nicholas elias: On My bro in laws trailblazer the passenger side wheel does not engage during 4wd. I think the axle disconnect is the issue. The actuator works but i hear a clunk and no engagement
Mark Mogan: My wife's car is an 02 Bravada with 190k miles on it. It has 2 new front wheels hubs, new TCCM and transfer case actuator motor. The car does not operate in AWD. On a wet road or gravel road the rear wheels are the only ones that turn. No noise heard while driving. With the car on 4 stands, there is a slight tick, tick, tick from the center front axle area when either front wheel is spun by hand. I started the car and put it in drive , at idle, there was a significant gear grinding sound coming from the front end, yet neither wheel was turning. Everything I'm reading sounds as though I need a need a new front intermediate shaft assembly. Any thoughts before I buy the part install it?Thanks.
Esegiel Nuseb: Hi my chev blazer 4x4 is not disengaging from 4x4 and I want to disable or disconnect it until I bought the parts
wildwwa: we have a 2007 trailblazer that front assembly is actually broke what might have caused this where the axle goes into side of oil pan is broke loose and rattling
paul deluca: Thank you for posting this, I had changed the oil and was cleaning oil run off and decided to see how things where and noticed there was at least 1/2 to3/4 inch of play on the inner CV axle. Now I know what I need to fix.
Stanley Waggoner: I recently replaced this front axle disconnect assembly on my '05 Chevy Trailblazer with 125,000 miles. Symptoms were a soft rattle sound coming from the front passenger side at low speeds. Sounded just like a loose muffler heat shield. The sound only occurred in 2WD......no sound in 4WD. My wife had a GM dealer look at the car and they said it was a bad front differential and would cost thousands to repair. I didn't believe the dealer and purchased a new disconnect assembly from Dorman Products. After pulling the right front axle, then pulling the disconnect assembly....needle bearings fell out of the unit into my hand. I was so relived to learn this was the only bad part. Differential was Ok. It's been two months since the repair with no problems. .
Ian Thompson: Do you know if my 2000 Bravada has a disconect? My AWD doesn't work. When the rear wheels spin, the T-Case shifts, and the front driveshaft spins. However the front wheels do not. Also If I spin a front wheel the other does not spin... no noises, and Ive looked all over and cant find a front diff disconnect.. Im thinking I have a broken axle internally...
Eric Warren: Great video thank you! I wish I had watched it before hand though.........
Nathandm78: Wow! An EXCEPTIONAL video!! Clear, concise, directions. Excellent camera shots. I now FINALLY understand how the front axle disconnect is put together on my Saab 9-7x 5.3 V8. Thank you! I hope you were able to fix your issue. :)
tlotb86: 03 trailblazer i never checked or got them checked my driver side is screwed lol i have what you were looking for in your video
NYRM1974: First of all I would have to be at least a hundred and fifty thousand miles before you even begin to experience a problem with the all-wheel-drive disconnect assembly .. The most common problems are the following: defective wheel hubs or the lack of lubricating the transfer case at least every couple of years or 60,000 miles whichever comes first or a lack of servicing the front differential by changing the fluid I do mine annually on my 2004 Chevy TrailBlazer EXT LS 5.3 liter v8
Christian Martinez: I have a 02 bravada if i have a rumble in the driver side what am I looking to replace the noise starts at 20mph and sounds like a bad wheel hub and the noise goes away slightly when i steer left can you please guide me its grandmas suv and shes counting on me thanks
Robert Simeone: Nice video but I must say It would have been a lot better if you actually showed some of the disassembly.
bob good: Gonna do this tomorrow night. Thanks for the video. Don't know how I made it through 50 years of wrenching without youtube.
danielgr101: 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.
Ralph Connor: 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
Saul Zermeno: 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?
Nick Stageberg: Unfortunately I feel the same way. GM's full size 4x4 platform is great, but this midsize platform was poorly engineered and seems to have had a lot of reliability problems.
TubeRadiosRule: Wish I had known about this video a coupe weeks ago. The front differential blew up on my 2004 Rainier and I had a pickleens 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...:(
