Unstick caps on driveshaft ujoints

I got the axle end replaced in about 50 minutes. But the tcase end would not even budge the caps at all. I used the socket hammer method. So what are your tips for loosening these suckers up. It's already a lot smoother than before so I may have taken care of the issues. I was getting some light vibes and weird noises. And a regular clunk. Everything is gone except one clunk now. Still not sure the cause but I have gone through about everything. Sye and cv are coming soon hopefully. Got a few little projects first. Anyways let's hear some tips.

I've never used anything but the bench vice/socket/BFH method, but I have seen some posts that mention a U-Joint Press from Harbor Freight.

Yeah. I don't like buying tools and spending money I don't need to. In my experience I end up wasting money. haha. I read those too however. Haha. Someone mentioned a torch. I think my biggest issue was the shaft was rocking no matter how I set it. So I was loosing some force. Because it pivots both ways on that end. So I need to dig my bigger vise out. I was using my smaller one today. I could possibly spray with a penetrant but I don't know how that could affect it I somehow managed to get some inside one of the caps when reassembling. I guess I could just clean afterwards. But this sucker is tight. 12 years did its work. Haha. It will prov be a while til I get time as weather to work on it

You gotta use a bigger hammer. I used a sledge hammer for mine. Made it real easy.

haha I would have but I had to hold the socket with one hand while stabilizing the DSwith the same hand and hammering with the other one.

I am in the middle of a physics course right now, and work=forcexdistance, so if I want the cap to move x amount, I need work/x amount of force. work also equals the change in kinetic energy, which is 1/2mv^2. KEfinal-KEinitial. so basically I need more kinetic energy to move the cap down. since mass is just mass but velocity is squared, you get more energy, aka more work, aka more force though and increase in velocity than increase in mass. I figure I can swing a smaller hammer faster than a big sledge with one hand, so I stayed with the heaviest hand hammer I had.

good explanation for why I didnt use a big hammer huh^

however I think a BFG sledge would do the trick if I can find a way to set the DS and socket up. I wish I had a younger brother or something... hahaha.

I gota wait for a nice warm day (above 35) that I don't work or anything to tackle this sucker and try out the BFH idea.

Yea I clamped mine in my vice on my workbench, held both hands on the sledge hammer, and had the socket balanced there. A few whacks and I was good to go. I hate working in the cold too. I have a heater for my garage but my floor is so badly cracked a cat can fit under it. All the heat just escapes.

My larger vice is hiding somewhere in my garage. We have the tractor and the cbr in there as well. As too much other junk. But yeah garage is only half finished so half insulated and not heated except a space heater. I don't mind cold but I like it at least close 40. If I can find the other vice I can def use the sledge hammer. Haha. Should be fun.

I would highly recommend using a press or a screw-type tool. However, before I picked up mine, I used just hit the driveshaft itself, just below the joint while it was securely in the vice. The caps would pop up & out on the 3rd or 4th hit with a hand sledge. Messing with the socket was always a pain.

I have heard too much about bending the ears in the yoke with a press somehow. I buggered my one piece up because of the cap hitting it anyways. Not bad but enough. I'm Gona try a hand sledge and socket when're I get to it

Penetrant. Then after hitting with a couple of smacks, turn the collar to the opposite side and strike again - should come right out. A 3lb sledge hammer helps too.

Haha two of four caps out. The issue I was having was keeping the shaft still because my vice was too small. I found y bigger one but couldn't attach to my bench. So heres my rig actually I have had trouble removing the shaft as well because it gets bound up. I need sye and cv within the year. Went from little hammer to middle sized hammer this time btw.
