Learn how to install a drive shaft into the transmission in this free auto repair video.
In this clip, we're going to talk about the proper service procedure in order to remove and replace a broken CV joint also known as a drive shaft on a front-wheel drive vehicle. In this clip, we're going to talk about installation of our CV joint back onto the transmission or to the mid-shaft bearing. We're doing the passenger side and on this particular vehicle, it has a mid-shaft bearing. Being that the transmission is located on the driver?s side of the vehicle, it has a small stub shaft that runs to another bearing. You may or may not have to. It?s pretty uncommon to have to switch the seal over. The new drive shaft as you can see doesn't come with one and this just pops off the old one like so. That's how you slide it on and that's how you would slide it off. What I'm going to do is take and help and extend the life of that bearing, I'm going to pack some grease in here. What that will do is add to the lubricate that is put in at the factory and help keep water out of it. Just like so. You don't need a whole bunch, it is a rotating item and all this grease will get spread around in there as you drive the vehicle. I'm going to go ahead and take and slide that on now just like so. That there is the stub shaft and mid-shaft bearing coming out of the trans just getting the output energy a little closer to the drive shaft. What we're going to do is take and line up our constant velocity joint with the splines on that and pop it in place. This is the portion of the CV joint that we're going to line up with the stub shaft on the transmission. Just going to take and align it and get it as straight as we can. The straighter it is, the easier the installation process will go. Once you have it started on the output shaft of either your trans or mid-shaft bearing. It may be necessary to tap it on with a hammer, but you're going to want to make sure you have it stated on there first so the splines are lined up correctly. If you have them misaligned, they will damage each other and the shaft will fail to seat all the way. But once you have it lined up and as straight as possible, you may have to pull the hub back out of your way and drive the shaft on. And there you go. That is the proper way to seat your drive shaft in the transmission.
