After spending years making whatever i had on hand work to get the job done cheaper I'm at the age where I'd rather just have the right tools for the job that make it easier with less frustration; and torque King fits that bill. Most everything is decently priced and being able to buy a given package deal for a particular differential is very convenient. The differential specific manuals are well worth buying and give you tips and alternatives with potential consequences if you don't want to buy a specialized tool for a given step of disassembly or assembly. The only thing i sourced from a different place were axle shaft universals because i just wanted factory non greasable Spicer since I'm not an off roader and want longevity and durability with minimal maintenance. If you already have the cheaper harbor freight ball joint press and expansion kit then you don't need the longer press (even for Dana 50 and 60) unless you want to use tk's universal removal tool. I already had this so i bought the medium lisle u joint tool... Works the same way just by itself.
