1st yota purchase. 98 runner. can i put locking hubs on to increase mpg. are asian better than warn?. any low buck leads? thanks dmcdano

 

Theoretically...yes. Actually...No

Do a search this gets discussed from time to time

 

Nobody has ever shown me a data set where I could statistically say manual hubs helped mileage. There is enough variation tank - to - tank in real world driving that it's not right to just compare the tank before the swap to the tank after the swap for example.

It costs about $1000 to swap your '98 over to manual hubs BTW. You have to convert the front end from semi-float to full float.

there are some good reasons to switch to manual hubs (CV wear, trail breakage options, etc) but gas mileage isn't one of them...

 

aisin is better than warn
