my neighbor is building this jeep...

i believe it's an 87.
complete 1 ton chevrolet axles under it.
stock YJ (i think) springs

i know he bought some parts off a guy in alabama to put this together.... the assembly went well, and everything measures out like it's supposed to. problem is... if you get up to about 25-30mph and hit the slightest bump, the wheels go nuts, shaking back and forth. similar to the "shakes" you can get on a motorcycle.

he called the guy he bought this kit from. the guy had him measure several things, all came out dead on. currently it has 4 degree shims on the front axle and the toe in is set at 1/4". EVERYTHING is tight... there is zero play in the steering wheel.

i'm limited in what i know about 4wd stuff, but from what i can tell, everything looks to be done correctly. anyway.... what needs to be done here?

here are some pics if they help...

With those tires, anything could be wrong. try different tires. and search this topic better. king pin rebuilds, bent tubes, sloppy tie rod ends. tons of stuff could be wrong. Your asking a question like why can't I hold my breath for 2 minutes while playing the piano... WE DON"T KNOW WHATS WRONG WITH YOUR RIG.

so we took off the part i circled in the picture below...

http://members.aol.com/sprayed95ta/kingpin.jpg

this is the kingpin... correct?

we added 2 washers to the spring in there on each side. it doesnt seem to have anymore death wobbl. however, it does seem to follow lines in the road more than before.

does this mean the kingpin needs to be rebuilt? or is it okay to leave it like it is?

i guess im off to do a search and find out exactly what that spring does... i hope this board isn't too advanced for suspension fundamentals.

I'm assuming your not circling the TRE (tie rod end), so what's behind that is the kingpin. it also seems that you learned something through the search button. congratulations. that said, the washer method is a band-aid to add preload to the spring. Alot of guys to it to control huge tires w/ new kingpins. since that fixed your wobble I'd definitely suggest replacing both kingpins w/ new units & get rid of the washers.

regarding it wandering, check the tires........:shaking:
