Torque strut arms?
What are these? Do these compliment the lower control arms?
My 2005 E320-CDI is at the dealer for a routine transmission oil/filter change. Dealer called to tell me that the boots around these torque strut arms are damage and need to be replaced... $1100. Whoa. But not knowing what these are. From a few online pics, it appears to be another arm just to the rear (at a 30 deg angle) of the lower control arms.
Can this be easily DIY?

Strut is #140 in diagram – left part #2113304311, right 2113304411 (parts.com $138 each). In addition, if not already done replace the hydro-mount torque strut bushings (#145) with solid rubber part #2113331114 (24.72) they have an increased resilience towards deforming during suspension loading.

Is it possible that these hydromount torque strut bushings are responsible for the lack of solid feeling in front end. At low speeds I feel stuff in the steering wheel that I can't see in the road. It almost feels like there is some clearance in some suspension member. Also can a one get a dealer to replace them is there a service bulletin on this?

Thanks as always for the prompt response. Whats interesting is that the 4matic setup looks sturdier that the rwd setup which is understandable. Sometimes I wonder if what I am feeling has something to do with the 4matic. Do you know what the round element in the middle of the lower control arm is? It looks like a bushing of sorts. Does another link connect to it?

W211_E320CDI
i know this is an old thread but i have a similar problem as i had no idea what a torque strut was, i have just bought a 2004 W211 E320cdi estate and it has got a judder when both accelerating and braking although the braking is worse. i took it to my local mercedes dealer in sunderland and had a health check done.
They said the ball joints on both the Torque struts are worn to excess, my discs front are undercut and corroded Rear are corroded and front pads are 80% worn and my brake fluid is dirty. Also slight play in bottom ball joints and rear prop coupling starting to split. As well as telling me i probably need a new radiator and gearbox (which i very much doubt)
well i wont expose you to the cost they quoted as you can guess it was nearly as much as i ha just paid for the car lol
basically i have replaced the front discs and pads, in my eyes and my local mechanic the rears are fine. as i have limited spare cash and want to resolve the juddering as cheaply as possible can someone in the know suggest cheap ways round the work that i need. also any ideas as to whats causing the juddering?

W211 E320 cdi
Car juddering on acceleration
My E320 owned since new ( 2005) has suffered this problem on 3 occasions
1 2009 new turbo and associated bits £980
2. 2015 limp mode in Italy Inlet actuator €1200
3. May 2018 inlet port actuator + new ( refurb) Turbo £1660)
the codes thrown up lead to other faults being shown and this can lead you astray
i havecchanged the fuel filter + oxygen sensor but it eventually came back to the old turbo
