I have a lifted FJ40 that I put a CV driveshaft on the rear from a 4runner. I felt the u joints were bad so I removed the old ones to replace them. When I got replacements, they didn't fit. I went to a local driveshaft shop and they told me that the CV joint is considered a "nonservicable item" and that I would have to replace the whole thing. They said they would sell me a new one for $195 or a used one for $100. I'm here to say that is BULLSHIT. I found a set of u joints for it. I got my set from Napa, they are Precision pt# 513. The driveshaft shop also said they were junk. Would you put crap from Advance or Autozone on your rig? Yes, there are better joints out there, high dollar joints, but unless you're running a big block and 44"s, you're fine with the quality joints from Napa(alloy centersection vs. forged from Autocrap). Would you rather replace a u joint, or a twisted/broken driveshaft? If you put chromoly or other high dollar joints on your truck, chances are you now change your weakest link in your drivetrain from a cheap, easily replaceable part, to a high dollar, PITA part. Don't let a shop try to rip you off, that's why they invented kick-ass sites like this one.
 
First off I'm the drivestaft shop he is talking about.
No sir, not here to rip anyone off!!!!!!

You came to my shop asking if you could half ass your
driveshaft by grinding out the holes in the c/v h-yoke so
you could make the wrong joint fit in your driveshaft.
i told you no.....not a very good idea.

Usually when the c/v goes out... both the joints, and the
centerball yoke have to be replaced. So the price of $195
was quoted to you....EVERYTHING NEW, including labor.

About the crappy joints you bought, if you take a piece of
shit u-joint and put it in your shaft and the u-joint
breaks....you got a 99.9% chance that it's not going to
break only the joint, it will take other drivline parts with
it...(h-yoke, centerball, stub yoke,.....etc)

Different joints have different specs on them, say if you
have a spicer vs. an auto zone brute force, the spicer will
be machined with closer tollerances than the AZ
joint....therefore the spicer with the quailty machined
tollerances will be stronger, & last longer.

I don't understand someone saying they got ripped off
soley based on thier ignorance of the subject.

You don't have to buy our parts.......the info we gave you
was FREE........so don't run around badmouthing!!!!

oh...and yes this is a kick-ass site
 
I don't particularly build anything on my drivetrain to break, but I do run 6 1310 joints in my driveline set-ups. I know that this is my weak link, but although it is the "weak" link, I still use Spicer u-joints. It will most likely break first, but I don't want to give it a good chance in the first place. And by the way, you can get a Spicer u-joint from auto zone; I do it all the time. I'm not even sure where you were going with grinding out your CV yoke.. bigger cap size? More angle? Either way, THAT will be your weaklink. (And an expensive one at that.)
 
What makes a Precision joint crap? The tolerance is tight, alloy centersection, what's the deal? I never intended on "grinding" anything. But when I'm told the CV is a nonserviceable part, that I can't get u joints for it(by more than one source) I felt I was left with honing the parts out, only to be able to more easily replace the joints with a common size if needed. I spoke with a machine shop who has done this before with no problems. He said taking out 0.45 mm was not enough to weaken anything. This is not needed though, because I found the joints. I also found a couple sources that have each individual part of the CV if ever needed. I don't wheel my truck as hard as a lot of folks, it is mostly stock, except for a disc front, chromoly birfs, suspension and 36"s. I drive my truck with respect to the fact that I want to be able to drive it home in one piece, which I've always been able to do. I don't want to half ass it either, that's why I'm researching everything before I go spending unneeded money.
