I use my truck to pull 20ft cattle trailer and want more low end torqu.... If i put 4:56 ring and pinion gears in do i need to change all bearings and bolts.... As axle bearings and seals, pinion & carrier bearing, and ring gear bolts.... Any help for a young farm boy....

 

Not necessary, but you may want to replace the pinion and carrier bearings while your in there depending on mileage.

 

its got a good 190,000

 

Ya I would throw in the pinion and carrier bearings when the gears are being done just for piece of mind. The axle bearings and seals can be done when needed.

 

so i would just need to buy pinion and carrier bearings, pinion shims and of course the gears.... and the front end takes reverse gears....
correct me if im wrong.... plz
