2001 GMC Sierra 1500 Q&A
2001 GMC Sierra 1500 Question: Can someone tell me what is making the horrible squeak when I hit the gas?
THIS NEEDS TO BE LOOKED AT TO BE SURE.SEEK DIAG AND EST - globalhelper
COOL VIDEO AND GREAT IDEA!!! THAT IS YOUR UNIVERSAL JOINT(S) MAKING THE NOISE, NO DOUBT!! I'VE HEARD IT A THOUSAND TIMES, IT SEEMS LIKE!! START WITH THE REAR SHAFT, THAT IS WHERE THEY USUALLY FAIL. PULL THE SHAFT AND FLEX EACH JOINT, YOU WILL FIND IT. IF NOT, LEAVE THE SHAFT OUT AND DRIVE IT IN 4X4, for a short distance only, like in the video, as fluid will leak out, THEN SEE IF THE NOISE IS GONE. THAT WAY YOU WILL KNOW FOR SURE!!! - pushrod
