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 step, we're going to talk about the proper method for seating our new drive shaft or constant velocity joint into the splines on the hub assembly. Now all we're going to do is get it started through the hub and spin the nut on just a couple threads to hold it in place. You're not going to want to tighten it all the way down at that point, you're going to want to seat the ball joint first. So only a couple of threads. What you're going to need to do is pull the hub out just about as far as you can, taking care not to overstretch your brake hose if its hooked up. That's about all the tension you want on a brake hose. Anything more than that may tear the rubber or damage the internal tube. Once you have just enough space you can take and slip the constant velocity joint stud into the hub just like so. You're going to want to wiggle it around until you get the splines to start seating and then you can start your new nut. Now that I have it aligned and pushed through to expose enough threads, I can start my CV joint. I'm going to go ahead and do that now. And like I said, you only want to put a couple turns on it right there. That is the proper way for seating your new drive shaft or CV shaft into the hub and starting the nut.
