Well, it's easy to get off.  I did mine this morning as well. I feel your pain. It's best to do a search, that way you're armed with lots of advice (some good some bad). I usually Google the issue and add the word "Valkyrie", it'll typically lead back here. |

Actually I do have some advice: go easy and don't use any sharp instruments or you'll tear the boot and be screwed.

What are you having trouble with ? The swing arm or the u-joint or both ?
I'm not sure what the problem can be, but, it seems easier if the swing arm is level/horizontal which also makes the boot easier to install.

Is there a proper direction to have the u-joint pointing (front-back/long-short)?

Yes Patrick: It only fits one way. The splines are different front to back: grease the trans output shaft with 3% moly grease. I use Valvoline Durablend. Slide the joint into the sw/arm and insert it onto the shaft. Now the tricky part: I usually put the boot on the engine and work the rear onto the swingarm. Some folks do the opposite and roll the boot back before joint insertion. I've heard of silicone grease helping this along. Using small fingers or long needlenose, : after this statement is the fun part. Put the boot on. Have fun.

I got the swingarm level, then used a broom handle to slide the Ujoint up, gently wiggling the handle and the swingarm a bit and in she went. Similar to intercourse in a dark room.  |

To get the driveshaft into the ujoint, stick rear end in, raise the swing arm up as high as you can, and wiggle the crap out of it.
Should go home in seconds. If the rear end goes in, it has to be in the joint. No room to miss.
This procedure also works for sex, but I'm pretty sure you were wanting to get the Valk back together.

At last its together took a 3/8 30" ext. and lifted the ujoint up and a 3/8wood dowel to hold it up until I got the driveshaft started pressing in and turning it until it indexed with the ujoint then a light tap with a small hammer sent it home.
I hope this ujoint will last longer than the one it replaced (60,000 mi)thanks all. 73 Patrick

Boatnut, your last post has me thinking you put the shaft in and then put rear end on.  If you put the drive shaft in the swing arm and U-joint and then put the rear end on the swing arm, I think you might have a problem. That is a good way to tear the seal on the drive shaft at the pinion cup. If that seal gets damaged, you will be buying a new shaft and pinion cup very soon. The shaft should be installed in the pinion cup on the rear end first and then inserted into the swing arm. Only this way can you see that the seal is going straight into the cup and not getting torn on the side of the cup. Bigwolf |

Bigwolf Yes, what he said..also I hope you had a strap on that swingarm before adding the weight of the wheel |

And next time, keep in mind you don't have to remove the swingarm to pull the u-joint. http://www.rattlebars.com/mtz/ujoint.html |

Bigwolf What he said...if you installed the shaft in the swing arm and then put the rear end on, you probably should redo it. Likely the pinion cup seal is out of place. I demo this at inzane every year...if you stick the shaft in the rear end and then follow the instruction I put (above somewhere) it goes home on seconds...every time. No broomsticks. No playing around. |

I pulled the swingarm befor I knew better,thought I could stab ujoint and then swingarm pivot bolts
I was wrong.
What sort of life are you getting out of ujoints? 60,000 seems rather short. 73 Patrick

60K would be normal for a very heavily used one or one that was over stressed by abuse or poor Assembly/disassembly technique

The one I replaced was from prev owner. I got the bike with 29,000 on it. Replaced it last year at 65,000. Due to it going south on me. Got 15,000 on the new one now. So far so good.
