Most everyone that owns a GM truck knows about the infamous yoke clunk. After putting up with it for the last few months on my extended cab, I decided today that I would fix the issue. After doing some research, there seemed to be three ways to go about fixing it: getting the updated nickel yoke from GM, packing the current yoke with grease, or clamp the leaf springs. I chose the third option due to ease of installation and adjustment. What you'll need: - Leaf Spring Clamp Kit (2 pack) Part# 13-1401A from AutoZone, O' Reilly's, etc. Should be the same in each store. ($15-$20) Located int he towing/trailering section of the store. - 19mm deep socket Install time: - Less than 10 minutes Where do the clamps go? - The clamps mount approx 6" in front of the rear axle What does this accomplish? - By clamping the leaf springs it helps to prevent the rear from moving when you are driving, effectively eliminating the "clunk" noise Pictures of the clamp kit you'll need: Installed Tightened down Visual distance from rear (estimate, no need to be exact) And there you have it. This quick fix eliminated that annoying clunk while driving. Hopefully this simple guide can help others that are wondering about this fix.
