Estaban Which rotors are on the car? 11" or 12". If the rotors are ribbed, they need to pull air through the rotors to help cool the surfaces. I have the Sierra setup on my car. You can wire tie the spinners to the wheels and check them with a little black mark on the spinner and the rim. If they stay tight after a couple of drives, I see no problem with leaving them the way they are unless the rotors are overheating. If the 2 marks move in different directions you will need to remove the assemblies and swap the parts from side to side. If you just want to swap sides, you need to check the bearing races for grooves in the mounting surfaces and the spindles for the same. Regrease the bearing and reassembly. Don't over tighen the spindle nut for the load on the wheel bearings. Use your hand and go snug as you can and then a little more to get to the next hole for the cotter pin. Make sure you split the pin and bend it back to hold. If the rear is the same problem you will have alot more work to do on this. You will need the manual to guide you through this. The wheel alignment may need to be checked after this repair to the car. Where are you? There maybe someone living close to you that can help. Rick L. In NJ.
