CV joints, Why they come off Options

Ummmm.....no mention of the use of the gasket in this thread. Uhh...wouldn't the gasket compressing take care of the lack of perfect finish? What am I missing here??

Doesn't the gasket fit in a recess in one of the surfaces? So that the gasket wouldn't interfere with the mating of the flange and the CV?

The gaskets do run in a gap and if inserted properly should not cause an issue. We used a gasket here and I run with them on my car. It was mentioned that some feel these cause the CV to come loose. I suppose this could happen if the gasket prevents proper torquing. Is is a good practice to re torque the CV's after a few hundred miles.

No it would not compensate for an uneven finish. What is needed is steel to steel without any variation in flatness. If the two surfaces are perfectly flat, then the CV to output flange cannot move.

This is very interesting; years ago when I swapped out engines I put CV gaskets on where there hadn’t been ones. I too, had one loosen and detach from the flange (drivers side); fortunately I was going only about 25mph and started feeling the wobble. Minutes prior I had been going over 75...

My question is about removing the flanges from the tranny, I can’t remember how it’s done. If it’s simple enough I’d like to do this when I have the trailing arms out.

Also, are the gaskets mandatory? Been fine for years without them.

I do have a lathe.

Thanks in advance (IMG:style_emoticons/default/beerchug.gif)

I should have mentioned about removing the output flange. There is a 19mm hex head screw that needs to be removed (drive flange expansion bolt). This is straight forward. Remove the bolt and pull out the flange. The oil should be drained first BTW. Installation is the reverse. Insert the flange fully but there is one caution that needs to be observed. When inserting the bolt, insert it slowly and do not push hard. Put it in slowly until it touches and slowly engage the threads. Tighten by hand until it seats without pushing it. The piece it threads into can be pressed out of position and this may cause you some grief. Torque 25 to 29 ft lbs.
