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. :)
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...:(
Nick Stageberg: This and an oil change video are the only how-to's I have on this platform :)
Jean Agosto: i have a 2002 trailblazer ext that during the winder i use 4x4 when its snowing and need to get out of something, however usually i run it in 2x4. 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?
Nick Stageberg: The front diff on the that platform is extremely involved, I know it includes removing the engine oil pan. I would not put the job at less than ten hours.
Nick Stageberg: 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 :(
Doug Moff: I have a 04 reinier and i got stuck in mud and the light for awd came on and the front wheels never spun in the mud, how can i check the awd to see if it is working?
Nick Stageberg: The front axle disconnect is on the passenger side, and the diff is on the driver's side, the noise is almost certainly coming from one of those two. You can get these remote controlled magnetic microphones that can make tracting down those noises a million times easier.
Nick Stageberg: The automatic 4wd on the bravada only engages in limited traction situations, it does not run all the time. If you are hearing a noise when you are in 2wd mode that is encouraging, it could be an issue with the front axle disconnect, which is just cheaper and easier to service than the differential. You really need to try to localize the noise if it all possible, I know it can be difficult.
Nick Stageberg: 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?
Jeffery Plomb: 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!!
Nick Stageberg: Thanks for the tip!
331sbf: I use a flat wide Stanley pry bar to pop the CV out that I got from Walmart works perfect.
