M35 highway bumps and a left right lurch

[readyman]

Last couple of outings I've noticed this when traveling at highway speed +50mph and going over bumps or dips. The truck first pulls to the left then to the right when landing back on the pavement.

Got kinda funny because the passengers would start to lean one way then the next to compensate after we hit any bump.

Is it inherent in the suspension? too light a load? tire pressure? alignment?
The rear axles are left/right loosey/goosey with the design of the rear dual axles/susp.

I didn't notice it with the NDT's, now with the XL's... well it's a handful. Maybe the XL's need to wear in? Or are the XL's just too bouncy?
Anybody notice this?

Don't believe very many of us would do this in the first place, I for one, can't tell you if it's normal or not....

check the steering gear bolts.

Not sure, but mine did it when I singled out the rear wheels and put on G286's. I lowered the tire pressure to 70psi and it solved the problem.

Long story short, check your tp and make sure all the tires are the SAME.
