Transfer case issues

I’m having issues with the TC on my ‘14 450. I had an independent shop tell me I would need a whole new one at the price of $5K, could I just buy a rebuild kit? If so any recommendations?? OE or OEM?

Typical issues , engine "popping" under load especially on steep grade.

Anyone have experience doing it themselves? I know it’s not a rookie job. Thx.

Usually it is just the chain that is stretched and needs replacement. You can buy it on Amazon for around $100. Some people managed to replace it without removing the transfer case.

I went another route - bought a rebuilt one on ebay and sent my old one to the seller for a core refund. So the new one cost me around $1600 if memory serves. An independent shop charged me $700 to replace it.

This is the website of the guy I bought it from: https://tcbmwx5.com

@mtm: Thanks for the link to https://tcbmwx5.com. I haven't seen this before. It looks like they offer a complete kit for our transfer cases. That's probably the route I'll go when it's my time!

This thread also has some great information. https://mbworld.org/forums/gl-class-...hain-info.html Including a link to a video of someone swapping the chain.
