ed xr6 diff question
Hi i have an eb xr8 and I have got on to an ed xr6 diff complete for $450 it has all the tags on it saying its a 3.45 ratio lsd I have not payed for it yet the problem is I can't spin the axles beacuse the discs are rusted and they must be grabing on the brakes. Now I am going to pull the back plate off to have a look inside, what things should I be looking for to see if it is any good? Also would it be more easy just swaping the whole setup in or just swaping the centers. Also if I get the bloke to pull the brakes off so I can spin the axles how do I tell if the lsd is any good????
Thanks for the help
