I can't find the article anymore that tested greasables as being about 5-7% weaker than solid ujts. If you find it, please link it.
That said, I've run Spicer greasables for 25yrs on every ujt on my K30 with 454/39.5" TSL. I see lots of mud/water, never broke anything. They last a long time but still need to be replaced every several years. I may try the 'sealed for life' Spicers next time.
