The differential in my 2004 Pontiac Vibe (same as a Toyota Matrix) is going bad . Can I just disconnect the rear wheels from it and convert the car to front wheel drive? And save the cost of having to get a new differential put in?

You can remove the driveshaft on a Saturn vue, Chevy Equinox, Pontiac torrent with no issues. Folks complain that the rear ends sometimes bind on dry pavement and the issue is a failed clutch pack. Some say the diff is noisy during AWD operation which may or may not be the same problem. If your diff…

You would have to pull the driveshaft to the rear differential to disconnect AWD. To keep the differential from still turning and possibly making noise, blowing up, ect, you would need to remove the rear CV axle shafts as well. Unplug the electromagnetic clutch for the rear diff.

How do you know it won’t be okay to just let it fail, and hope the result will be simply the loss of rear drive?

'Cause the differential will continue to turn unless they remove the axles and driveshaft. That’s how the system is laid out.

Thanks everyone, I’m hearing a difinitive answer: we need to replace the bad differential. Thanks for making that clear!

what is your failure mode? noise on dry pavement or when wheels are slipping and making the rear “work”? is it quiet during most driving?

So not really possible to just lose the rear-drive portion and end up with the wheels turning freely? I was thinking of some of the crude trailers I’ve seen made from the back half of an old pickup, with the differential still intact.
