Late Sportline is indeed 1243303607 and 1243303707 and works with big brakes.
Late standard is 1243303407 and 1243303507 but NLA, also works with big brakes. These were popular prior to NLA.
Early standard is 1243303007 and 1243303107 but doesn't clear big brakes.

The late Sportlines will be $700-$900 per pair, depending on the vendor... maybe try these guys in southern Texas? No affiliation, I haven't ordered from them before. Dunno if they charge sales tax:

are these sportline LCA good for 93 500E?

Nope. All the aftermarket late LCA's have junk balljoints. If you roll the dice on any of them, at least add a bunch of good synthetic grease to the balljoint before installing, and pray it lasts.

See post #9 earier in this thread. Why do your LCA's need to be replaced? If they are the late style and the ball joint is not damaged, rebuild them!!

Those are fine, but have been NLA for years. And, they will increase ride firmness / harshness somewhat.

Left side may be available.

Right side is NLA. If you can't get a pair, a single side is useless.

what about the 1995 E320, are those LCA available from the dealer? i don’t know the oart number for them
 
LCA style is based on the front brake rotor size. All 124 and 129 chassis with 294, 295, 320, or 334mm front brakes must use the late-style with non-replaceable ball joint.

Only 284mm and 300mm front brakes fit the "early" LCA with replaceable ball joints.

are those available from the dealer or aftermarket only?
 
All the OE/dealer LCA's are NLA, either both sides, or one side of the matching pair.

Only aftermarket is available for early or late.

NO aftermarket Sportline LCA's exist. Sportlines were dealer-only until NLA.
got it, so besides rebuilding the ones from the car on the late models what would be next best option?

and for the 95 E320, what is the best aftermarket option?

i will do some digging maybe i have a chance finding an OE set if not will do aftermarket or ill look for a rebuildable set in good condition

Next best option is picking up a good set of used ones from the junkyard to rebuild, and swap on. Ideally, from a car that was not in a wreck.

See above - best option is rebuilding OE LCA's.

Aftermarket, AFAIK they are all equally bad, pick the least bad brand name and add a bunch of grease to the joint before installing.

I haven't seen OE LCA's for sale in years. If you find any, don't be surprised if they are pushing the €5k territory like 036 headlights and SLS hydrolegs...

you think its possible to buy aftermarket LCA and swap the balljoint with OE joint?
 
Only for early LCA's.

Late LCA's have the balljoint welded in place.
if i go to a junck yard how would i know if the LCA are OE or replaced with aftermarket?

or ieven if it’s aftermarket but the earlier version with removable ball joint its fine?

The underside of the balljoint is unique on the OE late LCA's. Looks completely different than all aftermarket late LCA's.

Early LCA's with removable ball joint will touch the back of the rotors on cars that need late LCA's, unless you go nuts with a grinder, and cut a hole in the dust shield... generally not a good idea. And it doesn't help much because the early LCA's are also NLA.

What's the deal on replacing the bushes?
Bushing replacement is straightforward, just make SURE to match the position of the "nubs", as there is a very specific orientation for each pair of bushings. There are detailed photos on my website if needed. The special tools are helpful if you have them, otherwise you'll need to fabricate something to press them in without deforming the metal shells.

:banana1:
 
Thanks very much. Are OEM bushes still available?
No, all the bushing kits went NLA. Be careful though, MB systems are superceding some of the kit part numbers to a single bushing, which is crazy priced. AND, you need two different types of bushings, and it appears one is also NLA. So if your dealer says "sure, we can get that"... no, they cannot.

Best option is to use aftermarket Lemforder bushing kits, made in Brazil.

 
from what year to what year the w124 had rebuildable LCA? i want to look for a parts car and would like to know what years i should look for, thanks
it is based on the engine, not the year. Early LCA's with replaceable ball joints were used with diesels and M103 engines in all 124 chassis.

But these will interfere with the brake rotors on cars with M104 or M119 engines (except for early 500E with the smaller brakes).

:mushroom:

You should be safe with W124s from model year 1989 through 1992, for the rebuildable LCA. 1994 and 1995 are a hard "No" for rebuildable, and 1993 as said would depend on the breakpoint, so I would say no to that too, unless you want to research the VIN (or post it here) of the donor car.
 
There are exceptions. For 124 models delivered to North America:

The 1990-1993 300CE (M104) and also 1992 (M119) 400E all have non-replaceable ball joints.

The 1995 E300 diesel has replaceable ball joints.

There are additional differences for the R129 chassis, and ROW of course, where 124 diesels were sold through at least 1995.

On my long gone 85-300E I had these bushings replaced by a front end frame repair and alignment shop. I had removed them from the car and took them the the lower suspension frames and the bushings. For them it was an easy task and not very expensive but that was around 25 years ago. I would assume any shop that does front end repair work could do this work.

got it, so the early LCA will work on the prefacelift 500E but everything else would be aftermarket option and a lot of grease, correct?

Not all prefacelift 500E. The 500E break point was during 1993 USA model year production.

If the car has brakes which require the late LCA, for NEW LCA's, yes... aftermarket with extra grease added.

I have yet to find an OE late LCA with an intact dust/grease boot, and a failed ball joint, even with 200-250kmi. If the boot is intact, the joint SHOULD be fine. However when the boots fail... the joints generally don't last long once water & dirt enter. More info in this thread.

so all prefacelift 500E that date up to 1993, got it, thank you very much

is the ball joint still available from the dealer or is NLA?
 
Hello Dave,

I will follow your advice regarding "If you use SWAG, Febi, or any other aftermarket late LCA... remove the boot and re-grease the new ball joint prior to installation." I will not re-use the ball joint covers that came with the Swag LCAs', instead "I still have a few MB OE ball joint covers, I'm planning to install them on the SWAG for good measure."

Thank you Dave for your suggestions.
what is the part number for the OE ball joint covers?
 
All of the ball joint information for the early front LCAs can be found here on the forum in other threads. There should be multiple threads on the topic here.

Also, the FSM is also available here on the forum, for reference in the procedure.

ill check again, thank you
 
my apologies, i was not able to find the part number for the OE ball joint, can someone tell me the thread number that contains that information please, i was able to find only the rubber boot replacement part number but not the ball joint, thank you
