Ok, check all the lift and steering components, and I still get experience overly sensitive steering. I will be heading into the shop tomorrow morning for another alignment. The steering issue is similar to death wobble and I am looking at the possible causes: elongated bolt holes on the TB brackets, worn CA bushing front and rear. My hubs, ball-joints, and other hardware are good.
I did see in a few threads the recommendation of loosening the CA bolts, allowing the arms to adjust to the new height and then tighten them properly. I will attempt this as well.
My other area of concern would be the track of my front axle. I believe I have centered it the best I can. The measurements are close, but I found it hard to find reliable and consistent points to measure from for accuracy.
Any input you may have into these areas are welcome.
Here are some pics of the minor trimming I have done as well as spraying undercoating in the wheel well and along the downward facing portions of the fenders. I did this to protect from rubbing and rock chips. rust is our enemy here in the north east.
Define "alignment"? I would start with caster angle. Did the alignment shop give you a printout of the angles? On my ZJ I can make DW come and go with a 2 degree difference in the caster angle . . . and that's with completely unbalanced tires, sloppy track bar and bent tie rod.
I did not get a readout which I did think was funny, because they usually hand that out to everyone. Anyhow, I do not believe the DW to be from the change in caster. The reason being, the dw is not consistent. the jeep will be riding along straight and smooth at 65 or 70, then the shape of the road or something will cause a shift in the suspension or body position and the swaying will begin.
i removed the TB again today and looked at the bracket bolt holes. both bracket holes are round but seem to have excess wriggle room. I installed the bolts w/o the TB (not torqued down) and there is definite wiggle room for the bolt. I wonder if this is my cause or part of the cause. I may weld on some heavy washers to tighten up the holes.
The other area of concern is the rear A-arm ball joint. I need to check this for excess play. I know this can cause DW if bad.
Ok, after further investigation I have one bad upper control arm bushing for the front. This bushing is mounted in the axle. I will replace both the right and left at the same time.
I am also suspect of the bushing in my brand new JKS adjustable TB. They seem to have a lot of compression or give. This may be aiding the dw. Kinda weird that JKS would provide bushing that are not up to snuff. I may contact them about this. Considering the KOR upgrade kit.
I will also be welding some 1/8" metal plating to my TB mount with low clearance holes drilled to provided a sturdy hold.
I had my neighbor cycle my steering system left and right while feeling front suspension and steering linkage for clunking. I watched a video about this (I will post later). I feel clunking coming from my pitman arm area. I have brand new MOOG HD tie-rods installed, and I have checked for the correct tightness several times. I believe the clunking to be coming from my steering box. This may need adjusting. Any advise with that?
