I'm Looking at Truck

[Port&PolishMan]

Doctor - DS Raven - I Assume - well that puts Me under the Truck in the morning.
As I can see - .005 Off on a 8ft Sheet - which everyone else says looks good to go ..

Tire wear of tire is also saying something - ?

Checking ?

OK - Just Crawled from under the 1 Ton Rock `\ : - )

Pictures Soon :

Picture 1 - Looks like the Delivery ( Travel ) didn't Go to Smooth
[IMG][/IMG]

Chains was way to Tight or He had to Hit the Brakes Freaking Hard & Fast !

Resulting In :

We took it for a Short Test Drive : Didn't Notice as just on side Ruff road and Busy looking at all the other Area's ..

Wonder How Time & Cost this is Going to Be :

looks like the spring pack has shifted. check to make sure there are no broken leaves in the packs, then block the wheels (fronts) for safety and loosen the spring u bolts slightly, enough to allow the spring pack to be hammered back where they are all lined up, then retorque the U bolts. you could, while the U bolts are loose, check to ensure the spring pack centre bolt/pin is sitting in the spring pad correctly (on the diff) that would take care of the possible dog tracking issue. the u bolts would need to be loosened off a bunch to allow some gap between the spring pack and the diff pad so ensure you block the front wheels. you will also need to jack the truck up or the diff up to get some gap there. some will say the U bolts should be replaced, which is probably true, but there are lots of retorqued spring U bolts out there. I guess you would be the judge of that since we don't have eyes on the bolts so don't know how old or rusty they are.

[dwcsr]

Almost always when the spring shifts like that the u-bolt is loose and the center pin is broken and maybe a leaf is broken. It should come apart and repaired. Get a center pin from a spring shop do not use a bolt. Center pins are a special grade and made to shear at a particular stress. Don't try to clamp the spring stack together with the new center bolt it will damage the new bolt, clamp it then bolt it.

[dsraven]

yup, what dwcsr said. if you try to clamp the spring pack down with the centre bolt it will just strip the bolt threads.
is the housing leaking as well? pic?

Slight Seeping .

Long Day . Insurance , Paper work , DMV - Sales Tax , Go to Bank etc.

OK First Up - I'[m so Glad I caught this Early before it Cut a Good Tire ..
Then Thanked My Granddad for Giving His Favorite Jacks , as Your able to work them
in Close Quarters - these - Crank Easy are Strong .

Tthe Information Given or I may have Never tried to do this . .

Just Getting Photo's Up -

Jacking :
[IMG][/IMG]

[dsraven]

nice jacks. they look like building movers would use.
can't see by the last pic but it looks like the spring centre bolt is gone. by the rust in the area I would say the U bolts were loose for a bit. rust running off like that, or powdered rust coloured dust if it is dry out, are indicators that something is moving or needs lube. since the area doesn't really have anything that would normally "move" it would indicate things were a bit loose. guess that's why the spring split out the side into the tire. lucky you found it.
check the spring centre bolt and the pad it fits into to make sure all is good.

[dsraven]

man, that thing is clean under there. nice. the 04 envoy I am using was a dirt road truck. took a long time with the pressure washer to get all the rocks and stuff out of the boxed frame and other areas.

Luckily the Pin was still in Shape , But it seems the Axle are still Out , even after Aligning :

[IMG][/IMG]

Third Jacking the Axle to Catch the Components back together .

Cleaned and Painted _ Reassembled still Dogged by .400 or so ..

[Port&PolishMan]

After a lot of Measuring and Checking everywhere - the Only Thing I'm able to come up with
The Restorer - Owner or Accident - caused all the Springs to be Out at 1 Time .
( Somehow they got Switched ) Left on Right and the Right on Left . .
the Center Short Divider pc. was in Backwards which may have lead to the This
as the Center holes did NOT - Align right . .

It is also Possible 1 is in Backwards - I can't Tell how those Dog Bones & Shackles -- come Apart ?
Passenger side has 1 Lose Shackle & Pin which is also Odd ..

[rapid49]

If the pin is centered in the spring perch and your measurement is off check the other side. It looks like the weld on your perch is cracked.

[dsraven]

I have found most of the bolts are more squred on the ends. maybe they are worn? able to slip around in the pad hole?

[dsraven]

I would have to agree on the cracked weld. maybe use some brake cleaner on the thing while it is apart and then warm the area up with a propane torch, not too hot just enough to get the lube moving. if you see oil in the "crack" then it is likely the culprit. easy to weld up while aprt as well.
take a plumb bob from the front spring u bolts or a common reference point up front, maybe the frame is better to eliminate wear in front end parts. do both sides and mark the floorunder the truck. then do the same on the rear and measure the difference between both sides and on an X pattern from front right to rear left and vice versa. that should let you know how far out you are. check all the front springs and shackles as well, since the whole truck was involved in whatever happened you wanna make sure the whole truck is good to go when done. also, don't wanna be referencing a front axle that is able to "walk" from worn out spring shackle bushings/pins.
I believe the shackle pins unscrew somehow, been awhile.

