Can I get some advice about 'diff' lockers?
What type are there? (Automatic, air-locker,...)
What are the advantages per type of locker?
how much cost it (approx)?
Can I installed it myself, or do i need a welding machine...
Is one in the rear enough or is it better to mount it in the front axle?
For my sam,I would like a diff that i can manual lock and un-lock,
I use my sam as daily driver, so it has to deal with on-road but also with mud, ice&snow, ...
AND I only want a locker that is proven by the control,
it should be a legal solutions (so no welding on the axle etc...)
