For anyone mentioning/wondering " you have to torque at ride height, etc", that's exactly what happened when the pole jack was used underneath the ball joint. He loaded the suspension, bringing it back to the angle it would rest at while loaded. He torqued it, then released the jack. If you're concerned, measure the distance from the wheels center to the top of the fender (before you raise the car). Then after installing new arms, jack up from underneath the ball joint as shown here & recreate that distance (now from the center of the wheel bearing dust cap since wheels are removed). Otherwise, you would need ramps, wooden blocks, or various professional lifts which no one watching this is likely to have.
Nice Video! Im replacing both upper and lower control arms, in this video it shows the lower control arm. Do you know if the torque specs are the same for the upper control arm?
Some of the symptoms of failure are: - the hinge of the suspension arm prematurely failed; - uneven wear of protectors; - deterioration of maneuverability; - the vibration of the car with strong deformation of the lever; - an unpleasant knock and rattle when driving over bumps and bumps.
The suspension must be in the resting position before the arm is tightened down otherwise the bush will tear. This fact has not been made clear in the video
Thanks for bringing forward this crucial point. I've watched this video a dozen times to find out at what point one need to tighten the control arms. When you mean resting position, is that with everything in place and tight (except for the control arms at the frame) when the car sits flat on the ground?
@@therandomstuff204 When the car is level on the ground you can tighten the nuts and bolts on the control arm. Remember, on the SLK at least, the bolts are yield type and after torquing them down, you have to turn them a further 120 degrees.
@@raymondharper Thanks for the advice 🙏 I see they also indicate the degrees with the torque specs in this video regarding the w204. Even though its not demonstrated. I'll just make sure checking some other sources. Once again, much appreciated 😁✌🏻✌🏻

Thanks very good clear video, presume you have to remove under trays first
What's the symptoms of this particular arm..the lower 1?
Some of the symptoms of failure are:
- the hinge of the suspension arm prematurely failed;
- uneven wear of protectors;
- deterioration of maneuverability;
- the vibration of the car with strong deformation of the lever;
- an unpleasant knock and rattle when driving over bumps and bumps.
Hi, I have a question, is it a Macperson or a double wishbone suspension the front suspension of this car?
In this case, the car has a multi-link suspension and not a MacPherson strut.
Great video, can you also do a video for track rod ends, tie rods, drop links and other suspension components pls

very good work my friend
is this what MB calls the front THRUST ARMS? or are those different?
Yes, that's the front thrust arm.
@@autodocuk would you happen to have the part numbers for the driver and passenger side?
Proper pro job
Thank you 👍
Let's not forget the wheel alignment after
Yes, it is recommended to make an alignment adjustment after this replacement.
Nice video but the music is irritating
What size ball joint puller required?
You can find this information in the technical documentation for repairing your car.
The suspension must be in the resting position before the arm is tightened down otherwise the bush will tear. This fact has not been made clear in the video
Thanks for your clarification. This can be very important for our viewers.

What is considered resting position? I'm gonna do this job tomorrow so would be nice to know
