keiser31 Posted September 7, 2014 Share Posted September 7, 2014 (edited) I usually set the end (u-joint) on a socket slightly larger than the diameter of the cap and tap the opposite end until the lower cap comes off. Then tap the u-joint the other direction until the final cap comes off. Watch this YouTube video.....

Rusty_OToole Posted September 7, 2014 Share Posted September 7, 2014 Or press them out with a vise or press. I prefer this method to pounding as it is less likely to damage anything. You need 2 sockets for this, one big enough that the cup can go into it, the other small enough to follow the other cup through the hole.You push one cup out, remove it, turn the UJ to the side and it comes out.

Larry Schramm Posted September 11, 2014 Share Posted September 11, 2014 (edited) Some of the cars have a plastic injected to retain the caps. If it has the plastic, some heat on the area of the drive shaft will have the plastic squirting out of a hole and then the cap can be pressed off as explained earlier Edited September 11, 2014 by Larry Schramm (see edit history) Link to comment Share on other sites More sharing options...
Larry W Posted September 11, 2014 Share Posted September 11, 2014 When you state that your's has "just a plug", do you mean a little pipe plug that you can unscrew? If so, just remove it and replace it with the appropriate size grease fitting. If not, just follow the advice above. Link to comment Share on other sites More sharing options...

Larry Schramm Posted September 11, 2014 Share Posted September 11, 2014 I agree, but there might have been something else. Just a thought. Here is a picture of a "U" shaped tool that can be used with a bench press.http://www.agcoauto.com/content/news/p2_articleid/189 Link to comment Share on other sites More sharing options...
