    SAS Steering feels sloppy??

    I got the 88 rolling and carried it to the alignment shop. It has all of 14 miles on it post-SAS but it feels kinda sloppy. I got the toe in to about 1/8" and it runs true, no death wobble even without a steering stabilizer. i did notice that when i turn left, the right side of the truck dips down and vice versa, camber related I am certain. It goes lock to lock easily and runs straight down the road. the issue is that as the suspension flexes is seems to want to change steering angle, which would be "bump steer". When I crossed railroad tracks this morning it nearly changed lanes on me but it did not get all squirrelly on me and skate out of control. I was expecting it to do that so I was ready. Truck recovered very well. Will adding a stabilizer decrease the bump steer tendency? The tie rod and drag link are parallel and level at center so it's not a pitman angle issue.

    By loose or sloppy, I mean there is no real resistance to the steering wheel when turning. The truck feels lazy, not responsive to steering input. I know it obviously ain't no Corvette so some degree of latency is to be expected. Anyway, here it is all buttoned up, for now anyway..

      Steering box is tight, no play. trunions and bearings are all new. Rag joint is fine, checked it when I rotated the steering box. Box is torqued to the frame well. I'm not 100 percent certain on the castor angle but i do know that it is defiantly positive. The alignment shop is supposed to check that and give me the readout.

        Les swab did an "alignment" on my 83 that consisted of setting the toe and taking measurements and handing me a bill.

          I did a rough alignment on it and it was a combined 3 degrees toe-in. the shop is checking the caster angle for me so i will know what it is and how it may need to be adjusted.

            Sounds like someone is used to ifs with sway bar and not solid axle with no sway bar....

              Exactly. When my springs broke in the entire truck felt like a bowl of spaghetti.

                I got pulled over in my 85 with 40" boggers for swerving. Cop asked if I had been drinking. I said nope, it's an old piece of shit on 40s. It goes where it wants

                  How the hell do you perform a SAS, and not know how to put a degree finder on the trunion cap/steering arm for castor? And no, adding a bullshit shock to your steering doesnt 'fix' anything.

                  I cant tell from the pic, but did you use a kit? Home brew? If so what pieces and parts.

                    SAS with crossover is not going to be Rack and Pinion. Add a ram assist, it firms it up.

                      No kit, just a guy with a big imagination.

                      The alignment helped tremendously. I can tell the difference from the IFS and I know it won't be anywhere near the same feel. I did not expect it to steer like a jon boat though.. after the alignment it feels like other trucks I have driven. The steering wheel has a bit of weight to it but not too much. The bump steer is all but gone. It is much more responsive and still very stable at highway speed. According to my wife's speedometer we were running 65 most of the way home for about 20 miles, hit 70 a couple times.

                      In other news, the muffler fell off on the way home. I heard it and knew what happened, wife (who was driving behind me) and had me in complete hysterics. Conversation went like so:

                      Wife: Did you just hit something in the road?
                      me: no, I think that was my muffler.
                      Wife: how the f... Do you lose a muffler??

                      ​​​​​Been patching the exhaust but when there is more rust than pipe it's hard to make anything stay.. seems now would be the perfect time for a header since the entire exhaust needs to be replaced from the manifold back.

                        If you had it toe in 1/8" I dont know what an alignment shop could have adjusted to fix anything. Unless you were off on your measurements.

                          I'm pretty sure I was off on my measurements. Or, when I tightened everything down it moved. Possibly a combination of both.

                            You can add a trackbar/panhard bar for improved steering response. Factory leafspring jeep YJs have trackbars, also 90s fords with a dana 60.

                              Thats how my IFS with no swaybar feels. You never drive a piece of shit before?

                              How did you do your "alignment"? What did you measure to and from?
