One of the primary causes for rubber parts failure is people allowing their engines to spew diesel contaminated oil all over ~ diesel fuel is ruinous to rubber so expect the entire front suspension bushings to be shot when every time you pop the hood there's an oily mess .

I'm back (the bloke with the small nuts). I was going to post a reply when I completed the job, but it has been frustrating getting parts (at a reasonable price) and so the job is still a work in progress.

I did send back the passenger side Lemforder control arm with the stripped bolts and ordered a new genuine Mercedes control arm. I have attached a picture comparing the torsion bar bolt heads of the two brands. The new Mercedes bolt head has markings and serrations around the diameter of the head. The Lemforder has nothing. The genuine Mercedes bolt head looks more legit to me. How about to you?

I wanted to purchase new pinch bolts and torsion bar nuts since they didn't come with the new genuine Mercedes control arm. And then I decided that at the same time I would order a genuine Mercedes control arm for the driver's side to replace the Lemforder since I don't trust it even though I didn't strip the bolts. And that's when I ran into another delay. The parts company said that part was obsolete and unavailable from Mercedes - none in Germany! I will resume my quest on Monday, calling other on-line part suppliers.

You're best placed to make an assessment as to quality with both items side by side, if it's any consolation I went through the same sort of process when overhauling my S124, not easy to make a compromise.

Out of all of the parts replaced (and there were lots) only three items had issues, as follows:

Track tie rod arm x 2, these were TRW but much lighter than the ones removed, no problems as yet but couldn't help notice the difference (maybe a new lighter design?)

Meyle center bearing, burnt out within a few weeks, oddly enough actually made by a very reputable company and not Meyle.

Exhaust back box and mid section, made in Germany, took two months of backwards and forwards checking compatibility, item eventually arrived - fitted, sounded dreadful, emailed company gave 2/3 refund immediately (not sure what to make of that).

Some of the Meyle parts are indistinguishable from MB originals, the other thing worth pointing out is kits, these tend to be more complete - rubber center couplings are a good example, 3 bolt washers included, bolts of very high quality.

..just my opinion of course, don't really do the miles or have very harsh weather conditions here.

Crappo Chinese hardware that's dangerously soft can crop up anywhere ~ we got some of it from Bell Helicopter when I was with L.A.P.D. Air Support .

Luckily the guys caught it before installation .

The welds on the M - B part look better too .

After one month of being unavailable, Mercedes finally made available the driver side lower control arm. I installed both the driver side and passenger side control arms directly from Mercedes and torqued the torsion (sway bar) bolts to the specified 20NM without any problems. There was no galling of the threads as had occurred with the Lemforder parts. Mercedes control arms were manufactured in Slovenia. The Lemforder control arms were manufactured in Italy. My recommendation to anyone thinking of purchasing Lemforder part number 124-330-30-07 (driver side control arm) or 124-330-31-07 (passenger side control arm) is to think twice and purchase the Mercedes OEM parts for this application.
