Love your tutorials. Professionally filmed and edited so very easy to follow. Wondering why you don't add torque values for tightening of components.

[@autodocuk]

Unfortunately, it is not possible to clarify the tightening torque, this information can be found in the technical documentation for the repair of your car. AUTODOC

They do...

[@karlir0uw]

Oh man! Looks so easy nice job 👍🏼

[@jeflores1000]

Great video!! Thank you!! May I ask what's the torque specification for the other control arm? Thank you

[@raymondharper]

80NMs. The road wheel should be placed on the ground before the arm is tightened up.

[@Bobbyabafarida]

Perfect Job👌

Good job

[@vladmoloce8915]

Will be required a wheel alignment after this work? Or didn t affect that?

[@autodocuk]

Yes, it is recommended to make an alignment adjustment after this replacement. AUTODOC

Thank you❤

Thanks.

Nice one lads

[@SarahSmith-dh5rv]

I have a c240 trying to find upper and lower control arms, including ball joints

I have a 2002 c240 trying to find upper and lower control arms, including ball joints

[@johnsmith-wl8dp]

hi, can you tell me why the large bolt is slotted? and if there is a certain way it should be fitted? thank you

[@RothBeyondTheGrave]

They're camber/castor bolts. The placement of the bolts adjusts...you guessed it....the camber & castor. I don't think they're all fitted with these bolts.

[@jeffclements2254]

Great video, you make it look simple! Quick question: should you put the wheel on before torqing the bolts? Thanks

[@autodocuk]

Before tightening the lever bolts, you must install the wheel and lower the car to the ground, the bolts must be tightened under load.

[@jeffclements2254]

@@autodocuk thank you very much for this!

[@christiantannen4548]

How do you know that the lower suspension arm need to changed?

[@ralmo9762]

Brilliant

[@prisoner4244]

I love this videos, they help me a lot how to repair my MB C 320 4matic, the only thing I don’t like is that in the App you can’t choose EEUU country location. just Europe.😕😕

[@shajigeorge1687]

Why not show How to fix lower control arm bolt because there wheel alignment slot comming? Could you show next video please Any way Thanks auto doc

[@autodocuk]

Thanks for the clarification, we'll think about what we can do with this in new videos.

[@giorgitkebuchava8868]

can u make video about changing the reinforcment bars on clk w209 (there are two reinforcment bars on convertible clk w209 in the front that conects subframe to the chassis)

[@autodocuk]

Unfortunately, we do not have such a video, you can find this information in the technical documentation for the repair of your car. AUTODOC

[@alpha-ne4fq]

Hi! Is it mandatory to jack up the suspension when you tighten up the bolts?

[@autodocuk]

It is recommended to tighten the bolts when the car is mounted on wheels, in this case we simulated the working position of the suspension with a hydraulic suspension.

[@grantcauston457]

Hi there and thanks for the video. What is happening at about 3:50 on the vid. What was "compressing" the suspension? Thanks

[@autodocuk]

The mechanic lowers the hydraulic strut, with the help of which he simulated the working position of the suspension when tightening the chassis.

[@markaltosmith7871]

I noticed the inner hole was elongated, assuming for adjustment. Does anyone know how to set this up ? It must affect the camfer

[@autodocuk]

It is recommended that the wheel alignment be adjusted after this replacement.

[@yorkymc]

Thank you class video on how to do thank you

[@autodocuk]

Thanks for your positive comment! Stay with us!

[@StuartOliver83]

Wish my w203 looked like this underneath

[@phillipcole-c7p]

why does it say use 21mm spanner on ball joint to undo but when to tighten says 22mm????

[@autodocuk]

Because the nut size may vary depending on the manufacturer of the new part.

[@jbrat4313]

Agreed but this video was very helpful!

[@autodocuk]

We are glad that this video was useful to you!

[@masisahim423]

Hey I have a c230 2008 base model rwd I want to change the exact same part but I can’t find the name of the part so anyone knows from where and what part should I buy plz thank you.

[@autodocuk]

Hi! To answer your question, we need more information about your car. Contact our support team and we will definitely try to help you.

[@MersyyLife]

Is "combination spanner #21" and #22 just 21mm and 22mm?

[@autodocuk]

Yes this is correct.

[@FixItRyan]

I've never seen copper grease before, what is that for?

[@autodocuk]

Thank you for your comment! Copper grease perfectly protects against corrosion and sticking of parts operating at high temperatures, thereby facilitating further dismantling during subsequent replacements. Best Regards, Autodoc team

[@jblack8149]

Yea doubt any mechanic would actually go this far for us

[@Anontesla]

I’ve heard you don’t want to tighten it all the way until it’s back on the ground

[@Leo555ZZZ]

He raised the wheel hub which has the same effect.

[@danielstone6228]

Why is it that you have to tighten it with the suspension pushed up or with it on the ground

[@SR1Records]

@@danielstone6228 Old comment, but maybe this will help someone else now wondering the same thing. If you tighten up the bolt with no load on the suspension, once the car is on wheels on the ground the arm will pivot, which will twist the rubber, which will lead to the rubber splitting prematurely. Another way to think about it... Put out your index finger on your right hand (as if you're pointing). Now grab it tight with your left hand. Twist your right hand index finger with your left hand. Doesn't feel good, does it? In this case, your left elbow is where the ball joint is. The ball joint rises when the car is back on the ground. So lift up your left elbow and keep it there. That constant twisting force you feel on your right index finger will be applied to the rubber at that bolt forever. The same thing will happen if you tighten up the bolt on the control arm before you load the suspension - once you load the suspension, the arm want to twist on the bolt, but the bolt is too tight, so the rubber takes up the play, which can make the rubber crack/tear.

[@fanyanacele4885]

But it looks like low control arm not front one.

[@autodocuk]

The lower rear arm of the front suspension is shown in the video.

[@ahmedhabib7161]

Its easy 😂 if ball joint not broke and nut not ruted and stuck
