I would like to make modify my front drive shaft and install a long travel slip yoke. I think I have all the tools, just don't know where to get parts (the male and female slip yoke end) and part numbers. I have heard of some ppl just using a standard spicer part number application, but no one mentions what part # they use. Anybody have any advice? I have seen some offroad shops offer a kit for like 250.00ish. I would like to see if I could do better than that if possible.

Well I could do that, but I thought it would cool to build my own just for kicks since I have never done it and maybe save some money at the same time.

If you're not going to run it on the road at speed (think snowy winter), you could build it out of square tube.

We harvest parts from other shafts, some (like the 80 series front) have longer splines. Why do you need longer spline, shackle reverse?

I have a long-spline kit in my front shaft, made by a shop and balanced as good as they could get it. It's ok, but you can feel it if you have the hubs locked and in 2wd at speeds over about 45mph.

I like to do a lot of things myself as well but I'll draw the line at drive shafts and let the professionals do it. The piece of mind alone is worth the cost, not to mention not having to put up with the vibration or worrying that it would shake something else loose.

down in a hole.
if you have a lathe, then, grind on. if not, then consider paying the DS shop to build it for you. I shortened my fj62 front shaft at home, but it does make noise over 35-40 in 4, and due to its homebuilt nature, is small cause for concern. I have not tried to get it balanced yet, and am not too worried about it coming apart, but for the cost vs. time/energy; the DS shop isn't too terribly expensive...

Some good information in these links.

The hardest part is getting the shaft to balance properly. Without the proper tools I have not been able to do it. Mini stuff tends to have a longer slip than a 40 or 60 shafts. I have seen mini shafts be long enough, and sometimes not long enough. It depends on your setup.


Concerning spicer parts. Stick with Toyota.. The comparable joint size in spicer stuff is 1310. It's dimensionally almost exactly the same as a toyota joint except, it's considerably weaker. Whatever long spline kit you come up with, stick with the toyota joints. They really are that much better.

Have only gotten lucky a couple of times, most all homemade shafts are not going to be concentric/straight enough to balance. Best just to plan on them only being low speed, if you need high speed have it pro made.

Agree 100%.
