Changed my 4x4 hubs 3 weeks ago. Took about an hour. I used grease on the splines, Loctite on the axle nut and tourqued them. I had what sounded like an old school speedometer cable noise that I couldnt find, it did this for 30k miles or so. Then the left front bearing stsrted to interminnantly make a grinding noise. I checked and had no play in the bearing and could discern no noises with the truck in the air. I ordered what I thought would be USA made hubs but turned out to be China made.
When I got them off the left front felt a bit grindy. Replaced them and all noise was gone. Will see how long they last.
I was a Mercedes line mechanic about 20 years ago. Did that for 10 years then got wise and went back to school. I kept all my tools so have a bit of an edge there.
I just today lifted the truck with replacement torsion keys and rear shackles. Gotta get shocks and tires now. I was going to waith to lift until I needed tires but I ran over a stone in the woods that somehow went through the side wall.
