Ok,

Well my truck has been dropped with 2" Struts in the past.
Now with 2" Spindles and 2" Springs.

PS=Power Steering

I never had problems with both setups until about almost 2 weeks ago, I noticed when coming to a halt, my PS firms up making it a bit harder to steer the truck in my desired direction. A few times it has jerked to the side(both left & right). It's fine at high speeds, only during slow speeds that i notice so far. It's at the dealer now, but it seems like they are blaming the drop..."the rack and pinion is at an odd angle" Could something be causing it to bind up???

Thanks Fellas !

Has anyone else had any issues on their 2007+ GMT900???

That happened to me as well. Lets say if I went to reverse into a parking spot, It would suddenly become super stiff to turn the steering wheel to back in. Only happens to me once in a month or so? Never any problems at road speeds.

This was before my drop mind you, has happened once or twice since too.

Sounds almost like it could be a pump on its way out or your fluid is bad (contamination or air). Is it making any noise? I don't have much experience with r&p steering, but 4" of drop doesn't seem extreme enough to cause problems.

severe forward angles will cause the steering to bind.. :read:

they have a TSB on the rack leaking, maybe it was just low on fluid

I thought the same thing when I read the title.

FWIW when I park at school the parking lot is a hard blacktop that's really rough and I have noticed it's harder to turn the wheel there but anywhere else it's fine.

I bet it's that cheap powdercoating job on those spindles. Some of it got built up in your TREs. Or the dust shield needs to be trimmed. Or the balljoint is TOO seated so it cant turn properly.

:crazy:

FUCK ME! I hope that's not what's wrong with mine.

Did your steering wheel go un-level?

I think I'd rather pay to replace everything than put it back to stock height and then lower it agian.
