Cleaned the inside of the wheelsmon my 3500 as its got a bit of a highway vibration. Not packed but some dirt and dust oddly built up.
Aired the tires down as we are done with the heavy tows and not hitching up for another two weeks. 70psi front and 75 rear. Tows good but a bit "sharp" unloaded.
Seeing as its 166,000km, I pulled the easiest access shock out back. Still takes decent effort to push in but not overly fast on return. At least it returns.... a set of 4600s are in the near future.
Found a touch of ball joint play up front, now on both sides. That too has to be addressed. EMF?
