D35/44 U-joints

[motopete]

I was calling around for u-joint prices and found that percision joints are greaseable. Which makes me wonder why everbody says the spicer 5-760x are the joints to get. I would think that a greaseable joint would be prefered. Tell me what I'm missing.

precision have always done right by me.

Greasable joints have hollow channels to allow grease to go to the caps, therefore weaker.

the spicer 5-760x u joints are an upgrade from the stock 297's. Look:

"These joints are an updated design and have a cold-forged cross which has repeatedly been shown to be much stronger than the 297's hot-forged cross, with a much longer fatigue life. This should help to further put the brakes on broken u-joints.

I have found this cross is next to impossible to break, the needle bearings in the caps generally will crush and disintegrate before the cross itself fails (that is if the splined end of the shaft doesn't twist off first)."

Also, just because its greasable doesnt mean its better. A sealed unit is much better than a greasable u joint that doesnt get greased as often as it should...not to mention the hollowness of the greasable units. Get the spicers, theyre cheap insurance.
