It's called a double u-joint centering yoke assembly. I just replaced one a couple of months ago. Got it at Parts America but now they don't have a listing on the web site. It seems to me like it was just under $50 for the ball and flange. Have to buy the u-joint seperate. They will probably show a listing for the entire assy. and a repair kit. But when they look it up more than likely they will only have or be able to get the kit. A few years ago I bought one for a 79 F-150 4x4 and got it at a welding shop. I think that they had the entire assembly.
yea i found it on bronco graveyard and they listed it as "cv head, cv head ball, & spicer spring" but i got a buddy that works at advanced auto parts that knows these truck real well and we were able to find one in town. for the flange, ball, spring and u joint it was just under $60, then with his discount i got it for $43. needless to say truck is fixed and no more vibration.
OK, so how does the ball come out?!?!? I have mine apart, and a rebuild kit on the way,,,,, or do I have to buy the new flange to get a new ball? Mine is in good cond, smooth moving, should I do it, I am of the mind that when you have it apart, do all you can to it.
um the ball came out of mine when i replaced the first u joint. the new one i got the ball didnt come out, although i didnt try to hard to take it out.
Mine would not come out, it was still tight, and the needles looked good, so I put all new u-joints, lubed er up real good and put it back on the truck.
I am told that rebuilding CVs are a bi aa ee tt ch. I don't bother trying to do it, I just find a shaft with a good CV and run it instead. A driveline shop will install a new one for ya, for alot less headache (but more money) than trying to do it yourself.
Previously mentioned, if your shaft is out of balance, you can try to balance it yourself with a couple of hose clamps. Another trick I have heard is to drill a hole in the driveshaft and add a couple of ounces of ATF, and weld the hole up.
