Hi,

I was experiencing a clicking noise and occasional shuddering during acceleration. The dealer diagnosed a faulty Transfer case and replaced it. The clicking noise it gone and the shuddering has diminished .... but it still shudders occasionally while accelerating in low gear. The dealer noted after the work was done that it would improve the more I drive the car. It's about 500 miles and still occasional shuddering.

I'm thinking that there's something else going on? Is that normal ?

Sounds like a transfer case chain costs about $150 or less plus maybe 2 hrs labor give or take.
If it's still doing it, they likely didn't replace the transfer case, just charged you one.
So, you paid the full dealer cost for a transfer case? Yikes!
FYI they can be repaired.

Sounds like dealer b/s to me. No such thing as a break in period for something that is meant to be balanced enough to operate smoothly. There's no reason a new transfer case should shudder. Does it get worse under hard acceleration?

Could be they've failed to install it properly or its just faulty to begin with. I'd check the fluid if only to make sure they actually filled it, and then go and hand back the keys and say "don't call me till you've fixed it." However, it could be something else like a universal joint on the driveshafts etc. which means they got it wrong to begin with.
