Guide rod bush

[Larry & Norma]

I need to replace the bushes (A0009883310) in the guide rod/lateral support rod (A1113300330) of the suspension/steering.
Not too sure what this rod does? Is this a diy task or will it require a fly press etc. Thanks

Larry .... I am also stumped.  Attached is the page from the parts manual.  Item #125

Hi Jim,
It is part 126 which fits into 125.
This 'rod' seems to connect the subframe to the chassis. Both bushes are totally shot on my car. This was not picked up in a
recent MOT, so maybe they are not too critical. Nevertheless i will order replacements.

Hello,

The front suspension on these cars has rubber mountings (subframe mounts). The front suspension actually "floats" on these rubber mounts. The support rod you need keeps the lateral movement of the subframe in check . It is the "rigid" connection between the "floating" subframe and the chassis.  It is not a safety issue, since the front suspension is also bolted through the rubber sub frame mounts. However it will tighten up the handling and feel of the front suspension a bit.

I heard these were becoming NLA ?  The same item was used on all W110, W111, W108 and W109 Mercedes sedans coupes and cabs of the era 1963 through 1972. Here again this would be a easy item for a supplier to reproduce if it did become extinct.

The more common failure in northern climates, is that they rust and break into two parts.

Thanks for that Joe, I have two bushes on order. Is there any set up required on re-assembly? Also what is the torque setting of the mounting bolts. Cheers

Hello Larry,

I do not suspect that a torque setting is called out for this obscure procedure.  Most pros just use "experienced feel" on this.  You can look up standard torque setting for this diameter metric bolt, (mild steel), if you need to.

I have only heard of replacing the whole rod, so bushing it will be new for all of us. Keep us up to date. You may be able to use your bench vice as a press to install the new bushings ! ?

Just thought i would update on this. Did the job today, took less than an hour to remove the rod change the bushes and replace the rod.
The old bushes almost fell out, the new went in using a vice with a suitable socket to push them in. Much cheaper than replacing the complete rod.
