This is something I noticed when I bought this used 2 years ago, doesn't happen over light to medium bumps, but at hwy speeds over a good bump, the steering wheel will shake back and forth a couple times then quickly settle.
What I have done since purchase is new Defender LTX, new OE front diff mount brackets, new hub and bearings, new brake calipers, rotors, pads, and new OE strut cartridges. I had an alignment done with the new tires and also a week ago.
I do have the OE 22" wheels if that matters.
The upper and lower ball joints are good.
There is no looseness of the outer tie rods, they are tight.
I don't notice any wobble or play in the steering rods, and the steering is tight when driving, no dead spot on center.
My only thought is the mass of the wheel/tires just overcomes the steering for a moment. So should this never happen or normal for the GMT900?
Maybe the rack is slightly worn and only shows it's face with a stiff jolt/tremor of a bump at hwy speeds. This shake is very quick, just a couple slight back and forth movements of the wheel and it settles, nothing like a death wobble or a constant spring oscillation.
The steering rack mounts are tight also.
I will try to get a video in the coming days.
