98 1998 Toyota 4Runner U Joint - Driveshaft & Axle - GMB, Front Shaft All Joints, Rear Shaft Rear Joint - PartsGeek

Is this a joke.

Here's another interesting thread I just found. Can't take out U-joint

I don't see a replacement inner ball PN anywhere

Here is the most useful thread from the other discussion, just to tie this all together...

Double Cardan joint - Tacoma World Forums

And another good one, same question: '85 Front CV centering ball question. - Pirate4x4.Com : 4x4 and Off-Road Forum

Still no PN for a replacement center ball...

I was able to find this from one of the forums for the ball.

I'm not suggesting that you do away with a DC driveshaft. I'm suggesting converting it to a common DC driveshaft that uses Spicer 1310 ujoints that can be found in ANY auto parts store in the country. Complete rebuild kits which include the centering ball and spring are also easy to find.

I'm going to have to bust out my driveline books and find a CV flange that will bolt to the tcase output flange. There are all kinds of junkyard donor possibilities.

Nice, though in one of those other posts someone said that Neapco bearings weren't very good. That's just one person's opinion, so take it with a grain of salt. If it's well greased, I can't imagine it'd fail that quickly.

I went through this recently too. I ended up getting a new driveshaft built with a 1310 style dc joint and the correct Neapco adapter flanges. I posted a bunch of info in a thread called "Rear driveshaft help". If you search for that thread you may find some helpful info.

When I went through this recently, I was told that the round tube portion of the toy driveshaft is a metric size and wall thickness, so a common 1310 dc will not fit properly. Dc's have a "slip" fit, where they slip inside the tube, then get welded in place. It could probably be modded to work, but the shaft may have major balance issues afterwards.

I post a few links in this thread. You can click on them and find all the parts you need. I even posted a link were you can buy replacement parts for your Toyota shafts. Last I checked they had all the parts you need to rebuild them, and they might even have u-joints.

These are the guys that High Line says Neapco buys from. He says its not high quality. But I wouldnt know. Im still looking for low mileage local part. Seems to be best option right now.

Nothing is high quality compared to High Angle. They're the best, nothing else compares.

EVERY yoke end on a driveshaft tube is a tight slip fit in the tube and welded in place, not just DCs or Toyotas. Tube can be turned to open up the ID or ends can be turned to change the OD to fit inside another size of tube. There are also 1310 yoke ends (both DC and single cardan) sized for metric tube.

It wouldn't have to be based on the Toy driveshaft either. As long as you have the right ends to attach to the tcase and rear axle it doesn't matter what's between the ends.

I worked in a shop that built driveshafts for everything from shaft driven motorcycles to mine dump trucks when I was in college, so I'm pretty familiar with the workings of them. We didn't balance driveshafts either. We eliminated runout and balancing wasn't necessary. Balancing is quick and cheap for assembly line purposes, but it's not the only way to eliminate vibrations.

Agreed... with all of it. I have built/shortened/lengthened a few in my garage with shop tools. Anything is possible with the right tools. My only point was if the intention is to simply put a 1310 dc on a toyota driveshaft (like what many Jeeps run), it is not as easy as it sounds. I asked about machining the yoke and/or the tube to match, and the driveline shop didn't like that idea because of the questionable material thickness on the toy shaft. Also, it was cheaper for me to get a whole new driveshaft with the toy-to-1310 flanges on both ends.

Wonder if Tom Woods can just custom make one for you. I thought their prices were ok considering the quality.

They can, it will be $450 with the correct Toy flange adapters, and you'll be able to bolt it right in. I had a driveline shop called Quigley 4x4 build me one. They are local to where I live so I could pick it up when done. They will also ship though. Let me know if interested, and I can get you in touch with the right person at Quigley.
