Front wheel bearings

so I lifted my truck 6 inches and put 35 inch tires on and after about fifteen thousand miles both of my front were fried and of course the dealer warranty will not honor it because of the modification. Im having them replace and its costing around $1400. Any suggestions on how to prevent this from happening again? 2015 Toyota Tacoma

 

I don't know how to prevent something caused by your lift but if U R at all handy U could DIY for $400 and save $1000 about $250 a hour. Don't know about U but I don't make $250 a hour so I DIY.

 

With those huge tires do you also have wheel spacers? If yes how thick?

The only suggestion I have is to remove all the modifications. They are stressing out the bearings.
