Drivetrain Issue

[swettysblazer]

Hey guys. I've got a '91 K5 with a 350 and a 10 bolt rear. Whenever i seem to take off, there is almost like a clanging noise that is happening. It doesn't do it every time, and it goes away at high speeds. I replaced the u-joints about 8 months ago, otherwise thats about it. BTW, I have a 4 inch lift with 35's that have been on for about two weeks... Any ideas?

Check your u-joints, & if they are good check the yokes on the d-shaft for shiny spots. D-shaft could be binding when the axle wraps.
