front end jumps around..squirrelly bronco!

Man, my truck has gotten bad squirrelly lately. The front end will catch a little line in the road and follow it and I have to constantly correct the steering. I jacked up either sided and balljoints and bearings seemed fine. I have 6" lift and 33x12.5's, and i didn't put in new axle pivot bushings when I lifted so that could be it... Other ideas?

It's a Jeep thing? My Bronco thing will run over your little Jeep thing.

Have you had the alignment checked lately? Lack of positive caster can cause the front end to track erratically. Other than that you may want to check your steering system to see if anything is loose (including gear preload over center).

I tightened up the steering box a couple turns awhile back, but didn't really understand the explanation in the haynes manual of how to properly set the preload. What exactly do I have to do?

If the steering wheel doesn't return to center by itself when you let it go after a turn, you have the backlash of the steering box gears too tight. Loosen nut 1/4 turn and test drive until it feels right.

As far as loose steering, do you have a heavy duty steering stabilizer. If you don't, get one. They are worth their weight in gold.

Try having someone turn the wheel back and forth with the truck off and look at the steering linkage - I'd bet you've got a least one loose end - often a segment will get worn in front of the steering stabilizer - so the stabilizer can't do anything about it. I think large tires are prone to this condition, or at least they emphasize any problem you may have had - I put some used 36" goodyear military tires on one of my '78s - the truck drove fine before - but now is a really big handfull, and certain bumps at certain speeds can set it oscillating which is just no fun if you've ever had it happen. But I've got $600 in the truck so far so I figgure I'll fix it when I get around to it.
