hey thanks for the information. I think my dad has an air wrench that i could use. So ill just have to take it back home to work on. He also has a jack and probably some blocks to use instead of jack stands.
Don't do as block! It will increase axle wrap and break down the spring more. Shacle would be easiest, but you wil need a good jack and jack stands
Best way is to add a leaf. But not one of the trailmaster ones thats a curved overload spring. Find a real leafe that fits between 2 of the longer springs. You should have a spring place in your town. or find one out of a pack in the junkyard. maybe 2 wrangelr springs. the're thin and flexy. you will also need new center pins. The stock one wil not be long enough, and they will most likely break.
That brings me to my next sugestion. Watch yourself ass you disasemble the pack. Put a clamp on both sies of the center pin so they don't got flying when you take the pin out. You could hurt yourself if the pin breaks.
You may want to get new U bolts too. Maybe even do a U bolt flip while your at it. This will require relocation of the shocks.
alot of the sag is an illusion. If you look at the body seam the tops of the tires are close to the same. However the front wheel well is cut out more that the rear from the factory. So it makes people think it is sagging, and amplifies an acualy sag.
Every stock 4Runner I have seen has butt sag, and it is not an illusion. They generally are riding on the overloads by now. Blocks AND shackles are ghetto when the leafs are sagged.
If it were mine, a pair of Marlin springs would make it onto the rear quicker than ... well ... something really quick. This requires the addition of new spring hangers about 5" forward of the stockers - DON'T panic, it is exceptionally easy to do for the price of a pizza and the formation of a friendship with someone with a welder. What you will end up with is noticeably improved articulation, a nicer ride, and best of all, no sag.
Crank the tbars, or better yet, contact 4Crawler for some ball joint spacers and you should be able to fit 33s with no problem.
