How much gap should there be? I want to adjust the height up a little seems to be sagging a tiny bit. I remember it sitting higher in the rear.

 

How much gap do you have?
IIRC I adjusted mine to give me ~1" of gap. I went a bit low at first (could barely fit my finger in the gap) and it was hitting the bumpstops way too easily on things like speed-bumps. I'm a happy camper now. Much lower than after I got it back from the clunk tsb, and a better ride as well.

 

Is it hard to adjust. The truck needs to be jacked up right?

 

Not hard. You don't need to jack it up, just get the rear up on ramps.

Search for a post I made on this a while ago. You need to adjust both sides. Two ways: loosen the little nut & slide it up in the adjustment slot (for larger adjustments), or loosen the locknuts on both ends of the micro-adjust bolt/wheel/thingie ( ) and twist it to effectively shorten the arm. Both methods work. I had a hard time getting the locknuts loosened on the adjustment bolt, so I went w/method #1.

 

Very nice!! I just picked up an 04 and love it. I have been noticing that the rear is a bit stiff as it seems to hit the bump stop a lot. I will definately look into adjusting mine. Thx for the thread!!

 

Let us know how it goes.
