Sorry for the lack of pictures, I'll try to explain the process enough to make up for it! If I miss something or if you have questions, ask away!
For starters...
Loosen lug nuts, jack the truck up, support the frame on jack stands and remove wheels. It is
very helpful if you have a second set of stands, to support the axle with them.
Moving Forward...
1). Start taking apart the suspension. This is best done by first removing the u-bolts. To do this, loosen the 4 bolts holding them on.
2). Move on to the front eyelet for the leaf spring. Seen in this picture, it is held in by 2 bolts, one 17mm and one 12mm. (It may take some work to make the leaf drop down once this is removed due to age reasons like rust).
3). Head to the back. As seen in this picture, the rear is attached via this shackle, with bolts also removable with a 17mm socket. Once the bolts are undone, the leaf will be able to be slid off of the shackle and removed from the truck. Repeat for both sides.
4). Removing the bushings. The process is simple, but takes some ingenuity depending on age. The bushings
will slide out, but to to age, rust etc. you may need to pound them out with your choice of weapon.
5). Compare old with new! Its just a fun step in the process... I chose Energy Suspension Red bushings.
6). Now is the time to decide if you will be replacing leafs, or simply tidy them up a bit. Mine were in good condition, so all I did was take all my parts and prep them for paint. I also got new shackles, the eyelet and a leaf helper. I painted them using VHT Epoxy Paint in Satin Black to match the truck. It is water, salt and rust proof to preserve your investment
The Re-installation...
Once you have gotten all your parts back together, its time to put the new bushings into place. This is also a simple process, as the new ones slide right in...
1). Grab the new bushing and apply grease (pre-lube).
2). Slide 'em into place!
3). This goes for all the bushings...
4). Once all the bushings are in, lube up the shafts on the shackles as well, and start by sliding the shackle into the bushing attached to the frame.
5). Slide the rear of the leaf onto its location on the shackle, and the bolt it all into place.
6). Next up is the front of the leaf, simply the reverse of the removal process.
7). PAUSE! You may have noticed we never removed the strut. If you are changing out struts, now is the time to do that. It is still attached to the frame via an 18mm nut. You will be removing the strut at this point regardless in order to simplify the rebuild process, but if using the old one, there is no need to remove it from the plate at the bottom!
8). Remove the strut from the frame location.
9). Re-install the u-bolts through the holding plate, and tighten. Make sure everything is lined up properly!
10). Once the suspension is re-attached to the axle, the strut can be remounted to the frame. The axle may need to be jacked up a little to allow the mount to line up.
11). Do a final bolt check, re-attach wheels and let the truck back down!
DONE!
