Dana 60 Real World Caster Spec's?

[5280k5]

In my eternal quest to solve my death wobble issues I'm trying to get the caster as close to spec (4 degrees positive 74-76 k5). Just wondering what everyone else has their's set to or how close to spec

And yes, kingpins are rebuilt, bearings tight, steering new and tires at 15 psi.

I dont think you should set it to K5 specs because they were ball joint axles.
I would set the allignment to the specs of say a 1978 K30 SRW.
But then you probably already no that but hay!!!!

all specs I've always seen were actually 7* on K5s.

We were debating this at work but our front end guy kept saying to set it up to the chassis the axle is under not the other way around. The spec's for the newer stuff, 77-up goes up to 8 degrees positive but 74-76 shows 4
Right now as it sits I'm at 7 degrees positive, but I'm planning on shoving the axle forward 1.5" which will only increase my caster more.


Easter lunch is calling gotta go, I'll check back later, thanks guys for your help!

The chassis i dont think makes that big of a diff.
The front end guy at my shop says the opp.
I think it would make more sense to set it for a k30.
The axle is the one that has all of the moving parts and is adjustable.
The axle mounts to the frame the same way on both trucks so i dont see why the chassis would matter. I think the specs on a kingpin axle and a ball joint axle will be a lot different...

Just my 2cents
