How to get rid of a Saggy Rear???

[06 H3]

Front is easily adjustable and rancho specs are 26 to 26 1/2.

Stock height from factory is 22 1/2 front 24 1/2 rear so right now your under stock height in the rear left.

Yep...sounds like rancho springs

Hmmmmm, I wonder if this is why my driver side shock was pulled apart? My front is 27.25" but my CV angles are almost flat. They are angled at about 5 degrees. My rear is sitting at 27.5" with my Rancho springs.

I called up a shop and they said that they can build me custom Add a Leafs for about $150 for the pair, but if I am going to pull the pack apart to install wouldn't I be well enough just do go the whole way and do the SOA at the same time??

Has anyone done an Add-a-Leaf to a brand new Rancho pack?

I just called Rancho and they are are sending me a new set of springs, thought I would install some AAL's into them before I put them on the truck to tide me over until I can do an SOA this summer in my driveway...

Was hoping to hear if anyone has tried with good results?

Have a spring shop add an additional spring in between the main and second spring. This is not the normal location to add a spring but that is where we need it.

 

[jakesz28]

For a little more I had a shop make and install mine. New u bolts and I never even got dirty.

 

[RamRod]

This shop wants $600 to build and replace the leaf packs.... I will save some cash and do it myself.

I was thinking if I am going to add a leaf between the main and second spring, I might as well do a military wrap... any reason why I shouldn't?

(dropping the pack off today)

Military Wrap is a GREAT addition IMO. In the case that you break a main spring the military wrap will prevent total failure and let you drive home. I would love to add one to my stock pack.

 

[RamRod]

Can anyone tell me what to torque the U-bolts to? Installing new leafs tonight and then right after will be making a 200 mile trip south, I'll re torque the bolts and then tomorrow morning going wheeling with the new packs!

Thanks!

 

[RamRod]

Just checked the Rancho install instructions and they list 60lbs so I'll go with that I guess!

I will be re-arching the springs soon with a full length leaf added in. Shop wants $275 if I bring them in the springs. I've already picked up new bolts, bushings and u-bolts. Probably need to get some teflon spacers shortly too.

 

[RamRod]

The new springs with the add a leafs are 1000% better then old flat setup! Feels like a new truck!

Now just to swap out the Rancho shocks with something with more travel, brace up my steering with one of the fixes and the new diff bushing fix and I'll be set!

Just to keep things updated, so far this setup is going strong and now has settled in at a height of 4.25" over stock exactly where I was hoping they would be!

Began work today on getting the leaf springs re-arched with an additional full length leaf.
Took off the tires and supported the axle with heavy duty ratchet straps.

Removed the leaf spring bolts front and rear and pried the leaf springs from their mounts. Found that the bushings were a bit worn. Rear:

Front were better but still cracked/torn

GM does provide an indent in the gas tank for the front driver's side bolt, but yes, you need to remove the gas tank skid plate

Beat the tank back into shape with a sledgehammer and gave it a fresh coat of paint

Upper shackle bushings were also shot and replaced those. They needed to be pressed out with a ball joint press.

Also replaced the rear shocks since we had everything apart and the lower bushings were eaten up. They are a bit exposed in the tomp lo-pro mounts.

Tomorrow the springs go out for service.

Don't stop now. Keep going and get the rear axle ready for a SOA.

Just an update:

So after adding all the new front end parts and winch to the truck iI got my T bars cranked to bring me back to the right ride height... Got an alignment done... Now I can really see that my Rancho rear leaves have sagged even after doing an add a leaf! I am now measuring 25"... I imagine if I didn't do the AAL I would be back to stock height

I assume this happened after a two day trail run that had a good 20km's of higher speed wheelin' over a dried up river bed

So SOA is the way to go... I won't both getting these leafs fixed, I'll go straight to SOA in the fall

Dang, sorry to hear that. And these are new springs correct?

I'm guessing I lucked out. June made exactly one yea that I've had my Rancho lift on. I'm still sitting at 27.25 in the back and 26.75" in the front. But i also don't do hardcore off roading. Just muddin and mild off road excursions to my duck blind.

I'm going to check my rear end measurement and see where I'm at. Also I have all the SOA stuff ready to go just on the lazy side on doing it.

Looking at about 26"-27" all four corners.
