Neilda, no with the standard hub, bushes and pins you will always need to grease, ever 500 miles is an idea, but it only takes 2 minutes anyway, so hardly a chore. The new front suspension kit uses the standard hub and kingpin, it is the SUPLEX springs and tuned Bilsteins that give the improved ride and roll stiffness.
There are materials, seals and bushes that increase the period between greasing and ultimate life up to over 100,000 miles in some cases. Regards PJB
