Default Removing Passenger CV halfshaft from Intermediate Shaft

I am replacing my CV halfshafts on my 2003 Mazda6S. I am having some trouble removing the CV halfshaft from what I am calling an "Intermediate shaft" that actually connects to the transmission. I already did the driver side and it came right out with no problem. I tried prying it with a bar but there isn't a lot of room to work with under there. In attempting to get it out I popped the inner boot off so I ended up removing the entire shaft to attempt to get it out. Has anyone else had a problem getting this off from the passenger side?

Thanks for your help.

It can be a PITA to get apart. Clamp the intermediate shaft in a vise and use a axle puller with your slide hammer to get the CV shaft out.

You can rent both at AutoZone

Be sure to replace the carrier bearing.

Good luck!

I'm having this problem right now. Driver side was cake (except those damn lower ball joints) I've been fighting this thing for a couple hours. The intermediate shaft is still in the car and the axle separated at the same point. Man, this sucks.

You need to remove the intermediate shaft from the car so you can clamp it in a vise. Then you can separate it from the CV shaft. Good Luck!

It usually isn't very hard to separate them if you give it a good whack with a decent sized hammer. You might not know where it's supposed to separate so here is a picture just in case. The circled section is where it separates. Hold the intermediate shaft up in the air with the CV housing hanging down. Whack the housing down at the arrow location. A whack or two should push it over the snap ring and then it will pull right off. You are replacing the shaft anyway so hitting it with a hammer isn't going to matter.

I ended up taking the intermediate shaft out. It was a lot easier than I thought it would be. After that, the separation was very easy. A couple hits with a hammer got it. Thanks guys.

I'm trying to find a C.V. joint from a Mazda 6 EU model that will fit my 2004 M6 V6. To match the correct part I need to know how many splines there are on the inside of the outer C.V. joint (one that goes into the wheel) of the V6 model, and I don't have a spare one laying around that I could take apart. Does anyone have a old C.V. joint laying around, and could tell me how many spline there are on the inside or could take a pic for me? any help would be appreciated
Here is an example of what I am looking for

WARNING!!! Folks, if you hammer on the Trunnion joint (inner joint) while using the CARRIER BEARING AS HOLDING FIXTURE (IN THE CAR) - YOU WILL DAMAGE THE CARRIER BEARING!!! DO NOT HAMMER ON IT WHILE ITS IN THE CAR!

It will last for a while, but it will fail. Remove the axle and simply hold it in the air as Blackcoog suggests. You have the weight axle to help it come apart. The downside is the inner joint may fall apart. This is only a concern if you're reusing it.

If you can get two pry bars up in the car and apply light force on BOTH SIDES of the joint, they usually come right off. Applying force from one side only usually just binds the clip on the shaft locking it tight.

I'm not sure what your timeline is but most of us don't take the joint apart, just swap the axle for a boxed item. My point; this could take some time for someone to post up the info you need.

I suggest you contact one of the groups that rebuild driveshaft components. Either that or head to a wrecking yard if there is such a thing in your parts.

Good luck!
