Reply to "Spicer half shafts"

No, Goran- I've never seen an actual a broken half-shaft either OEM or Spicer, just broken u-joints. I have one OEM halfshaft in my garage (not off my car) that has twisted splines from what I suspect is from high-rpm drag-race starts with gumball tires, so the two halves will no longer slide in & out freely, but it isn't exactly broken . I suppose if an inner u-joint broke at very high road speed and the driver was paralyzed by the noise for a few seconds before he gets the car stopped, the innumerable impacts against the ZF & other parts could break or severely damage a halfshaft, but thats only my speculation. Frequent inspections of the u-joint caps for a shiny circle under the snap-rings is a sure sign of the cap rotating due to siezure of the needle bearings. Red rust at the seal area of the cross is another sure sign. U-joint breakage soon follows. Greasing such a u-joint does nothing to prevent disasterous breakage, as there's flat-spotted or missing needles inside the cap & grease won't replace missing metal.
