I have a 2012 R350 4Matic that clatters under acceleration due to a loose chain in the front transfer case. Is there a way to disable the 4Matic system to the front wheels until I can replace the chain? I have seen posts about a lever in the engine compartment that disengages the front transfer case on older 4Matic systems, but I do not know if that can be done with the newer 4Matic systems.

Thanks,
Andy

Why don't you replace the transfer case chain?

Time constraints and disposable income.

I hear you on that.

Hopefully, you can find a way to disengage the transfer case and still run the rear. Don't know what kind of codes the ECU would throw driving only the rear wheels.

I was hoping someone on the forum could help. I read that the older 4matic cars have a lever in the engine compartment that disengages the front transfer case. I have read posts about owners who disengage the front transfer case during the summer and then engage it during the winter.

Below is a thread about disengaging the older 4Matic system.