Thank You for Pointing that Out - it seemed Tight and Not Moving - may have
Happened before ..I measure from 6 different Places , with 6 Different
Degrees of Answers - In Others Words Nothing Corresponded as the Same amount - so I took that as being
Built in a Non- Jig Fashion ..
Telling Me - If these were in Fact ! - CORRECT - at 1 Time ( Even ) - then there must have been a Mix Up . ( Or ) 1 is in Backwards . Assuming Springs are Not Perfectly Centered !

There is a Trailing Effect with 1 side or ( Half of any 1 Spring ) - as being always slightly Longer ( Head Scratching )
(( Is that a Fact - I don't Know )) but seems to be Logical .

I Writing this Response to everyone's Input - as I'm certainly Not a Spring Designer and Simple Don't enough Experience to Know for Sure . .

I Helped rebuild one of these Similar Springs 40 yrs. ago at a Garage .
Something about the Shackles and which way they Pointed etc. To Far Back in Memory to Retrieve . .

OK Welder is on My List of Tools - I was Leaning in Heli-Arc Direction .
LOL

OK Start Over - the Picture with the Tire Rubbing is the Passenger side Rear
of Tire Rubbing - Axle went Backward .

I'm putting Up next 2 Photo's taken at the same Point and Referencing
Both Sides - 1 will have some fresh Paint on it that's Passenger side .

Look at these an Note Difference :

Driver's Side :
[IMG][/IMG]

Passenger Side :
[IMG][/IMG]

Third Option - Owner was Unaware . .

[Port&PolishMan]

The Painted Side - Passenger Side I know is Assembled Correctly and Chain Marks on
Axle - Con-inside with that Axle Movement .. = ( Poor Transport ) ..

The other side which is Measuring Long in Front - and Showing a Short Middle Pad in Back
Also seems to have been effected and Locator Pin - Slipped Forward @ 1 Time & has been there for awhile
( Tire Tread Wear Pattern ) - do to this Driver Side being Off -- Before .

Issue that happened . . during Transport - which has been Corrected .

Seems the Driver Side Must also Be Corrected ! - Even thou It looks like it has been this way for some
4K-5000 miles Miles .. - Previous Owner was Totally Unaware

dsraven those are antique railroad jacks, I have a couple and I have used them to jack up a house! haha

port&polish, your sentence structure and punctuation is baffling to me. It might be just me but I can hardly understand what you are saying.

that short piece of metal between the upper and lower spring pack is just a spacer and has no bearing on the weight carrying. I wouldn't worry too much if it is sticking out more or less towards the front of rear. what I would check though is that the hole for the spring bolt is not offset in that pad,it probably has a bump on the other side to align the upper set with the lower set. anyway, worth a look to ensure one of those is not in backwards so it offsets the wrong way.
check the main leaf, the one that attaches to the frame and the axle, to see if the measure from the front hanger is the same on both sides. maybe it was apart at some time and just put in backwards. been to long to remember if they are longer in the back side than the front.
maybe do a parallel check on the wheels to compare both sides to ensure your axle housing is not bent. if you have the wheels that have the big spokes on the hub and the wheels are actually just rings that sit on those spokes with wedges to hold them on, then you may have to remove the wheels to get a proper reading. check for a loose hub bearing at the same time.
check this site for info on your truck.maybe find something.

Thank You all so much _ I have a lot to Learn .
I read 142 pages on the Spec's for 4 Different Years just looking at Transmissions & Gearing _ Offered .

I have an Appointment with a Very Good Local Welder whom is Certified & does Hot Rods & Trucks .. He has already looked at and Agrees - Axle Off !

I'll also check the Bearings - as Both Load Pads are Broken so someone
has over Loaded and Hit Bumps !

Seeing there is going to be Welding on this Big Axle - I certainly don't want to Hurt the Bearings . .

My Old 49 Chevy Couple - had 6 Volt - it did run great - 3 on the Tree .
Chrome Bumpers - Light Green Dash and Doors on inside ..
Out side was all in Primer Brown - Steel was Thick all Good Original Glass .
I had the Seats redone - by local Seat Covering Place.
Had Spare in the back - this was 1976 in GA. when I found it .
Wish I had Kept it .
Guy I bought it from and Installed a New Motor - straight out of Sears Catalog.
He was USAF Mechanic .. and I did a little Body Work to Old Chevy .

I don't think We are able to do that any longer : Order an Engine from Sears - Drop Right In ..
