At around 40,000 miles, I began noticing a clunk in my steering. I now have 99,900 miles on the truck. During this period of time, I have replaced the ball joints, trackbar, (2) tie rod ends, stabilizer, and shocks (all due to wear). Through all of this, the clunk has never gone away. After having (2) intermediate steering shafts replaced under warranty in my wife's 2002 Tahoe lately, I was sure that the same part was bad in my truck. Installed Borgeson shaft this weekend. Can't believe how much tighter the steering is now!
Problem is the clunk is worse than ever.
I realize that the shaft, being much tighter than OEM, makes it FEEL worse. Having narrowed it down by process of elimination, the only other possibilities I can come up with are front axle u-joints or steering column. How do you check both these and has anyone ever replaced the actual steering column (I'm nervous about tearing into it)?
Another problem that may or may not be related is a loud knock that I can feel through the floorboard. It only occurs when the road is wet. If I turn the wheels to the left, for example, it will knock but won't do it again as long as I keep turning left. As soon as I turn right, though, it will knock and won't do it again as long as I keep turning right. As soon as I turn left... ... ... ..... so on and so on. Just started doing this recently. Both problems are driving me NUTS.
