Finnally I lifted the front of my F250. I found a set of F350 springs and slapped them in. It finnally sits level. It rides better and no more of that nasty toe in look. Just wanted to show my excitement. --Thanks guys

 

what year did you do this to??? I have an add-of-leaf on a 94 that is shot

 

I did it to my 87 F250. Stadard cab long bed 4x4 with a 6.9L

 

i need to level my 2wd f250 i wonder if i used f350 dually springs if it would work

 

87 4x4, is that a ttb leaf??? I bet the 2wd is a coil. I guess 350 stuff, leaf or coil, should replace the 250 leaf or coil. Just make sure I get the right one!!

 

Usually the 2wd is coil springs either way 350 will replace 250 given 2wd or 4wd. Make sure your measurements from center bushing to center bushing are the same and your golden. I would recommend buying a polyurethane bushing set to replace your old ones with. Mine were destroyed but luckily the "new old ones" were alot better. Now that ive decided to get all new hardware, i wish i would have thought of it sooner. Could have saved me time and trouble. And my 87 is a ttb but will soon be solid.

 

On the TTB front axle it don't take much to raise the front to far for the front end alignment to be off more than you can correct with the adjustments.

I played with my air bags while it was on an alignment rack one time.
20 pounds of air in the bags raised the front about 1.5"
That was more than the adjustments could handle.
I don't remember for sure, but I think camber was the one that could not be corrected.

 

Thanks Dave. The tires are leaning in at the top now with an old add-a-leaf. I need just a little help. I used to put twist locks in the coils. I don't want to go too far. What brand air bag did you use?? One made for our trucks?? Thanks

 

I tried to get my truck aligned a couple of weeks ago and they couldn't get camber within spec. The previous owner of my truck added a leaf to the front suspension for a lift. I was wondering if that may have been the culprit. Looks like I gotta 'nuther job to do tomorrow...

Even though it looks funny, after I experimented with the Firestone Ride Rite air bags on my front axle I determined the IFS (TTB) front axle has tires at best in the vertical position.
For alignment to be right on the bottom needs to be just a bit wider than the top. / \

I know it looks funny, but tires cost to much to tear up because of looks.

When you look at the front tires, drive straight forward on a level surface and come to a stop.
Then look at the tires.
If you back up and stop, when you look at the tires the angle is always worse looking, partly because of the toe in.

Also the springs are meant to have a negative arch.

Something else to look at if your tire lean is excessive is the front spring shackle.
I only had about 3/4" clearance between the bump block and the bump stop.
I also had a clunk in the front I could never find when I hit rough road.
So I thought the front springs were shot, I ordered new ones with two extra leaves since I was also upgadeing to a Dana 60 soon.
It was a nice day here one weekend, so I decided to change the front springs before I did the axle.
When I dropped the springs, as the front shackle came down out of the frame I noticed the upper bushing was gone and the bolt was wearing into the shackle about 1/2 bolt width.
Since I was just messing around, I though I would see how the new springs sat if I removed the two extra leaves from one of them.
So I took the extra leaves out, and installed the new shackles and hardware and just let the truck down on the new spring.
Same exact negative arch, but now I had about 1.5" between the bump stop and bump block.
The old springs were fine, the mounting hardware was shot.

So I jacked the truck back up and installed one of the two extra leaves and removed a leaf from the other side spring and put it all back together.
When I let it down this time, the springs were straight and I had about 2.5" between the stop and the block.
Also the top of the tires was farther apart than the bottom. \ /
Truck did not drive very well until I installed the 60.
Now I have both extra leaves installed, the 60 is in.
Air bags are not needed even with the plow installed.
I have lots of room between the block and stop, the springs have a slight positive arch.
They are so stiff I will never be able to bottom them out against the bump stop no matter what I hang on the front of the truck.

Moral of long story, if you think you need new front springs, start with new front spring shackles.
Even if you need new springs, since the shackles are new it will be much easier to swap springs.

 

Took most of the day but I got the leveler kit off my truck and returned it to stock; looks just like the drawings in the shop manual. Can't wait to get it to an alignment shop so I don't tear up the front tires like the previous owner did.

From Dave,"Moral of long story, if you think you need new front springs, start with new front spring shackles.

Thanks for the info on the hangers...I have the noise when I hit a bad bump. I'll check them first!!!
