No metal in case to speak of just fine grafite looking stuff on magnet MUY QUESTION IS can i just replace chain w/out gears i asum chain has streched.
I'm having the same problem with my 2000 Denali. My four wheel drive transfer case chain stretched. I replaced it but I happened again. I just removed the chain and now driving in two wheel drive. The gears looked good so it may be the clutch plates or maybe position sensors. The solution maybe to just get a rebuilt transfer case.
Yes you can just replace the chain, I would not recommend it. Even if it is not obvious, the gears are also worn and have undergone all the stresses that stretched the chain, they may be ready to go soon, why take the chance, the engine has to be torn down to the same point to replace the chain as to replace the gears. I would replace all with a timing gear/chain set and install all new gaskets as it went back together. A timing gear failure could cost you a couple valves and/or pistons when it fails (piston on its way up with a valve stopped at full open when the gear broke).
Please take the time to rate this solution
If you replace just the chain, inspect the gears carefully for signs of run over (aka roll over) Look for signs of wear/distortion at the tips of the gears. If any damaged teeth are found, replace the gear as well. Any damage on the gear will only lead to corresponding damage to a new chain. When in doubt, swap it out.
