Gonna do this tomorrow night. Thanks for the video. Don’t know how I made
it through 50 years of wrenching without youtube.
Greetings. I have a GMC Envoy 2003… When I turn the switch to 4WD it goes
for about 1 or 2 minutes (enough to get out of a bind) but soon after that
the whole vehicle begins to seize and won’t move forward. Soon after that
the 4WD service light comes on and I am forced to switch back to 2WD in
order to continue driving. Now I have no idea where to start, but it would
be nice to have a head start… does that sound like the Front Axle
disconnect to you? Thanks
I have a 2002 Trailblazer with this problem I think. Already replaced the
actuator and no change (front axle won’t engage when selecting 4WD). When I
had the actuator out, I pushed the plunger in that the actuator pushes
against and had to push it all the way in for the front axles to engage, if
I backed off any, the axles would disengage. The actuator didn’t fix the
problem, does this mean the intermit housing has to be replaced? The
actuator does activate when selecting 4WD, just front axles don’t engage.
Thanks for any advise you can provide.
Hi, I just replaced the drivers side front wheel driveshaft. I noticed that
some oil came out when I pulled out the driveshaft, where should I add oil?

Thanks for the tip!
I’m not 100% sure, but I imagine the dealer could read whatever codes are
thrown when the AWD service light comes on, and that will tell you what is
malfunctioning.
Thanks for the helpful How-to Vid. I’ll be attempting this on my Envoy this
winter.
hello nick. my name is jon and i have a 03 trailblazer and i noticed that
the seal up front on the cv axle is bad. is it really hard to do for
someone who has not done it before? Thanks JON
I have the same problem on my GMC Envoy. My mechanic got all the way to the
axel disconnect but said the bolts are impossible to get to without
dropping or shifting the motor. You look as if you did it while only being
jacked up. Could you please help us!
Just a little FYI, not all early model GMT360’s have the trans line issue.
Mine is an 02 and they are well out of the way. Good video though!
You should make a video on how to replace the hub bearing on one of these
bad boyz
Thanks for the vid. I fixed the rattling problem by replacing the sway bar
end links. I have to change out the cv seals now so this was very helpful
I believe there is a bearing inside of the driver’s side of the diff that
can fail and cause that chatter, I’m not completely sure. It is a sealed
diff and cannot be repaired. I actually had the exact same problem, bad
chatter from the front diff. I tore down the front disconnect on the
passenger side and it had no problems. I pulled the driver’s side axle and
put it back together and it was fine. I eventually just sold it like that,
pretty sure I needed to put a new diff in it. $ 🙁
Thanks and good luck!
Unfortunately I feel the same way. GM’s full size 4×4 platform is great,
but this midsize platform was poorly engineered and seems to have had a lot
of reliability problems.
The dealer is able to scan for codes present that turn on the 4wd service
light. I do not know of a way to pull those codes yourself unfortunately 🙁
It is absolutely possible to access the bolts with the motor in place.
your video is very good, but how do u loosen the disconnect assy from the
oil pan. Mine is stuck on real good. I have pried and beat on it lightly to
try and dislodge it, to no avail.Any suggestions u may have would be
greatly appreciated. I am trying to remove the oil pan on a 2004, gmc,
envoy, s4wd.
Unfortunately my first guess would be the different gears are wearing. I’m
assuming it only makes the noise in 4wd mode? How many miles on your
bravada? Do you run in 4wd often?
Wish I had known about this video a coupe weeks ago. The front differential
blew up on my 2004 Rainier and I had a dickens of a time disconnecting the
passenger side axle. I ended up having to simply unbolt the bearing/connect
from the oil pan and removing it and the outer axle shaft together. I’ll
never willingly own another vehicle in this series – too expensive to have
someone fix it for me, and too much of a P.I.T.A. to fix myself. I miss my
1973 IHC Scout II…:(
Oh I wouldn’t say it’s too bad, this video illustrates the steps involved
in removing the cv shaft. It does take a lot of force to finally get it out
once you have all the suspension components loosened up. Replacing the boot
once you have it off is usually very easy.
Yes, the link in the description has the GM part number for all of the
internal components of the disconnect. You may also be able to find a
disconnect assembly at a salvage yard for a reasonable price.
@IB4rmHouston Hah that is pretty much the best thing you can hope for!
Could be lots of things, your front diff, the disconnect, front drive
shaft, or an axle. Have you checked the fuel in your front diff?
@Larry59lew Do you still have the axle in the disconnect? For me that was
very challenging, and I wedged a chisel between the axle and the
disconnect. The disconnect itself came out very easily once the axle was
removed, I just had to pull the three bolts. If yours is not coming out
easy I suspect there might be some internal damage in the unit that is
seizing on the intermediate shaft.
My 2004 Bravada symptom is a “whine” that sounds a lot like snow tires on
bare road. Definintly not tires, though. A fluid change (special GM fluid)
in the front dif made it quieter for a short time, but getting worse. Any
ideas from what you saw on your project? Sounds more like a gear noise than
bearing, but I really don’t know what’s inside that differential case.
Thanks, M
The 2004 Bravada is full-time AWD. So I’m not sure if the answer is “all
the time 4wd” or “when the computer tells it to”. It makes noise whenever I
drive above 20mph or so. Mileage is 106,000. I initially thought that the
wrong fluid had been put in during a service, but it drained out and looked
like the blue fluid GM dictates for that part. Yes, it does sound like
gears. I wasn’t sure what gears were in the differential. I take it the dif
looks like a normal bevel gear arrangement?
Great, glad you found it helpful!
i have a 2002 trailblazer ext that during the winder i use 4×4 when its
snowing and need to get out of something, however usually i run it in 2×4.
i am doing a front suspection replacement and wanted to take a look at the
spindle disconnect or replace it if its worn..any how to videos on that?
looked like the noise was the brakes rotor looks scored on half of the
surface. im having problems getting diffs off oil pan as we are doing an
engine swap, from a trailblazer to a bravada!!
