Just checking to see if anyone could shed some light. I have a 4Rnr 4x2 lifted. There's a knocking at the left wheel, and vibrates when I hit 50mph or so. The knocking goes away after 20mph. I'm having a shop look at it next week sometime. Any advice?

We had this problem with our Dodge Ram 1500. Thought something was terribly wrong. We have rims that have a plate that covers the lug nuts. When we were on the way to take the truck in to the shop, it got worse so we pulled over. Some how some of the nuts had broken off and we making a thumping noise and the tire to vibrate.. Fixed the problem in a jiff! :) Maybe it is something that simple.
