Bitchy u-joints

I was trying to replace my u-joints in my dana 60 front today and the fawqers wouldn't budge! I managed to get off all the c-clips that hold them in place, but after lots of pounding and pressing with my vise the caps wouldn't budge! I even went out and bought a bigger vise, but that didn't work either! Anyway, I'm taking them to my buddy's machine shop tomorow. Hydraulic power, baby! But for future reference, is there anything I can do about this in the future? I was thinking that if I was in the middle of nowhere and busted a u-joint, I would be up the creek without a paddle.

having a stuck cap on a busted joint in the field is one of my big fears.

Call me a wack job but when I put my joints together (expec in the axles 'cause they stay in longer) I hose 'em down with WD-40 before I put them in the bore. I then procede to shoot them with penetrating oil when ever I have the ole grease gun out. I even shoot P-oil on the joints in junk I buy hoping it will make it easier when the time comes.

I don;t know if it really works but it seems like I have less trouble getting joints out then some of my friends.....or it could just be that I own bigger hammers..... <IMG SRC="smilies/rolleyes.gif" border="0">

i bought a ball joint press from advanced auto for like 80 bucks... cause i couldnt see spending 250 for one from mac. Even with that and my big fat ass crankin on it in the vice it was a bitch. What works the best is set the fawker on the floor and stand on the wrench for the press. I had to crank it hard about a dozen times before it broke free a bit.

cutting torch, cut the damn things in half to ge tthe cross out and the caps come out easy. Actuall what I've found works better on the forged cross shafts is a big arc welder and big ass electrod, turn welder to highest setting and get to cutting. Works fast and easy its more fun then the torch in my opinin just for the cool factor <IMG SRC="smilies/glasses.gif" border="0"> so basicly once you get that bitch out don't worry about trail repairs, the caps usually spit out anyway and are easy to get out once the cross is gone.

Hah did the same thing today, I got the joints out no problem, then I busted my vice, the whole thing exploded ( 5 foot leverage bar ). Then I proceeded to use my ujoint tool and busted 3 caps. Then I just gave up for the day. I guess I gotta get a new vice. Good idea for next time is allot of <IMG SRC="smilies/beer.gif" border="0"> .

BillaVista --- thanks for that link and the idea. I'm gonna make up a similar tool based on that principle that will apply an optional "tension" to assist the caps in coming out...much like a pitman puller where you tighten the bolt that pulls on the arms real tight and lightly tap the bolt to "shock" it off kind of thing. Thanks.

I had trouble getting ujoints out until someone showed me this. Never had a problem since.

Place the ujoint horizontal cross on top of (not in) the vise (or two closely placed rocks). Then hit the YOKE with a hammer. This will force the top cap up and out of the vertical yoke. Flip and do the other side (s).

This obviously works best for a full intact ujoint.

I'd only use the socket and BFH method (which is not easy to do) if the cross was totally Fogarty-ed.

Thanks.

Damn, and I thought I had described it well this time.

It's not "in" the vise. It more accurately on the vise. Open the jaws just enough to allow you to rest the cross on top of the jaws (the horizontal caps on the jaws..these won't be removed right now) then hit the yoke (this yoke is the yoke that's in a vertical orientation right now- bottom cap is sitting below the top of the vice jaws). Hitting the yoke will pop the topmost cap up and out of the vertically oriented yoke (have had all kinds come out easily).

Then flip and do the others.

Sorry no dig. camera right now.

Is this clear to anyone else? Can you help me explain this?

When I did the front axle u-joints on my 7, I had to resort to a 20-ton press. U-joint tool did nothing. BFHammer and socket did nothing. Those bastid u-joints just laughed at me. <IMG SRC="smilies/mad.gif" border="0">

So I took 'em to a friends place where we could use a press. When I put 'em in there, 2 of the caps blew apart before the joint would move. Even on the press, it took over 10 minutes per joint to get the fawking things out.

You hit on the yoke, it will be vertical (this can be the axleshaft or driveshaft yoke)this forces the yoke down and the cap (top cap) up and out of the yoke.

You hit the yoke -not directly above/around the cap-, but between the cap and the shaft. You will be hitting downward (remember the yoke will be in a vertical position).

bBelieve me it works like a charm.

Sorry Bill.

I never opened your link (just did though), but noticed a reply to it regarding a press of some sort, so I thought that's what yours was about.

I had never seen this method described online or in the mags, always that damn socket and hammer one. That method is useful if the cross is damaged in such a way that you can't rest it on anything.

And the ujoints I've used it on have been over 25 years old (originals) that were rusted to shit.

man 25 years old! What I want to know is how you get your u joints to last so long. I have a 2000 tj and I have already had to go through and change them. I keep them greased and everything. I guess that is why I didn't have any trouble getting them out.
