Title: Trailing arms
Post by: cfm65@me.com on May 10, 2016, 18:48:53

Hi Guys,
Has anyone noticed that the left trailing arm is positioned further inboard than the one on the right?
The left trailing arm is about 5 1/2 inches inboard of the lower shock mounting and the one on the right is only 4 inches inboard of the RH shock mount. I wonder why
Although I seem to recall that way back(30 years ago) I noticed that on the 190 SLs as well.
Regards
Chris

I am guessing it has to do with the pivot point of the axle being biased to the right.

Yes, it is harder to get tools in the side that is closer.

Yep, a 36mm socket + reducer drive to 1/2 inch rathet does not fit on the far R/H bolt. I managed to get a huge 36mm spanner from our local hire shop in order to undo the far RH bolt.
All trailing arm rubbers replaced and the arms back in position.

I bought a socket and then we modified it to fit this application. We cut close to half the length of the socket so it would fit.

If you look at the chassis drawing in the technical manual this offset is clear to see.

The other benefit to facing off the socket is that you lose the chamfered lead in on the socket. You then get full socket contact on the bolt head. These bolts have a narrow width head and considering the required torque, you want all of the contact surface you can get.
