Hey fellas, i was gonna buy a 6 inch lift to raise my blazer but 1800 bucks,no way. i just found a wrecked 99 jeep cherokee. axles are same width as mine. i am gonna remove all my blazer suspension and replace it with jeep. front axle off jeep also has cable actuated 4x4. am gonna use front coil spring. has any one else done this. i am a welder and machinest by trade . and this just my spare time. any one else done this. i want to run 33x12.50 /15 . gears for the jeep are about a 100 set, and a locker on ebay 100. so i figure for about 400 for the jeep wheels are 800 through summit. so i should have all i need for 1800. and gears i want and tires and rims to boot. any opinions

 

go to s10forum liftin' it section, tim99zr2 did exactly what you want to do. SFA swap and made pretty much everything from scratch.

wow . alot of info .. thank you. this is just what i want to do. perfect. thank you

 

With a cursory look over that link, it provides a lot of good information, but one thing it leaves out is the proper alignment of the caster which is set on an axle when pinion angle is set. Unless you get an axle built for your specific intended pinion angle, you can end up with a very uncontrollable vehicle on the road. Now the other option would be to measure the original pinion angle that the axle was setup for and then what your intended pinion angle would be. Cut off the outer flanges and rotate them by that amount.

The other thing that I would like to point out is that I would have choosen to mount the shackles in the front and the solid mount in the rear. This is due to the movement of the axle during flex and acceleration. With the shackles in the back, the axle will swing forward even minutely, but this will do more to complicate driveline angles that are already pretty complicated. By putting the shackles in the front, the axle will swing towards the back, maintaining better driveline angles as well as cause less of a length change in the front driveshaft. The impact of this will be more pronounced the higher you go.

Another good article at Offroaders.com is the one on shackles: Shackle Length and Spring Movement - Offroaders.com

 

i just got the front diff. i got the complete with all brackets. i am going to use the coil over suspension. the guy i got the front diff from has a jeep with the rough countr 6 inch lift. the way it is built i can copy it so i can adjust the angle of the diff for the caster. all i will need to buy is longer coil springs and some tubing to mount the shock and coil. he also had 4 real nice 10 inch rims to fit the front diff. i will have to get spacers for the rear but was planning anyway for the offset. am looking at a set of used 33 for the truck. the rear i am just gonna do a spring over. then buy matching gears rear and front . i am gonna drop to 4.11.
