Review on Yukon Gear YY GM40015850 Differential by Alfredo Testerman

May not fit your car. For the year and model of my van, they list it as a replacement part. After a partial installation I realized that this part is not good, maybe it is a fake or just not a fully finished part. There is no snap ring stop or bushing to prevent your universal joint from falling apart. This is the correct sprocket size for mounting on my diff but not on OEM station wagons and therefore on the driveshaft. I had to order the correct part from a GM parts supplier. I would suggest if you are looking for one of these to do the same or try your local junkyard. I don't understand how this can work on every vehicle. With no stoppers or circlips to keep the bearing caps from falling out, these are just fake parts.
