I told him to check his u joints....

My son's been chasing a whole truck vibration for the last 4 months. Suggested a u joint, but he said they were feeling good. We swapped his ground up rear diff on Saturday and he checked them again and said I think maybe the front one is starting to make noise.

Ya think?

I couldn't figure out a nasty vibration at WOT only on my Roadmaster therefore drove gingerly.

Next up at stops temperature would rise.
Checking tank as no cap on rad and looking for leaks the obvious happened when put my hand on shroud and FAN.
Who knows when it totally failed and associated broken obsolete bracketry not available. Missed the rad by about 1,/4".
95 LT1 fan does not bolt to waterpump but separate BS assembly.
Also did not realize might as well plan on waterpump replacement when tuneup needed.
