General Question
 

I bought a 2006 H2 SUT a few months ago which now has almost 89,000 mi. on the clock. This is my first Hummer, and I've never owned a truck so I don't know what the steering would have been like when it was brand new . I felt the steering was way too loose, and had my mechanic look it over. He replaced the following: Pitman Arm, Idler Arm, Gear Box, and Stabilizer Shock .
Steering has improved, but I would like to have it even tighter . DOES ANYONE HAVE A SUGGESTION WHAT ELSE CAN BE DONE TO MAKE THE STEERING EVEN TIGHTER ?
Thanks
