    **UPDATED** Drop block install tutorial **UPDATED**

    hey guys, this may sound dumb but im gonna be installing my drop stuff this weekend and im doing my last minute research..

    does anyone know of a tutorial for installing drop blocks in the rear or where i can find pics of the install process?

    i found the tutorial on drop spindles which is really cool but just wondering if anyone took the time to take pics of a block install...

    -Steve

    p.s. wish me luck!

    no science to it.

    Lift up the truck from the ass and support it with jackstands.

    Lift up the differential with a jack and set it on jackstands just to get the weight off the springs.

    Now's the time to spray the living shit out of the u bolts and nuts with penetrating lubricant if they're rusted. If they are call it a day and let them sit overnight.

    If they're not see if you can break the nuts loose and if you can remove them and take off the u-bolts.

    Take your jack and place it under that side and start jacking up the differential until you can slip the block between the spring and the spring perch.

    Put the new u bolts on and tighten by hand

    Repeat for the other side.

    Put the diff back on the stands and tighten the nuts.

    Now's the time to bust out the grinder and cut the excess of the u bolts

    Set the truck back on the ground and give it a few spins around the block.

    Come back and lift up the truck and if you have some ramps put the ass on them and retighten the nuts if necessary.

    Voila.

    3 hour job at the most if its your first time.

    where can i find the torque specs for the blocks?
    also, you said "Put the diff back on the stands and tighten the nuts.".. when did i "take it off the stands" lol

    and will the blocks like "snap" into place or is it just a "center it as best you can" type thing?

    I'm nmot sure about torque specs. But as for centering them there is a hole in the bottom of the block and a little pin looking thing on the spring. The pin on the spring goes in that hole. In top of the block there is another pin. It goes in the hole in the mount on the axle. You just set them all down together on the spring then put your u bolts in and tighten them down. You will see what I mean and understand when you get it apart. Its not hard to do at all.

    you are holding the leaf spring up with the jack when you put the block in between it and the diff

    Chassis tech is an aim industries brand which are known for selling garbage. Belltech is better .

    this means that the shop you went to is a low end shop that sells AIM and not belltech.

    BFH and a fork. You can rent the fork set from advance or pretty much any other parts place.

    You can buy a set of spring compressors for like $15 I got mine on sale locally for $10.00 look for these at a discount place

    To seperate the ball joint I use a BFH and hit the side of the control arm until it pops out. I find using the fork things will wreck the boot on the balljoint then you have to get new ones.

    A lot of times the fork will trash the balljoint. I just smacked the lower control arm a couple times with a 4 lb hammer and they popped right off.
