He explains it in that video much better than I could. As for the process, go to Youtube and search ‘Viscous Coupler 2005 Vibe’ and there should be a video 6:38 long by South Main Auto repair. Once the coupler is off, you can either replace the coupler radial bearings then, or wait and do it afterward.

Once it is free though, you will know, and you will likely have oil leaking out of the pinion seal. You may need to pry a little, as the carrier housing is also aligned on dowel pins.These bolts are what holds on the part in diagram A, part #3 I believe that they are 12mm, and you will like to need to bend some of the heat shield out of the way, and use extensions and swivels. You likely want to do this anyway, as it bolted to the rear carrier is quite heavy. Next, since I was replacing the viscous coupler bearings I removed the viscous coupler assembly off of the front of the rear carrier.I never took the driveshaft out of the front (transfer case), I just supported it in place. Where the driveshaft connects to the coupler, there are alignment pins, so you may have to use a pry bar or hammer to gently tap it loose. In order to dis-engage the driveshaft from the coupler, I had to also unbolt the hanger bearing as well, and tried to leave it all supported on blocks. I have read that you cannot let the driveshaft bend beyond a certain angle, so have some supporting blocks ready. In order to rotate the driveshaft, I found that 1 front wheel had to be lifted off the ground as well. You will have to likely rotate the shaft part way through to get at them all. See diagram A Part #5, this is what those bolts attach to. Unbolted the driveshaft that runs from the transfer case to the viscous coupler assembly, there are 4 bolts (14mm, I think) that need to be removed.Jacked up the back end of the car high enough to comfortably get under it.ĝrove the car up onto ramps on the front end.You will save headaches down the road if you spray it all in advance and allow it to soak in. As well, use lots of penetrating fluid / spray when doing this, and keep a few steps ahead when planning your next few moves. Here are schematics at the bottom to use as reference when reading below. I am glad that we persevered, because in the end it was not that tough.

I was quoted $500 for the 6.5 hour job, and there were times when doing this install that I thought we might have been better off doing that. If you are not 100% comfortable with this, it may be a job best sent to a mechanic.
#2005 pontiac vibe red how to#
As with anything like this, I have been working on cars my whole life so know how to be safe while working on and under cars. I did this over a month ago, so there may be some smaller steps or details that I have overlooked, but here are the nuts and bolts of what I did. Sorry, I took no photos, so I will try to explain using GM schematics. At the same time I replaced the radial bearings and dust shield on the coupler as well. Here is a step by step report of how I remember removing the bad rear carrier / differential from my 2005 Vibe AWD and install the good used one I bought.
