Shock Question

I have a 2005 1500 Silverado z71 that has started producing a squalking noise in the front pass side when hitting decent bumps during hunting season. This noise can also be reproduced when bouncing the pass front side. It has 99,000 miles. I'm assuming this is the front pass. shock. The truck came with Black and Red shocks. What brand is this? Also, from what I have read Blistens are most peoples replacement choice. I see they make a HD (4600) model and a (5100) model. My ride is stock height. Any ideas if this is the problem and what brand/model to replace with? Doesn't Z71's have gas shocks and would this influence which brand to use? Sorry for all the questions, shock newbie here. I want to replace with what's best for my truck. Thanks.

go to the bilstien web site and put in your vehicle info. the shock # will be revealed. I have the bilstiens on all my vehicles. expensive high quality shocks. go ride quality as well...

the shocks that come with the vehicle should be replaced at 70,ooomiles. off roading these should not last that long. remove the shock and see if its dead.

check other front end components for wear/damage.

I called Bilstein and they suggested the 5100 series 0"-2.5" lift being I have raised the torsion bars. But I need to look to check that that the shock is were the noise is coming from. I didn't realize there are several componets in that area that move.

if you messed with the bars adjustment , and did not follow the procedure that could be something to the noise issue.
