Steering issues and shocks.....Help!

[Rogue 64]

I have a '99 in my shop that has a serious bump steer.
Alignment shop and Dealer can not fix it.
It has the Rack and Pinion steering.
During this diagnosis the shocks were changed, it now has 80k.
I found the split upper shock biscuits sitting on the frame rail.
We looked at all replacement shocks we could find and all had the usual upper and lower biscuits.
I found a replacement upper mount bushing.
What's the deal, the replacement shocks obviosly will not work on this truck. How many others have these shocks on them?

I know these are 2 different problems but my knowlege is on much older vehicles

I understand that GM did a recall on the rack equiped 1500's but according to the dealer this truck's vin is not included.
