I switched from fwd to reverse and had a crazy hard park engagement/bang that may have finally ripped it apart.

Did you already post engine mount/torque strut pns somewhere?

I don't think so

Looks like lots of options. Lower torque strut is almost as bad.

I don’t know how to see / check the two “hanging” mounts without taking them out and looking at them.

I guess I could change both torque struts and see if that greatly improves. Seems like grumble is mostly during accel. I would think the others would be more idle nvh.

Here you go

The two torque struts are:
Lower - 246-240-12-09 - $122.40
Upper - 246-240-08-09 - $132.00

The "main" left and right mounts are:
Right - 246 240 24 17 - $195.60
Left - 246 240 23 17 - $244.80

I think I'm going to do both torque struts and see how things are. I know they're both failed, they're cheaper, and they're easier to change. After that I can reassess.

Hopefully I made it to the right dealer page this time:

ECS tuning has them for about the same price [apparently OEM is Lemforder] and those would come with a lifetime warranty, but one of them is special order/no ETA.

https://www.ecstuning.com/b-lemforder-p ... 00809~lem/ - $144

I guess I'll just go with the mercedesbenzpartsshop

Not worth it on this order I don't think since I'd like the parts soon and RI is much closer than TX, but these guys would've been $15 cheaper which could be a bigger delta on a more expensive order:

Ordered from mercedesbenzpartsshop and had them shipped. Hopefully they come in soon.

I thought OE was Hutchinson. Whoever that is.
