Greetings. I'm preparing to replace the 2 front lower control arms (both sides) on my 2010 S550 Base vehicle. The alignment folks mentioned there's no way to adjust alignment on these lower control arms UNLESS eccentric bolts are used on the Forward Lower Control arm.
My question is this, Although I've purchased the Eccentric Bolt Kit so that these bolts can replace the stock bolts for the Forward Lower Control arm (see attached photo), it seems these bolts WILL ONLY work in conjunction with control arm's that have a Bushing with an OVAL bolt hole (see attached photo).
The challenge I'm coming across is I can't find this arm anywhere. All retailers I've searched have the FORWARD LOWER Control arm but all of these come with the ROUND bolt hole rendering the Eccentric bolt unusable.

Can anyone shed some light on my options?
Wonder what part of the bolt in picture is eccentric? It looks like straight bolt. Washers have cut on one side that could move the bolt if there was an oval hole in the mounting point AND small stops that the washer works against like there is for the rear wheel toe adjustment.
I don’t think these bolts work for the control arm install in front.
the incorrect parts description in your photo is utter lies - they have nothing what so ever to do with the older style "eccentric adjusters" - they sell caster and camber adjustment bolts - best NOT used for caster, likely you'll just muddle everything else up
they fit exactly the same way I have described many times where you can use similar items to correct the bad build where you correct the right side camber errors from the factory, by using on the track control arms
picture shows camber adjustment.... FYI you do not need to use the silly weaker bolts - they are made, one) to give the adjustment whilst leaving the subframe lug in the way which forces the std bolt stuck in the wrong setting due to bad build at the factory, and, two) to give visual indicator to the workshop so they know a particular suspension arm is ready to play
if you know its wrong and wish to have a one off correction of the terrible manu bodge quality at the factory - grind the lug off the subframe and fit the original bolts AND just use the silly washers - washers are available as a separate bit than the "bolt kit", so that real garages can do the job correctly, once
NOTE: if you have the silly bolts likely you have no lugs - as animals blast the bolts out during maintenance using air tools and that cuts the lug off the subframe anyway.... (which is another reason to do it correctly using just the washers so the lug you want isn't vandalised)
