Added DIY video for replacing tension struts/thrust arms

I added a DIY video for replacing the tension struts/thrust arms on a 2007 X5.
This is a common failure point in the suspension where the ball joints fail and make noise.
The hardest part is removing the 27mm star nut from the bottom that has a lot of torque applied when tightened. I basically had to use my whole body and get leverage to undo these, but I was able to do it with a closed end wrench.

Thanks for the video! I am just in the middle of the project. I am lost with which torque to use - can somebody help? I have 27 mm wrench which I used to undo the start nut at the bottom part of the thrust arm. I guess I am not able to use torque wrench as for the 18 mm nut at the top?

Also, I understand that I need to torque when the suspension is under load. I have the car on two stands and the jack under the front jacking point. Can I just use bottle jack under the suspension to load it?

Thanks!

Get some wood or concrete blocks and lower the car onto the blocks. Be like sitting on th ground, but you can get under....

Thanks, good idea! Unfortunately, wood or concrete blocks are not that common in my neighborhood Looking for these torques - I believe I should be here

https://www.newtis.info/tisv2/a/en/e...mounts/4Pz8zV2

If I read correctly, the upper nut spec: Jointing torque 100 Nm, Angle of rotation 90 , the bottom nut: 80 Nm

What does it mean "angle of rotation 90 ? Should I torgue 100 Nm and then additionally move wrench 90 ?

For the bottom nut, I do not have 27 mm socket for my torque wrench. Is there any trick not to overtorque 80 Nm?

Yes 100Nm and then 90 deg more. Indeed you cannot acces the nut with regular torque tools, so the only option is to torque at the bolt.

No there is no trick that get close enough on that 80Nm nut. Go get a socket.

Ramps or blocks is good for getting to ride hight as ard said. I marked the shock/shock cover edge before jacking the car up, and used that as reference for compressing the suspension again. Its tricky as that lifts the car off the jack stands. Put some additional security in place, and dont get under!
