Great detailed video. one tip though, torque the thrust arm with the wheels on the surface so it’s sitting right when the weight is on it, otherwise it will be always in stress and you’ll go through bushings really easy.

You may want to check when to tighten the thrust arm on the chassis. I believe it must be done under load, in other words, tires on ground.

Good video. I am replacing all the components of the passenger side. the driver side was done a few months ago by someone else. It looks easy enough for me. Tie rods as well. I watched your video. As someone pointed out I torque the nuts once I put weight on the wheel.

The torque spec for the bushing end is definitely not "infinite" as you hyperbolically said at around 9:06. The proper spec is about 80 ft/lbs + 120-180 degrees.

Additionally to all the "experts" in the comments: You do not have to put weight on the wheel before torquing, you just have to make sure the bushing end is torqued with the arm at the resting position's angle. For example, the lower control arm can be changed while in the air but it needs to be held at a 90 degree angle while torquing it, which makes it simulate the angle it sits at while under weight on the ground.

Nice! 21mm is key to the heart of merc suspension.

Hey thanks for your video! I wanted to ask how are the thrust arms holding up? Been debating between OE quality arms from FCP Euro or TRQ from eBay lol I'm at 160k miles on mine and the ball joint squeaking is bugging me. Thank you!

Big thrust arm nut 80Nm+120'. Torque should be under load or you'll tear rubber parts, drive weird, and get noises.

Yet another incorrect video about replacing these arms!

You MUST tighten the opposite end to the ball joint with the bushing loaded (ie with the weight of the car on it) otherwise you will just tear up the new bushing! 😡
