At least this Sunday was. Like Andy, I had some fixin' to do. A horrible, metal on metal sound was coming from the left front of The Beast. My earlier suspicion of a warped brake rotor was incorrect, which led me to believe that the problem lay either in the hub or the cv axle. Sigh...
The first challenge is getting the offending wheel off the ground. A six inch lift and 35 inch tires tend to complicate jacking the vehicle up and setting it on a jackstand.
But it can be done, and soon the tire was on the ground, revealing the shiny new brakes I installed last weekend. Rust sure does set in fast in these parts.
Enter complication number one. Just about every fastener on this truck is metric, and the spindle nut (center of the picture below) is extra large. Despite having a tool set which is the envy of all my friends (courtesy of my Dad, the retired diesel mechanic), it's a bit light in the large size metric department. Thus it was off to the parts store to purchase a 35mm socket.
With that dilemma solved, the spindle nut was removed, followed by the the caliper, caliper anchor, and rotor, revealing the hub.
The cause of the problem quickly revealed itself. There was a great deal of play in the hub. The photo below reveals a bearing race sticking out where it shouldn't be.
While this was the more expensive of the two possible problems, it was the one that is considerably easier to fix, by about 4 or 5 hours. Money well spent. After another trip to the parts store, I was ready to put the whole shooting match back together.
Out with the old, and in with the new.
I'm pleased to report that the grinding metal sound is no longer present, and The Beast has once again been restored to her former glory.
On a side note, one socket and one universal joint were broken in the process of these repairs. Thank goodness for lifetime tool replacement.
