alignment specs

Hey guys, i got in a accident a last week that involved me hitting a curb at speed which threw off my alignment. I have a appointment for an alignment tomorrow and i have to provide the specs.

I i found the general consensus for the camber is around 1.5-0* and the castor to be around 6* positive.

However I cant find a definite answer for what the toe in should be? what do you recommend for 31's and stock suspension

thanks

 

I'm running 1/8" toed in on mud style tires. I think 1/32" to 1/16" toed in would be a good place to start.

 

The last time I did this, I adjusted the drag link to get the wheel strait. Then checked the toe and found it was still good. I'm sure you could easily check this without going to a shop.

 

i would to that except im at school 300 miles from home and i dont have to tools to do that with me. Plus i want to get it all checked out before i drive it 6hrs home next week. Is at no cost to me, im just going to make a claim on the other guys insurance( he was at fault)

 

I agree with the above to start at 1/32" - 1/16", and go from there if needed. Watch the wear on your tires, and you can tell if it needs adjusting. I'd have the shop check your rims while there too... it don't hurt and may save you down the road.R)

 

Looked up the specs.
King pin inclination pre '74 7 1/2* '74-'80 8 1/2*
Toe in 3/64"-3/32"
Camber +1 degree 30minutes
Caster 3*
Wheel pivot ratio (also called toe out on turns) 20* inner and outer

Hope this wasn't way too late.....

Any alignment shop should know what these mean. If not, go somewhere else....

What is king pin inclination? (don't bring it to me )

 

King Pin Inclination, Steering Axis Inclination, and Ball Joint Inclination are all the same. Basically if looking from the front of the vehicle you draw a line vertically through the upper king pin (or ball joint) down through the lower king pin (or ball joint) you get the King pin inclination. The lower pivot point is normally farther out from the vehicle than the top pivot point. The idea is to cause the spindle to travel in an arc when turning to raise the vehicle on that side. The weight of the vehicle pushing down on the spindle tries to keep the wheels straight ahead when driving. This increases stability, directional control, and steering wheel returnability to the straight ahead position. Add this with camber and you get the included angle which is used for diagnosis of damaged suspension and steering components.

Don't confuse this with caster which is the angle that causes the wheel to follow the knuckle for stability. This angle is viewed from the side when you draw a line through the same two points as above. Hope this is clearer than mud?

Very clear now. Guess I have just never heard it called that. I have heard the Steering Axis Inclination. Thanks for the enlightenment.
