Steering wander with 3" lift

[landtank]

No two same model cars behave exactly same, not even the day they roll off the line. Add 20 years, multiple owners, and all parts at various stages of degradation from newly replaced to never replaced in 200k miles and what you have is a car that behaves according to these conditions and unlike most cars that look like it. This is why I spent a lot of money replacing “stuff” early on to eliminate as many idiosyncrasies as possible.

And, you took the term “personalities” literally.

the vast majority of cars rolling off the assembly line drive the same and are built within a consistent design tolerance. When designing mods, even for a 20yo vehicle, you do so to that standard. Nobody is going to design a caster plate to work for a vehicle with worn out bushings.

So if you install a mod that has proven to work but doesn't for you then it's a good possibility your truck is the problem.

And I've been servicing equipment since 1981 and fully understand the term personalities when talking about multiple machines of that same design.

True, but my point was , that not all aspects of a new vehicle are EXACTLY identical and, unless completely restored in one shot, most of us drive around in an old 80 series that has new this and old that until everything is brought back to within factory tolerances. I don't think every 80 rolled out of the factory with the same exact castor numbers for example. Heck, mine has castor angle difference of about .5 degrees from one side to the other.

I have a stock 80 with the ome 2.5” suspension lift on 35s. I’m guessing I’m on the high side perhaps exceeding 2.5” lift given zero added weight.

I have the ome caster correction bushings installed but the alignment shop let me know today that I’m at zero caster or even negative caster currently. It doesn’t drive like crap but would like to get to stock positive 3-4.

Are these slee control arms a viable option to welding in caster plates for my setup? Only concern is the 6” lift application. Wondering if I’ll get too much positive caster.

Many thanks.

If you have questions about Slee products, call them up. They are very knowledgeable about the 80 series and can help you dial in your caster issue.

I think that you will need to go back to stock bushings if going the caster plate route...

Good luck!

If you installed a 2.5 lift and have negative caster would adding weight like bumpers and sliders change the caster?

They’re not easy to reach over phone. Plus I want to hear from you guys. Thanks.

No idea and don’t want to. Thanks.

Thanks for your useless answer. So let me ask this again on a different way. Forgive me ahead of time CYKBC. Does the weight to spring ratio have an effect on the vehicles caster angle?

Chill dude. Wasn’t trying to be mean. Thought you were asking me.

yes, it's all about the final ride height of the truck, not what got you there.
