Hey there, I have 2008 Chevrolet Kodiak 6.6 LMM 4500 4WD . Trying to identify my axles and have been coming up short. Rear: Looks like I have a 13,500lb Dana S110 SPICER axle. 5.13 ratio based on what my spec sheet from GM says. Spicer is stamped on the housing. Aluminum stamp says S110-L Not sure what that means exactly? Front:????? Spec sheet just says 8,000lb (AWD) Front Driving. Very vague. I called the dealer and have had no resolution. What I see on the cast is REV-D, 53066, 169-7, 080103 and it has a cover with 12 bolts and no drain. Can anyone shed some light on this? I'm sure I'll have a few questions. I am the 3rd owner and from what I've seen and been told, everything is OEM and has not been swapped or modified. I have called the dealer, went over the spec sheet, spoke with axle retail stores and no luck. Thanks for the help in advance! Jason
