The issues I am noticing at 74k mile mark.

These are the issues that I am noticing.
The radio is cutting in and out completely or I loose a function.
Howl coming from the front end, particularly when cold.
Transmission shifts are all over the place.
This truck was used as a tow rig by the previous owners. Supposedly an older couple that towed a camper from Maine to Florida every year.

 

I had it serviced by the dealer a week and half ago. I wasn't worried about the radio, but wanted the dealer to look into the transmission and front end noise. Dealer said they didn't find anything.

 

Welcome to the forum.

 

This a 4 wheel drive truck? That front end noise may be the needle berring in the front differential. Put the truck in 4 wheel drive and note if the sound goes away. This is a common issue and causes no differential failure. It's just annoying.

 

Welcome!

The howling sound may be the fan, they make a loud roaring sound at start up when cold.

The 3 previous owners of my 2007 used the truck to haul & tow heavy loads, and it had some interesting transmission shifting episodes when I purchased it with 270,000 miles. I had the dealer drain down & fill the trans fluid (not the power flush), and then I added a DAP tune. These two things smoothed the transmission out, and I am about to crest 290,000 miles without issue.

Stereo cutting out... my solution

 

I chased a front end howl/growl, womp-womp-womp noise on mine for quite a while (even changed the needle bearing previously mentioned). Turned out to be my tires wearing unevenly. Check your tires and alignment.
