I am going to replace my idler arm bushings due to low speed sway + creaking.
Awaiting delivery of the bushes.
I have the bolt and washers.
The bolt has the top washer fixed to the bolt head and is not central as per most diagrams or pictures I have seen of them.
Washer is offset to one side top and bottom ?.
Is this an upgraded part designed to spread load and flex ?.

I do not know about your car model. It sounds like you are describing a bolt and nut assembly used in adjusting the camber in the front end. You will know when you pull the original bolt and nut off for comparison. It is also possible it will do the job okay if it is still the basic same size and the hardness is also the same.

If there are any doubts check it out carefully. The bolt used in the bearings may have a better finish for example.

It is called the eccentric arm by Mercedes over here in the Uk.

It is part of the steering mechanism,it is connected to the steering linkage and the other end bolts to the cars body,this is where this bolt is used.

I will post a picture up of it tommorow.

It was the correct part ordered for the car I am just curious why the washers are fitted this way.

Okay there might be a little confusion here. The bushings and retention or pivot combined bolt both wear with time. The bushings ride the shaft of the bolt. The bushing kit usually includes a new bolt I believe.

That of course is because it wears as well. I do not remember any offsett washers present on my idler arm bolts. There would be no concievable reason for them to be that way I can think of.

Thats why I suggested the bolt you have may be for something else. I hear you saying it attaches to something so we are not talking about the same bolt. My error I think.

Usually washers that are drilled off centre on bolts are to enable suspension adjustments in alignments. It still sounds to me that you may have a camber adjustment bolt and nut. It is about the same size as an ideler arm pivot bolt if you wish.

I cannot remember everything though so allow I might have made an error of some sort. Your picture will wake me up I think. I do not feel the least bit argumentative at all. At best just a little confused. We out here in the colonies use the american terminology for car parts as well.

The idler bolt normally has an inverted cup on the top of it to keep grunge out of the idler. I have always used an idler kit. It has the bolt and the bushes and washers.
Would be worth looking at a parts diagram. I have not seen an idler bolt with a offset washer.

There is no offset washer. You need the kit ; item 14.

Tip! Before you fit the 2 new bushings, BTW they are identical, take them apart, (lift up the seal on the outer end and push the center out), grease them liberally with a graphite grease and pack it between them when assembling. When I have fitted these kits I have found them to have little more than a trace of grease from the supplier.

The new bolt does come with the kit. It is not a wear item as it just locks the two bushings together. Bearings are inside the bushings.

I went to the parts shop today and you are correct it is a bottom arm bolt.

I had a look through his parts brochure and can see why he got this bolt in,the correct one is shown on his drawing with the two bushes fitted on the bolt.

I expected to see it as per most diagrams on this forum where it is marked out as a repair kit in exploded form.

The way his diagram was laid out the bottom arm bolt he gave me was the only one showing two washers and a nut.

Can someone please provide me with the W124 parts diagram as discussed above please?

This is the steering system. Set 11 is the idler arm bushing kit -



This is the lower end of the front suspension. Item 14 is the bracket that connects the tie rods from the steering linkage to the knuckle, item 5, which pivots on the ball joint, item 62. The knuckle attaches to the strut (not shown) which is both the vertical support and damper -



I agree with barry123400 that the eccentric bolt described is item 59 which is used in the fore and aft lower control arm joints.

The front suspension also includes springs and a front sway bar which are not shown. You can see the scallop near callout 56 in the lower control arm where the sway bar attaches. You can also see the lower spring perch in the lower control arm.

FYI, the low speed creaking in my 124 wagon seems to arise from the strut upper bearings... lemme know if changing the Idler kit fixes it!
