Dana Spicer 1200I steer axle. Cast iron standard hubs. This is on a 1997 Peterbilt 379 VN437246. Some Dana literature states use an approved drive axle lubricant 80w90 mineral or 75w90 syn. Peterbilt literature states non driven hubs use Synthetic 50 transmission lube. Peterbilt service manager says synthetic 50 as well.
Which is the better choice?
Front hub lube, which grade?
