My 1977 Chevy C 30 Deluxe 1ton flatbed has new clutch, universal, brakes,
just completely tuned-up & has run great since 350 rebuild was installed 10
years back. It has hauled TONS of roofing materials & firewood successfully
as we also beefed up the leafs. In the last 90 days or so the truck has
been doing this weird “grabbing & popping” making it difficult to pull away
from traffic signals, etc. even when not loaded. So after bringing in a
load of Oak firewood late yesterday, when we unloaded and tried to move
forward, it would NOT budge. Acts like maybe rear end is locked up or
something. What do ya’ll think please?
I’m a mechanic and worked at a chevy dealer for a long time, fixed lots of
these, replaced a lot of transfer cases because it was to late, but if we
caught it early, just the rear case half could be replaced as well as the
update, that little anti rattle clip on the case is removed and a new wide
one that fit over the pump and wrapped around that edge, problem fixed, no
need to get that aftermarket pump, with that block at the end, because
basically the updated piece from GM becomes that block.
Just needs a slip yoke eliminator now
nvg 246 transfer case
thank u trucku for the infomation and youtube
does this apply to the Escalade transfer case as well ? I understand
Escalade uses pretty much the same GM parts as a tahoe.. I want to make
sure before I do any unnecessary work
i am having this problem with my 2003 1500 hd is that bearing for the rear
output shaft pressed on?
so what if I used jb weld and threw some duct tape over it?
Does anyone know which side the vehicle speed sensor is on these year
models?? Right or left on the back of the transfer case??
I had changed the trsnsfer case cuz of oil leak by the same reason I need
the part no. And how to buy it. my car is superbun chevy k25 year 2005
Thank you
@Trinity73160 seriously??if you can’t figure that out then you don’t need
to turn a wrench.
Does this apply to NP233 transfer cases? 96 GMC Sonoma/S10.
merchant-automotive is were u can get the pump upgrade
happened to my 02 silverado twice. the first time, the dealership “fixed”
the problem with the same setup for $1700. the 2nd time i took to local 4wd
shop and they fixed it correctly for $950. both times had to replace the
half case. dealership is scum. should be a recall
Good info, I didn’t know about this problem with aluminum NPs. Still, the
better fix is to upgrade to a full-time cast-iron t-case 🙂
never buy GM 4WD truck 🙁
I have the same problem or idk I need help, my 4×4 v8 k-1500 1991 I place
it into gears and it will only roll one of the 3 wheels what can be the
problem there? Help? They said my
@420wurtz sounds like you’re running an LSD (limited slip differential) in
the rear with an open diff. up front.

post the link but youtube wouldn’t allow me

hey matt slap that fuckin bruno
Great video, however nobody has any videos on a complete disassembly and
reassembly of GM 246 transfer case nor can I find any manuals on this type
of transfer case. I can only find partial disassembly video’s on any
transfer cases. Sure would great for somebody to make a video on a complete
disassembly and reassembly of a GM NP246 transfer case for us guys who
don’t do this for a living.
what is the name of the kit? dose oreily’s offer it or autozone??
