Post subject:  need advice on rear universal joint removal

Hi all,

I have removed the driveshaft from the rear axle ( orginal 7.25). That was easy. How do I remove the U-Joint from the driveshaft now? I have sprayed it down with parts cleaner, and it does not appear to have any C-clips on the inside of the cups for the U-Joint, although there are grooves. I have a large pipe nipple on one side, and the biggest C-Clamp I own pushing it from the other. No movement.

So, what am I doing wrong? Are there C-Clips that I cannot see on this beast? More force? What gives?

Thanks,

Greg

Look more closely for the C-clips if they aren't there the caps will slide out pretty easily with a C-clamp.

Post subject:  c-clips removed, still not moving

Hi all,

Okay, i cleaned it more thoroughly, and found the c-clips. The C-Clamp still cannot budge this thing. What next? Heat? Better C-Clamp? vise?

Thanks,

Greg

Post subject:  Update: I broke a bench vise.

Hi all,

Okay, I thought I would bring out the heavy artillery. I used my grandfather's bench vise, ( I had inhereted it this spring), and use the pipe nipple with that to squeeze the U-joint. Nope, I broke the bench vise.

I might try to post pictures tomorrow. Right now, I feel like crawling under a rock, and hiding.

I really could use any advise that anybody has. I am shipping out to a country that begins with the letter "I" later this week, and I would like to get this done before I leave.


Thanks,

Greg

I used a hammer and socket. I had a helper hold the shaft for me over the vice, so the jaws of the vice were just wider then the cup, and then used the socket/hammer to tap the cup facing up.

Unless you forgot a clip or the cups are frozen in place, you should have your joints swapped within a couple of minutes using this method.

You broke bench vise?!?!? I have always had success using a 9 inch c-clamp and one socket (from a ratchet wrench set) smaller than the diameter of the u-joint and one socket larger than the diameter of the u-joint. Press the joint into the larger socket and it should slide out. Of course, it takes some effort, and I have bent the threaded screw-shaft on my c-clamp, but it works for me. Try taking it to your local machine shop if all else fails.

I 2nd'' hammer- socket style, make sure the clips are removed & hammer away, should come right out.

Are you sure the C clips are removed? I have had better luck with a hammer and socket insted of a vise. From experience, I cracked a U-joint cap using a vise and there was no needle laid over in the cap. Just keep in mind not to lose your cool while performing this exercise. :shock: If you bend the ear, it will cost you about $20 for another drive shaft and about $100 to get it shortened and balance if necessary. My last experience was not pleasant. :cry:

If the hammer method doesn't work and you don't want to take it to someone, it just may be less headache to make two cuts with a cutting wheel and grinder or hacksaw and pull the center of the joint out, should make tapping the cups out easier.

Post subject:  c-clips

if you cannot get those c-clips out, try using two flatheads, find the opening if the C, and put yout blade on each edge, use one to hold, and one to pound out. I had the same prob, that was the only solution

Post subject:  Sorry, should have reported the solution

I figured it out before I left home for Baghdad. I used Pierre's idea, and cut the universal joint below the cap on both sides, and popped each cap out with a C-Clamp. This way I only had to press one out at a time, not two.

Thank you, Rotozip with 90 degree cutting wheel. Best money I have spent on a tool, short of a cordless drill.
