Sagging Rear, Endless Problem?
Well, I am going to do something about it, finally. Ordered JC Whitney replacement leafs for the back and some nitro 9000 shocks. Also considering the add-a-leaf with longer shackles. This should net me a couples inches of lift in the back to help with hauling of the gear; tools, jacks, coolers, tent, etc...
I know new u-bolts are needed. Any tips on swapping leafs for a first timer besides lots of PB Blaster?
Any experiences with these springs and shocks? Ride quality, ease of install on 1st Gen 4 Runner?

work on flat ground if possible.
block and chock the front wheels regardless of slope.
have a small bottle jack available.
do one side at a time if you are working alone
jack the entire rear end up if you can.
spray penetrating lube on every fastener and let set at least 12 hours.
I can't say with certainty anything about your springs, but I installed a pair of 4" lift procomp springs on my 88 in about 5 hours by myself, working on a sloped driveway.

Other saggy Runner guys have went this route......

Here's the link to get a super deal on 2.5" X 12" coils....your choice of 150 or 125 pounds per inch.....29.99 each plus shipping. http://cgi.ebay.com/ebaymotors/NEW-R...mZ290014123883
Make up an upper mount and you're all set. 2.5" of lift....better ride......more payload ability. And it will likely never sag again....in your Runners life.

I would keep hitting these bolts 2x a day with pb blaster for a few days. Its easy and will help you out once the time comes to get down to it.
Do you have a grinder on hand? I had to cut off my old u-bolts when I put my aal in, they were seized in place.
also, once your done, if the suspension is higher then stock (more then an inch) take the time and make a LSPV lift bracket.

Thanks to all, zuk, dirtoyboy and jay. I never thought about the load sensing proportioning valve (LSPV). I will keeo it in mind.
zuk, very inventive idea with those coils. Does it effect off-roading at all?
Does adding an AAL require anything special, like different, longer pins for the leafs?

I thought of OME, but decided to go with JCWhitney, possible addition of AAL's and new shocks, their nitro 9000's. I am hoping Rancho makes them shocks.

Just read the customer feedback comments...it says it all.
Don't forget to read this long long threads also....
http://www.4x4wire.com/forums/showfl...5&o=31&fpart=1
There's no reason for me to supply kits anymore....anybody can order up the coils themselves and fab a simple upper and the somewhat optional lower mount. If someone can't fab them then I might be able to fix them up with that part.
Things may vary slightly from Runner to Runner but here's some lift info...
The 2.5" X 12" 125 pounds/inch rated coil gives 2.3" lift
The 2.5" X 12" 150 pounds/inch rated coil gives 2.5" lift
The 2.5" X 14" 100 pounds/inch rated coil gives 3.0" lift
The 2.5" X 14" 150 pounds/inch rated coil gives 3.5" lift

zuk, yes that was an incredibly loooooooooooooooong thread. It is an entirely do-able idea. I am going to put my new springs in anyway to get experience doing it and will put some coils in for lift & to prevent future sag. Do you still make and sell brackets for these? I would be interested in buying some if you do. That way, as said in the thread, I can source my own coils.
I would try to make the brackets myself, but I do not weld yet and do not have room (apartment living). you can PM me or e mail me;
vambo213@yahoo.com
Great thread, thanks.
My next project to save for is going to be gears - 5.29's and a V6 locker.

Thanks alot to all who answered and offered advice.
Thanks also to ZUK... Great resource for info and helpful in many ways. I will be installing Zuk's coil spring mod as well.
Waiting for leafs to arrive with shocks.
Waiting for Zuk's brackets to arrive.
Ordered a u-bolt flip kit from WabFab.

Here I go, tearing apart the 21 yr. old rear suspension. I have a flip kit from WabFab but didn't use it, just re-installed the old plates because I have no new shock mounts yet. I bought the leaf springs from JC Whitney and got the nitro 9000 shocks also. Shackles are from Kragen. Bought bushings from Summit Racing.
Zuk's brackets came today while I was tearing everything apart. I will install his brackets when I do the flip kit and get the new shocks mounts put on.
Here is the old suspension, 2 3/8 inches between the top of tire and bottom of wheel well.
Had to remove the spare first.
Only have this for factory tool kit.
Jacked it up.
Removed shocks.
Removing shackles and bolts.
Tension on the leafs boogered these.
Out with the old.
OOps!!!! Manipulating the leafs around the brackets and e brake cable, I caught it and the axle fell off the jack.
Finished it. Working by myself, this was an all day job.
Incredible !!!! I gained a little over 3.5 inches above the tire.
I will deal with the D Shaft tomorrow. Then I will test drive it and re-torque everything again. Incredible results.
JC Whitney Leaf Springs $125.00 each + shipping
Shocks $36.00 each, shipped with leaf springs
Summit Bushings $36.00 w/ extra grease
Kragen Shackles $21.00 w/ tax

Anybody ever swap leaf springs and shocks and not lift their vehicle, trying to get a better ride with closer to stock height? After I put the 1.25 inch B.L. on and the 33 inch tires, I just don't know if I want to go any higher.
Although this is not done, I have Zuk coil spring cups, a flip kit and new shock mounts to install.
At least I can drive it again.
