Upgrade from 315/80R22.5 to Michelin XZA 365/70R22.5 per Newell:
Coaches 443 (1997) - 696 (2004) EXCEPT 671, 681 and 685 should only require new wheels and tires.
Coaches 671, 681, 685 and 697-775 require new wheels and tires, wheel hubs and fender modifications. (Steerable tags)
Coaches 776-1229 require new wheels and tires, wheel hubs and body modifications. (P2000i body style)
Coaches beginning with 1230 were built with the 365/70R22.5 tires as standard equipment.
So to answer the question asked, a 1998 would not require new hubs/spindles. Just buy new wheels and tires.
Tom should be able to give a pretty good estimate of the cost since he replaced his front wheels and tires to upgrade to the 365/70's a few years ago.
