    I have a SM 465 4 speed tranny and a NP 208 transfercase adn the stock crossmember and mounts but when i put my truck into four wehll drive the tourqe from the engine snaps the adapter plate in between the trany and tranfercase. I have replaced it twice and just snap it the first time I put it into 4 wheel drive.

    From past posts there should be a rod brace from the 208 to the engine/bellhousing. This helps alleviate some of the strain on the adapter.

    What kind of mounts do you have?


    What do your engine mounts look like?

    A.) I would check your motor mounts, and it would probably be a good idea to replace the inserts with poly ones, or step up to ORD's semi-solid mounts (cured my t-case adapter breakage woes). While you are replacing the motor mounts, it would be a good time to replace the t-case adapter mounts with poly as well (keeps everything the same). If you are only going to replace one set of mounts, the engine mounts should make a bigger difference than the t-case mounts.

    B.) Check to make sure you have enough slip in the front driveshaft. If the front shaft bottoms out, it can wipe out the adapter and/or case.

    C.) If your combo originally came with the brace from the side of the t-case to the bellhousing, it would probably be a good idea to make sure it's tight (or install one if there isn't one).

    Let us know how you make out.
