Rear suspension arms - bolted connections or standardization screw?

[e500.org]

Looking to replace all the rear arms etc on my E500, I am looking at EPC and selecting the correct parts is not quite clear (to me).

Assuming these parts are not NLA, does anyone know which repair kits (and therefore arms e.g. thrust arms) are correct for a facelift 1994 E500? I have an option in EPC for "[150] UP UNTIL BOLTED CONNECTIONS" or "[151] FROM STANDARDIZATION SCREW"

Many thanks in advance!

I believe "bolted connections" refers to the original hex bolts that fastened the arms to the subframe. The current version of the arms with 210 part number require the kit A2103504506 which consist of sleeves, lock nuts, and XZN "triple square" bolts.

Ok many thanks, much appreciated, it seems the new arms etc are those with STANDARDIZATION SCREW so therefore I think I will replace with all those parts.

I usually buy Lemforder control arm kits with new hardware in the box. Plenty of info already on the forum on the Lenforder kits

You may wish to proceed with caution --- I was able to get Lemforder 33-06 and 38-06 with COO = Germany, but it seems that everything at distribution right now with respect to Lemforder 34-06 has COO = Turkey. Therefore, I purchased MB branded 34-06s.

Also I am not sure what OE was supposed to be, but it seems all the bolts I received from Lemforder bolt kits are grey-coated and not cadmium plated. I think I will get all the Lemforder hardware separately cad-plated.

Also note that the Lemforder bolt kit includes the sleeve 210-352-00-43, whereas the MB version of the bolt kit does not.

I have a Lemforder kit from at least 3 years ago. The bolts include the same sleeve. They are also grey coated. The arms are made in Germany and Turkey. I'll check the numbers to see if they are the same pieces.

edit; Just my two camber struts (210 350 34 06) were produced in Turkey, as well. I don't see anything visually different than the others.

Thanks all, aftermarket parts are harder to get in the UAE so I'll try and get original MB parts.

Attached is the list I just sent to my parts guy so hopefully I've got this right for my car (crosses fingers). I don't know if any are NLA let's see...

Oh dear. 129-351-14-42 is DEFINITELY SOOOO NLA. It is so NLA that it hurts. Do a search for those aft rear subframe bushings on this board. It is extensively documented.

124-350-97-08 is also super NLA. Again - search is your friend.

Also, 124-350-04-41 is a kit that comes with bushings 124-351-19-42, but these are the wrong bushings because the tabs on these bushings are too short. Instead of the short-tab 124-351-19-42 bushings that come in the kit, you need tall-tab bushings 129-351-15-42. The problem, though, its that the 15-42s are NLA.

Do a search --- I posted diagrams alternatives to all this recently........ (including Febi which SOMETIMES but not all the time are reboxed BOGE 15-42s.)

A German company started reproducing A1293511442 (PN superseded to A2023510942, also NLA from MB)

Pardon Our Interruption...

Thanks - I think I have two in my spares stock

Thanks very much, the search is a minefield at times and NLA status keeps changing, appreciate the inputs though, may have to consider alternatives for those I cannot purchase

The bolts on Lemforder kits are the same identical finish as MB. They are a dull grey spun galvanised finish which is durable, more durable than a zinc plating.

I recently went through an order with these, seem like a solid COO Germany set of NLA subframe bushings. I have some spare pairs that I ordered which I'll be listing up for sale in the next few weeks.

Good Call!

Another source of COO = Germany reproduction aft rear subframe bushings is ME TECH Restorations, who is a w124 specialty restoration company in Japan. https://www.metech-restorations.com/product-page/w124r129-v8モデル-リヤサブフレームブッシュ-リヤ側左右セット-1293511442

These are 3x the cost (absurd), though of the CARUS ones. I have no idea if they are different or the same. However, the packaging of the ME TECH Restorations bushings are like fine packaged Japanese fruit. @dreaming.haze and I compared the weights of the CARUS vs. METECH bushings and both are about ~615 grams. Visually speaking, the METECH bushings have some paint dots that the CARUS ones do not have.



Below is comparison of weights to the pedestrian 124 bushings (124-351-02-42) and 201 bushings (201-351-28-42). Conventional wisdom prior to this fall was to use the pedestrian 124 bushings since the 036 specific aft rear subframe bushings are NLA. After this weight comparison of reproduction COO=Germany 202-351-09-42s (which supercede 124-351-02-42 and are themselves NLA) I am not so sure I would feel comfortable using pedestrian bushings.

As requested: pictures of the 202-350-34-08 kit that I have. PN on the bushings themselves is 202-351-08-42 (not easy to read on the photos). Not sure wether Ill install these or go with the ones that the catalogue suggests. Personally I prefer a smooth ride over a stiff one

I was able to find NOS NLA set of GENUINE MB 202-350-34-08 kit Aft Rear Subframe Bushings for only $68.99. Score!!!

As with @lightdude95 , I found that the part number of the bushings inside the kit were 202-351-08-42 (not 202-351-09-42) <-- please note @gsxr!



@dreaming.haze, @gsxr, @RicardoD --- at about 635g / 640g each, these MB bushings seem to be about 20g - 25g heavier than the CARUS / Japanese ME TECH reproductions. I am not sure that 20g / 25g will much any appreciable difference.
