Free wheeling hubs more fuel efficient?

Post by young-gun »

A mate reckons that if I put free wheeling hubs on my 94 Pajero I will get better millage.
Any truth to this?
cheers

The disconnect on the centre diff means the front axles are turning, but not the crownwheel, pinion and front driveshaft. Manual free-wheeling hubs will reduce the rotating mass a little more, but whether the difference will be noticeable is doubtful.

However, freewheeling hubs give you the ability to disconnect from a damaged CV if you need to, so they're not a waste of time, either.
