SLS rod failure

[kwontumspeed]

Never thought this would be a maintenance item, but my suspension went super wonky. Luckily I wasn’t but a few blocks from home. The rear was squatting and something was off. Well the bushing to the top of the rod had deteriorated and the knuckle dropped out and was hanging freely.

A 124 320 09 89 - $20

I never fiddled with it much so maybe age took its toll. A good $20 spent.

I just bought one, I saw that the bushing was shot. Ew from mb is around 20 and keep the old to match the length pre-install

Indeed an often overlooked service item on rear SLS and full hydro cars. Us 6.9 guys know this only too well. Most of them I've seen on 6.9's have been cactus, amazing to think that this little rod/bushing can have such a profound effect on things.

The SLS adjustment rods are available from MB, for a discounted price of ~$22 apiece, but there are none in stock in the US, and they must come from Germany. I have two of them on order for my parts stock.

Interesting that @kwontumspeed's rod shows a December, 2019 production date. That's some FRESH stock !!

Mine took a week, installed it today with my new rear legs. It was identical length of the original.

Is this any different to the W116/W123 part (1233201489)? I don't care about the length of the rod, just the ends.

Thanks

In case nocfn doesn't see this request, per: OWNER - nocfn | Owners and Their Cars (see post 644) it looks like you could use the 123 part number and just swap the rod, if necessary.

Better still, use the 124 part as it's about 1/2 price from dealer as the 123 part at worldpac

That is what I suggested in the post Mike quoted

Are folks saying that the 124 rod works perfectly on the 126 chassis?

I can't remember what the W126 SLS rod looks like but I think that it's different to the one pictured for the W124 which looks like it uses the same ends as the W112/W109/W116/W123

I think the W126 is different

My sls rods for both cars are similar, but is a 91 C126 (w123 PN) and has the same dogbone joints as the 94 W124 (w124 pn)
