I came across this today and thought it was funny.... at 7:35 when replacing the axle the mechanic hit a "rough" spot and resorted to a ball ping hammer to insert the axle to the differential housing. That didn't work so at 8:59 he resorts to "Wilton" his 3 lb sledge hammer! I was able to easily slide my axle splines in and have them click without using near this amount of force!

Enjoy!

 

OMG ......... Hope that H3 didn't have an aluminum housing......... Torque wrench?
