Topic: Missing tack bar in front?

[Steve-0]

My bad. There ARE shackles in the rear, just couldnt see them as they are tucked away behind the bumper. So both front and rear have shackles in the back of the springs. looks like possibly some home-made shackles for the front and the rear has stock-looking shackles (kind of bone shaped).

Here are the fronts...

[jfrabat]

OK, so you do have the front shackle...

[jfrabat]

Oh, and one more thing; a sttering stabilizer will probably help reduce the effects a little...  Just a thought, as they ussually are about $35.  Keep in mind, though, that this is a band-aid fix and leaves the main issues unresolved!

I am not sure if there is one or not (seems there is, but I dont know the condition, as it looks like the stock one), but just in case...

[Jesse-James]

I would definitely start with a drop pitman arm.

he's got one on (looks stock so probably not in good shape) - but yeah, x2 a new one would help.

also Jeffy mentioned the drop pitman arm, that helps too.

or a tie rod flip...

Well, if he had no shackles, he wouldn't have bumpsteer. 

*** Ah, see first pict shows a shackle

[jfrabat]

Well, he would have LOTS of bump, though!

I'm going to blame the bump steer on the non lift Pitman arm on the steering box.

If your in the PNW near Portland Oregon go to Leonard's Off-road and Fab in Hillsboro.

Looks like you have a lift+ a shackle reversal, the front looks like a kit. There used
to be a outfit in Portland that built one that looked like that, can't remember their name.

My track bars/panard rods have been gone for 10 years, I still run the swaybar, my lift is just
soft enough it has bad manners on road under hard braking without it...
(RC springs and Black Diamond Shocks.)

Well, it is for sure because of the steering geometry.  The suspension is just making it more apparent.

[dwtaylorpdx]

I put my lift on back in the day, didn't have the tools to get
the pitman arm off so I installed the lift and drove to the
shop to get the pitman installed. Definately had wicked bump steer.

Meant to note that in my last post and got distracted...

Thanks. I guess I dont get the steering geometry, why lowering one end of the drag link would reduce or eliminate bump steer.

[sharpxmen]

Thanks. I guess I dont get the steering geometry, why lowering one end of the drag link would reduce or eliminate bump steer.

it's at an angle, when the front of the frame goes down in braking the distance between the steering knuckle and the pitman arm remains the same   (distance between 2 vertical lines thru the center of the holes in the knucke and pitman arm) but the projection of the drag link to the horizontal is longer b/c the angle of the drag link to the horizontal decreases (the pitman arm moves towards the ground along with the frame) - that pushes the 2 away from each-other - the smaller the angle at which the drag link rests the lesser the effect. Let me know if i explained it ok, if not i'll give it another shot in different words.
