whats the best increase in mpg you've seen with new wheel/axle bearings
has anyone seen a great increase after changing your bearings. wheel/differential bearings.
im running 40psi in my tires. my afr's are always around 14.7-15.5:1 i drove mostly highway and low throttle, and i can't get above 18.5mpg. i know my differential is pretty bad. but whats the worst decrease in mpg anyone has seen from bearings.
