Ok, I know tons of you have done this. Show me a few pics of how you did this. Springs under frame or outside? How about the perches over the front passenger side diff? Im getting ready to make this change and need some info.

Thanks,

Hey, I knew the guy that was friends with this other guy that had a brother whos girfriends roomate dated a guy whos Uncle had a nephew that new how to do this, and it was almost impossible. I think the trick is to get a Plasma Cutter, I am sure that you will at least need this to complete the task. Yea, thats it, Plasma Cutter, BFH, Grinder, Welder, and a case of beer.

It depends on the jeep..

On my five the springs are outboarded..

Heres some pictures..





To remove the perches Plasma cutters help, but it can be done with a grinder and a lot of work..

If you look at the front axle in the first picture you can see the housing was ground away to allow a perch, The only thing you have todo is get someone that can weld the two different types of metal(axle housing to the spring perch).. the rear is easy..

You will need several grinding wheels a sawzall and a torch if you have one.

Probably nothing yet. <IMG SRC="smilies/biggrin.gif" border="0">


All you need to do for the rear it put new Spring perches on bet the pinion angle correct and stick the perches on.

No need to move the spring hangers or anything else.

does anyone think it would be better to grind a flat spot on the casting and drill a hole for a spring pin, or would you rather grind a radius so you can weld on a perch? id like to stay away from weldong dissimilar metals if possible.......also, has anyone ground grooves for the ubolts?

Thats a lot of grinding to do to make a flat section on top of that housing.

I did grind the grooves for the ubolts damn what a pain that was.

i did a spring over.. under a yj frame.. no need to outboard.. or cut down the axles..
pictures and what not are on my website below..
i also ground a radius for the perch.. and grooves for the u bolts.. its a pain.. also keep in mind when you do this.. and you weld a spring perch on top of the diff housing.. the hieght above the axle tube of the mounting surface of the spring perch.. i had to weld on like 3/8" more to the drivers side perch to get it equal hieghts.. no bigging unless you forget to do this.. then you get the leans..

Brian, you need to take a good look at mine some time. I don't think there is really enough meat there to just have the casting as a pad. Grind it enough to fit the perch, then also cut some off the bottom of the perch so it comes out the same height as the other pad. I cut mine down far enough that I had to drill a hole in the casting to clear the spring center bolt. Some grooving is neccessary to get the u bolts to fit right, but that can be done with an angle grinder.

Use the stock cast SUA perch on the driver's side for your new SOA perch on the housing. Then you're welding cast to cast. Mucho ginding though. The u-bolts are easy, just takes some time like others have mentioned.
