Mercedes W124 4 Matic - Technology explained 

Sun Valley Mercedes in Pacoima, CA will rebuild your transfer-case for a reasonable cost. Send it to them for rebuilding and they will send it back. Impressive 100% locking center and rear differentials are much more capable than later versions of 4Matic. The W-124 4Matics are special enough to keep working and on the road. That is why I had my transfer case rebuilt and you should consider it too!

Just to add, i think the system is even more advanced than you explained. It also has the 50:50 lock in the center. I think the modes are as follows: Mode 0: RWD Mode 1: 35-65 Mode 2: 50:50 Mode 3: 50:50 + Rear is locked

Tu, Marcus, és um verdadeiro mestre mecânico que sabe do que está a falar e que explica este assunto complexo e difícil numa linguagem que o espetador/ouvinte pode facilmente compreender! Muitos dos meus pensamentos sobre os w124s 4Matic mudaram consideravelmente depois deste vídeo extremamente educativo. Muito obrigado.

Hello how are you?.. i have the opportunity to buy really cheap and in a really good condition one off those 4matic.. if the transfert its broken (worse case). How much could be the price of the reparations? ... Another question is.. the only complicated part to find its the transfert? Thanks in advance

i have the '91 sedan m103 4matic but i got it with the front shafts removed and transmission changed to the rwd version. This is actually a good middle ground ive discovered, the rear end suspension side is swappable with the RWD sedan, so parts are available and cheap. However, front end is expensive, but then it is built much much stronger than the regular w124. The 4matic side stands disconnected because like you said, i discovered that everything i needed to convert it back to 4matic was simply too cost prohibitive with no warranty on reliability. The previous owner had changed the rear SLS out also, but id love to get it back, just dont know how. As of now, it works and drives rather reliably. Overall a very Mercedes feeling car.

The trasnfer case really isnt that expensive to fix. Its just that not many have done it. The hydraulic pistons that pressurize the clutch packs wear out the cylinder walls and then, the hydraulic fluid leaks past the pistons into the case. It mainly just requires sleeving the cylinders and replacing the pistons seals. Id be interested in buying your oil pan if you ever delete the 4matic system.

Hi, I’ve just recently purchased a 1993 300TE 4Matic with 76k miles. How screwed am I?

I had a 91 300TE 4Matic. What an incredible car. Very capable when the system is working.

I own one of these wagons and converted it from m103 auto to om603 and 5 speed manual. I have tons of spare parts including multiple transfer cases. I'd like to help

My 1990 300TE 4-matic recently passed 500k km (310k miles). I dont know how, but the 4-matic still works 🤷‍♂️😅

Hi, I’m looking for complete front anti roll bar for S124 300TE 4Matic. Does anyone have something like this for sale or know where I can find it?

Excellent video and description of the system! I am starting to appreciate these old mechanical setups more and more every year, even though I am an electrical engineer born in the 80's :D

Excelente vídeo. Yo tengo un w220 4matic que supongo utiliza una tecnología diferente al w124. Saludos desde España.

did the 603turbo 4 matic come with a manual gearbox?

Great job

Hello Do you have an parts for 4 Matic?

Olá ,Adorei o vídeo ,Tenho uma carrinha s124 4Matic de 1993. Gostava de tirar umas dúvidas consigo. Obrigado

Do you know if standard w124 suspension etc is bolt on in the 4matic cars? Or are the bolthole places also different? Thinking about doing an engine swap and 4matic delete
