i hoping to get this stickied since i had a hard time trying to figure it out on my own.. i know that it is a couple of bolts and all but pics and a how to thread should be helpful to clear up all the confusion for people that want to do this in the future
ok first start with getting the truck off the ground. support the rear by the frame if you dont have a lift of any kind... and then remove the rear tires.. i hope everyone that does this knows how to at least do that part.
ok well some basic tools to do the job
1. metric and standard wrench set
2. a torque wrench
3. PB blaster or liquid wrench penetrating oil
4. an impact gun if you have one
5. set of belltech shackles
6. a jack
here is the difference in stock shackles and belltech shackles..
also these can raise the rear end up to 2 inches or 1 inch.
then remove the lower bolts that keep the shocks in place
next support the axle with the jack, just put the jack under the diff and jack it up to the axle and lift it just a little bit to get the weight off the shackles (it makes life alot easier)
and now you can get under the truck and see needs to be removed
next remove the bolt that holds the leaf spring in place and then unbolt the shackle.
when you unbolt the shackle you will find this wierd looking nut behind the shackle.. you will need to find this to put the shackle back in place and keep it tight.
next install the new shackle and put the bolt back in place and you will have to feel with the nut to get them to line up. get the bolt tight but not to torque specs at least not yet. and then insert the leaf into the new shackle i just used my hands to lower the leaf in place and then slipped the bolt through it to hold it in place. If you have to tow package dont slip the bolt all the way through cause you have like a inch to play with on the other side to get the nut on cause the tow package gets into the way.
then put the nut on the leaf spring bolt and tighten it down to 75 foot pounds of torque. and then do the same to the shackle bolt up top. and then repeat on the other side.
and here are some before and after pics of my truck
I did run into a couple problems when i installed them cause i have the tow package i had to remove the hitch and all because the lower shackle nut was getting into the way and causing it to rub and affect the downtravel of the suspension.. so i just removed it. but if anyone has a fix please let me know cause i want to install the hitch again ASAP!
