New axel work 

My truck originally had 355 gears. When I had the stock 351 M motor with 200 HP pushing 40 inch tires I decided to go with 456 gears. They were great out of the hole but slowed me down on the hiway so I changed them to 389 gears after I built a new 400 block engine with 450-480 HP and 400 lbs of torque. Then one day I snapped my rear axel. So that's when I decided to completely gut both axels and do them right.

I purchased and installed a new Detroit carrier & Strange case cover for the Ford 9inch. and a new B & M differential cover for the Dana 44. All new heavy duty Yukon 373 gears, axels, bearings, seals etc...... were done and all upsized from a 31 spline to a 35 spline axel. I'm pretty sure this will give me a tight drive train and safe ride now with my new engine and 40 inch tires.

Interesting for you
