87 Sami with the following mods related to driving/steering:

3" Calmini lift springs
6" shackles (3" of lift rear; 2" front)
1" rear driveshaft spacer
RRO shocks
Drop pitman + Stage 1 and 2 high steer (pretty close to level)
All new wheel seals/bearings, rebuilt whole front axle/knuckles
31" TSL.  Fronts are like new

This truck will knock your teeth out if you have any that are loose.  The other issue is pretty hard bump steer and a lot of higher speed swaying.  If i touch the center line with a tire, it really pulls it hard.  Now this is the only sami I have drivin so I dont have a comparison.  Upgrading the shock up front should fix bump steer.  Anyone else with a similliar setup?

One thing I did notice is the "U" shape stablizer bar up front is missing via previous owner.  This could be a major factor I suppose.  The other is I realize TSL's are not the most comfy street tires. 

Anything else I can check besides alignment? 
How about the knock your teeth out ride over tiny bumps? TIA

I had the same symptoms in a Heep I had. The previous owner put shackles that were way to long on it messing up the geometry.

Thx. I could easily lower them back to "close to stock" and see if there is a noticable diff.  I have read mixed reviews on Calmini 3". Some say its too rough, others liked it.  I just wonder how this compares to SPOA with stock springs.  We dont do any hard off-roading... mostly woods riding.

I realize its not IFS ride quality but I thought my brothers older CJ was bad years ago!!!

Definately check back on the thread. There are a lot of people here that have built mank Sami's and will have some good insight on the kit.

Quick thing to check is your tire pressure.  It is probably in the 30 range, should be in the mid-to-low 20's.

def.  All the simple checks in order. tire tread/pressure, new bushings on leafs... already replaced the bearings and tie-rods (upgraded actually).

Thx.

I did shorten front shackles back to smallest/factory. Waiting a test drive on the shaking front end still.  Any ideas on rough ride?

Okay so a test run didnt change anything.

The truck just has like slop in the steering. Like constanly micro-steering left to right.  This left/right action is very responsive is the main issue. Its like I am drunk driving and swerving.  Hard to explain it exactly.

There is 'some' play in the steering box and the steering U-Joint.  This would fix the play but its still gonna leave it VERY sensitive to where i correct to stay in my lane and it literally pulls me that way.

Go with Zukipilots suggestion, get those shackles down to a decent size. 

And put bolts that fit real snug in the bushings, All of them! I run mine at under twenty pounds on hwy and about four off hwy. get a good steering stabilizer that hooks from your tie rod to the front diff tube along with the stock steering stabilizer also.

Ditch the swampers. Try a quality radial

Get under the front of your rig and have someone steer the vehicle left and right. Look for any worn parts.

Thx for all the ideas. Shackles are at stock with no change.

All parts up front are new bushings, new grade 8 harware, and snug.

I will replace drag link shock next and steering shaft u joint near firewall. Rag joint looks okay.
I going to try finding some diff front tires to test drive before buying new.

More research lead me to tightening up the screw on the steering box.  This fixed about 85% of the scary steering.

The other 15% of play is coming from the steering shaft right where it leaves the firewall (upside of the u-joint).  I assume there is a bearing or bushing of some sort that is replaceable?

Lowered shackles seemed to help the bumpy ride 'some'.

not sure that you could buy that bushing ! you might have to buy another shaft and try to rob it, or smash the upper tube a little with the bottom one pulled out and get it tight, I could not imagine anyone hearing a noise from it. Who needs plastic?

My 2 Bits;

Also check your front wheel bearings, You will need a Torque Wrench,
  the correct way to "set" them  is in the FSM.
You can use a 2" socket if you don't have the metric equivilant.

Second, as a thought, make sure your back suspension is "All Tight" too!!
A broken center bolt, loose spring bolts, cracked spring in the rear can make it feel like a steering problem.
