This is both a project update and a DIY video. In this video, I show how to make a tool that will press in new Mercedes W123 rear subframe mounts. I also show how to use the tool. check out my blog: mercedesdieselguy.blogspot.com
If not for my crumbled trailing arm, I wound not have done this job. What I did was coated everything with silglide and jack the rear up on both sides with a board and two 1/2" socket extensions in the bushing grooves. Wooden board on top of jack, 2 sockets on top of board and bushing on top of sockets. Its a balancing act but once you jack it up snug, the sockets keep the bushing from distorting and the weight of my 300TD Wagon was enough for the bushings to settle into place after letting it sit like that over night.. Now the hard part, trying to get the subframe to line up with the bolt holes.
Would you mind sharing how you supported the car to do this? I normal put the the jack under the mount that holds subframe to the chassis, but since you have to remove that plate where do you put the jacks to hold up the car's body? Likewise, do you just support rear subframe from differential whole lowering it?
My bushings are about 1/4" short of being seated on my 300TD. I am about to get parts to make your tool. I am wondering if it is really essential for them to be seated. The ride height would be a little higher. They are in very tightly, and the big bolt will prevent bushing movement. The rubber in the mount would be more compressed. This may not be a good thing. Comments?
I can't see a reason not to seat the mounts fully. I don't know if it would cause any danger NOT to, but I'm in no place to second guess the engineers who built the car.
Glad to see you got it to work! Very ingenious idea to use those pieces to make a press. How did you press the old ones out, or did they just fall out?
Tugboatpb The driver side mount pretty much crumbled in my hand. I didn't press the passenger side mount out. I got it started with a hammer and chisel, and then worked it out with a pry bar. Between prying it out and pressing in the new one, the passenger side took me maybe 10 minutes total to replace.
You may very well have caught an error in my description. However, the car is long gone and I have no way of verifying at this point. If that's the case, use my video as a general guide and build a tool that fits together. Apologies if there is an error, but as I said, I cannot verify at this point.
Hey Mercedesdieselguy, do you maybe have instagram? I would like to give you credits when I finish my project on instagram, together with other people who greatly helped me
I don't have an official MercedesDieselGuy account there. Only a recently-established personal account, and no photos. But, I'd love to see your work if you wouldn't mind posting a link here. Thanks for watching.
@@MercedesDieselGuy oh my god, I didn't get a notification you replied. Anyway here it is instagram.com/johnny.the.jacko/?hl=sr I didn't really post things I did. as it's my personal account, but there was a lot of work :D Sold it, and got recently a w116, which I will start working on as soon as it gets a bit warmer. Luckily, the w116 is in muuuch better shape than w123 was when i got it
