I own a 2000 2dr 2wd blazer, this is my first car, the owner befor me lowered it 2 inches and i need help returning to stock.

THE REAR: 2 inch blocks i think all i have to do is losen the U bolt and jack the axle off the block then remove the block and then tightin it back up. if im wrong please tell me.

THE FRONT: the owner befor me installed a after market part to lower it. my problem is i dont know what its called it had a inner circle with 3 arms sticking out and at the end of the arms there are holes for bolts.

I have pictures of all thease things but dont know how to attach them

 

correct, by removing the rear block it will raise the vehicle to stock, and the item you are talking about up front is called the spindle.

 

will it be easy forto replace the stock spindle. i know very little about suspention stuff

 

it shouldn't be too hard but when you do take replace it to stock let me know how much you want for the spindles. i'm looking to drop mine and spindles are the best way to do it. (IMO)

You just need to buy a stock spindle which i'm not sure how much it would cost. you could probably junk yard it
