Rear Driveshaft yokes

I'm replacing U-Joints in my rear axle driveshafts.....
I'd like to make sure I get the orientation correct on the yokes on the two ends.
Does someone have a photo of the yokes properly aligned....or at least a good, clear way to describe the orientation?

Thanks in advance,
Marc.

not the best pic, but shows the yokes are inline with each other on both ends or in phase. If you get them off, it will vibrate and you will notice.

Hi Marc,

The shafts on the left are new and from Gordon's 15 years ago so I would assume they are correct. The shafts on the right side have broken boots and are certainly incorrect.

If installed like the old one on the right a bad shake will develop around 28MPH.
New ones are 50 years old, the U joints wear out after a short time,(less than 3000 miles)
Grease after every swim!

I don't believe there is ANY way to effectively lube those cross point U-joints. Even the late style, with zerk fittings, are very unlikely to lube all 4 caps since the grease will always follow the easiest way to get out and is very unlikely to make it's way all around to get all four caps lubed. Even Hugh knew of this issue and he talked about having some joints made up with 4 grease zerks so that each cap could be greased separately but he never did them. What a pain they would be anyway. That's why I've been such a supporter of using constant velocity u-joints like those that Eddie has made up. These are likely lifetime units and will never need grease unless a boot should someday fail. His design also does away with the center splines wear issue which is also a killer of those shafts. He sells them for only slightly more than the retail price of new shafts. Given that they are likely a lifetime purchase, without any need to ever lube them, they seem like a pretty good deal to me.

Gord,

I'm very impressed by Eddie's work designing and building these shafts. Even though I don't need them right now, I'll probably buy two pair when I have some loose money. Hopefully, sometime soon. Since I've lobbied for someone to produce them for years, it only seems right that I have them myself.

Hi Eddie,

I would be glad to do that. I didn't know you were in the market for my clutches. Right now though I'm low on flywheels and have to find a new source for them but I hope to find a new source within a few weeks. We'll talk more then. Did you get enough cores to keep you going for awhile?

=Gord - i have my shocks off right now - is there a way to determine if they are in need of replacement? - maybe a local shop has a way to test them? (should they test at a certain spring-pressure, etc?)

Eddie - if yours is the Tours-car that did the insane launches, people ought to certainly include your perspective on suspension#%
