It’s cheaper to run unit bearings unless you want to keep the truck for over 400k miles.Although this is interesting I am curious as to what the numbers are.
First, how many miles do we expect to own the truck? 100k, 250k 500k+?
The next most important question is how often do the unit bearings fail and how much do they cost?
And finally, how much does the Dynatrac kit cost, how much maintenance is required and how many miles will it last?
I am all for performing valuable modifications or upgrades but the numbers tell the truth and I am curious to see some. That way, if my unit bearings fail at some point in the future Dynatracs might or might not be a consideration for me. Your thoughts?
But you can service the hubs with the wheel still on the truck and it does increase fuel milage. Admittedly about .5gal/mi though.
Free spin kits also reduce wear on front drive train components.
Yes thy are expensive, no they do not pay for themselves over unit bearings, but I think they are worth it.
