The boot next to my wheels is broken and leaking. is that a CV boot or joint boot? do i just need replace the boot or i need to replace the axle? do i need to take out the brake disc when i replaceing the axle or the boot? thanks

 

The CV boot is the rubber & the CV joint is inside that. Your better off replacing the whole axle since you have it out any way. The axle nut usually needs a 3/4" imact gun to break it loose, or a long ass pry bar. You do not need to remove the brake rotor, only move it some.

 

if ur gonna do it urself u just need to get the new axle or cv boot if u want to only replace the boot, break off the hub its a 34-36mm socket so pretty damn big u can buy special sockets to get it off at like autozone or checker, then take a lifetime warrantee socket wrench and slip a long hollow bar over it to add more leverage and try to break it off, u may break ur socket wrench thats why i say make sure its got a warrantee so u can get a free replacement if needed, once u do that remove everything holding the axle in pull the brake assembly out of the way and pry the axle free, if ur putting on a new boot u slide it on from the inside if ur putting in a new axle u just slide it up there and use a soft blow mallet to make sure it is properly placed, then reinstall everything, u will also need to lift the car up after u break the hub free and will need jackstands but this is common sense. gl
