'99 TCase possible leak
'99.. Z71.. 5.3L.. 4x4.. 250k
OK.. I did a stupid/lazy thing last week. Instead of doing my own oil change - outside in 10* weather - I opted for a drive thru quickie. In getting the crankshaft sensor in yesterday I noticed that the top of the transfer case appears to be wet, autotrac II level appears low and there is oil spewed all down the LEFT side of the undercarriage.
Not getting any idiot lights anywhere. Engine oil dipstick says it's OK. Haven't wanted to try to shift into 4x4 w/o sussing things out first but winter is upon us and I'm going to need it soon. Other than the soaking, w/o using the 4x4 everything seems to be running as normal.
Wondering 2 things:
Any chance that the pit crew somehow "overfilled" the case if they decided to top off?
I don't see any leakage around shaft seals, etc... Is there a usual suspect in a transfer case seal/gasket failure especially given the mileage I've got.
