Front End Thud

[Annihilator]

Hi guys, I just installed a set of KYB shocks in my '00 Z71. My original shocks had 140k on them and I thought it was a good time to replace em. My questions is, when its cold out, and i hit a pothole, my truck hits pretty hard, almost as if the shocks aren't doing their job. It also has new tires, tie rods, idler/pitman arms etc. My balljoints may be original but they look ok. My friend's '04 Sierra Z71 doesn't hit as hard but he's only got 70k. Ideas?

Just to add, the shocks are the mono-tubes recommended for my Z71. The OE shocks hit hard too so that was part of the reason for swapping them out.

i was hearing a yhud in my front end. my hub bearings went bad. jack the front up and see if you have play in the tire

i get a thud too and i dont even have hubs (2wd) new shocks also...i think its the stiffness of monotubes

Have you had the wheel bearings checked lately?

Cold shocks are usually stiff until the oil inside has a chance to warm. Cold shocks, cold steel springs, cold stiff tires, and frost damaged roads...winter is hard on vehicles.

Bearings are fine. I never had a truck before with HD suspension so maybe thats just it.
