Hum

As soon as I start cold I get a lifter click from oil bleed off and within seconds it quiets down. When hot there is diesel chatter. I am worried however regarding vibration above 57 mph to 70 mph. I am paying out of pocket $25.00 per front wheel to have balance under load of each. It feels like balance issue to me. I will come back tomorrow night with answer. If that does not fix vibration I will be very unhappy driving back to Florida with that issue because those speeds are my towing speed of TT weighing 7250 lbs! I usually tow at 65 mph and shake bothers me a lot. Below 57 is not practical and above 70 is not either for sure.
