Can anyone give me some pointers on installing my lift on my ole CJ? Do I need to angle the rearend? I have shims for the back. Any and all info will be greatly appreciated.
 

I'd use the shims on the rear. Some folks don't like to use them but i haven't had any problems with mine. The angle of the driveshaft will be too steep without it, especially on a cj 5. Another option would be to replace the spring perches and clock your rear axle but you'll have to cut off the old ones and weld on the new ones.
 
lots of litheum grease on the bushings, steel sleaves and bolts. it will keep the squeaking down and will make removal years from now easier. I personally do not like shims, I prefer to move the perches. every vehicle that I've had shims on, especially aluminum shims, they split and fall out. plus you generally need more than the 5 degrees the shims provide to properly line up the out-puts.
 

Do one end at a time. lift the jeep up in the air and support with stands, take off the shakle nuts and support your axle with a floor jack, cut your ubolts off and take out the shackle bolts. The end of your spring that attaches to the frame behind the front tire or in front of the rear are a real pain to get out, I have had to POUND many out with a long 3/8 extention or smaller bolt. I like to hang my springs first then lower the axle down onto them with the floor jack. When you lower your axle down onto the springs, there should be 3 holes in the axle spring pad, make sure the bolt on the bottom of your spring pack go,s into the center hole.
 
I'm replacing the bushings in the end of each springs with poly. Do they need to be pressed in? Also I'm having a hard time finding them.
 
They can be a pain to get out. There should be a metal sleeve through the center of the bushing that gets rusted and sticks to the bushing making it tough to get out. I use a large flat head screw driver or two to get them out. Grease the new one,s and slide them in, you may need to use a few taps with a hammer to get them all the way in. quadratec, 4wheel parts hardware should have them, google them.
 

Good deal. Thanks for the info. I found them in a kit with the U bolts at JC Whitney.
 
When you reinstall the new ubolts, tighten the nuts, then use a hammer to tap the top part of the ubolt that go,s around your axle tube from side to side and retighten. Do this until the ubolt will not shift from side to side anymore when you tap it with the hammer. This will help seat the ubolts and require less retorqueing of the bolts after a few rides. You should always recheck your ubolt nuts after a few days then again after a few weeks with a new install just to be safe, because they do shift and settle in. Once settled in get a alignment done.
