As a minimum, make sure they weren't made in China. Their metallurgy is highly suspect. Near as I can tell, you can't go wrong if they are made in the good old US of A.

some have grease fittings.
Which is both good and bad. It makes the easier to lube, but it puts a hold in them what kind of power are you making? |

I went with the Spicer solid joints, 579X is the part number if my memory is working. The greasable joints are slightly weaker and you would never get a grease gun in there to the zerks again anyway.
Oops- bad part number, bad memory. |

If the zerks were on the end of the ujoint cap, would it clear when rotating?
Yes it would be tough to grease some of them because the aluminum yokes are fatter than steel. But I honestly haven't tried. The outer ones are half buried in the knuckles. Wtf does kragen sell for $40? Everything they sell is from China. |

I don't think you'll have a problem either way John. My factory pieces lasted 80K and 20 years before the lube ran out. Normally I'd recommend the greaseables if your car is street driven and going to be on the road for at least another 10 years. |

John, rockauto sells the ac-delco ones with the coating for cheaper than the parts store.
I don't know who their supplier is though. Cost shouldn't really be a factor on things like this that are replaced at >10 year intervals. |

I use a long 2 x4 horizontal across the camber bolt mount levered against the frame Think about it; the halfshaft is between 2 fixed points with the uni caps seated in the yokes. You have to be able to move one of the points to get it out Usually the uni caps are frozen in and need a tap to crack loose. |

The new u-joint caps are somewhat snug on their own. But it's not a bad idea to tape or zip tie them in place until you're close to bolting em in.
btw, there's only one size half-shaft joint for all C4s. So don't let the counterjockeys tell you otherwise. |

Alright, that job is done, not as bad as all that. actually, I made more out of it that I should have.
Trouble is, the vibration that I've been chasing is not gone. The noise is gone so I'm good with that, but the 73 mph + vibration is still there. Could it be a bearing in the rear end. |

It shows mostly in the front Driver side fender but doesn't feel like the front wheel is shaking. I've been chasing this same wobble and have had three different set of tires....... I had the wife drive the car down the freeway and I trailed her. I was looking for a visible wheel shake....and nothing at all was visible. I'm thinking it is still that half shaft. Understand, before it was really moving around up in there. Now it is quiet, so I have not ran it on Jack stands to watch again. But I'll jack it up again in the morning to see if I can get it to shake again while on stands. |

If it is coming from the front DS that's the first place I'd check. How is the suspension up there? Ball joints, etc.
When I had a bad u-joint in my xterra, the whole truck would shake on acceleration over 45 mph, it wasn't limited to one particular area. Just a thought. Matthew |

My exact thoughts as well. but to note, I only have one half shaft left that doesn't have new u-joints. The Drive shaft has u-joints with ~10k miles maybe.... This side u-joint or half shaft (passenger side) was moving up and down about half an inch when I spun it while trying to find the clacking noise originally. I felt like the u-joint change would fix it. It did as far as the clack clack clack goes. The fact that the wheels are not visibly shaking leads me to believe that the vibration is somewhere besides the typical bent wheel. |

Exactly. So When I got this last set of new tires, I had them put the wheels on the balance machine by itself. No visible wobble in all four of the wheels. I used to work in wheel repair http://www.wheel-repairs.com/ So I think (really, I'm no expert) I could spot a bent wheel, but who knows I may have missed it. But it is like that thing when Trouble shooting some MS Windows trouble -did this solve your problem? -No, I'd like to try something else at this point, I'd click "No, I'd like to try something else.

Bad shocks just won't cause this problem.
Maybe you did check, but did you check all the wheel bearings? And rocking them back & forth at 9 & 3 can check the tie rods. |

^^Front or Rear? Or both?
I've replaced the LR bearing as it was bad. The RR bearing has no play...I've wobbled it all directions and other than the slightest slop it seems ok. I may be wrong. So jack it up and stress the wheel at 9 and 3? Am I looking for "flex" or all out slop? We've used large Screwdrivers when aligning the wheels to see if we could find anything loose. And the only thing was a Rear Dogbone.....but whether it was bad or not was questionable amongst the techs at the alignment shop. |

Some signs of wear.
The RR tire wears very quickly....I'm thinking that it was due to the U-Joints. The Right Front tire seems to wear on the outside only, despite three times on the Alignment rack. The Left front wears OK yet the fender portion of the clam shell above it shakes. The RR tire with the questionable Dogbone wears fine as well |

Both front & rear. You can get the best indication of wheel bearings at 12 & 6. When you go back & forth at 9 & 3, watch the tierod ends, everything that connects to the front spindles/rear bearing carriers. It's easier with 2 people. On jackstands, doing this, does the dogbone move at all? Flex vs slop is a tough call, you'll get a little flex with the rubber bushings, especially if their old but I'd think slop (like tierod ends) would be more likely to cause the problem. But, if everything's reasonably tight, it's something else. You eliminated the u-joints and have a good feel for the wheels. You could put a dial indicator on the wheels, both ways, bead lip for runout and on the inner edge for out of round, but you probably already know this. IMO, at 73, wheel balance problems start to go away. BTW, everybody's dropped the u-joint caps at least once. They even make a rubber tool to hold them on. |

Well, I won't discount old suspension parts as the culprit. I recheck the Tie rods. I just figured the wheel itself would be visibly shaking if so.
And why did you mention the u-joint cap thing? I'm pretty sure I got all the caps in place the first try. There are ears on the yokes that the caps have to fit inside of before the straps go on. I'm positive I hit the mark on all four accounts. Only one gave me any trouble. |

^^oh yeah, did that in 1980 with my Cutlass Supreme.
Not only that, I allowed some of the pins to fall over while pressing on the cap.....they indented the inside of the cap as I hammered the shit out it trying to get that last .060" so that the clip would fit in the grove. after hours of labor and destroying u-joints, You'll only ignore that once. Back on topic It has to be the RR Wheel bearing. That or the pumpkin. I think the gears inside are rubbing/clanging together. That or the coupling bearing between the T10 and the Nash overdrive has come apart.... The Drive shaft is rolling smooth, even at speeds...but the rear end still makes that rack rack rack sound and the half shafts sort of jump. The drive shaft does not move at all......it is spinning nice and smooth. |

What part of the right halfshaft is moving up and down? Diff or wheel side? Its sounding like a bad bearing to me.
Make sure you don't have the parking brake on when checking the bearing play. Was the bad LR wear due to that completely shot bearing that was replaced? If so it shouldn't be an issue now. BTW I have 2 bearings that are still good, I pulled them to install the tapered rollers. Either are yours free if you're in the area. |
