Popping noise coming from the rear

2013 Toyota Tundra 2WD Extended Cab 4 Door 5.7

I need help, losing my mind.

Back in April of this year the center support bearing decided it was going to quit its job. No 2 week notice or anything, just broke while attempting to leave my drive way. Tried replacing it myself, didn’t go well. Took it to the local shop since I didn’t have more time to deal with it. They call me later the next day to tell me I bent one of the holes that the U Joints sit in so the new u joints won’t slide in. Shop recommended I order a new drive shaft, I told them to go ahead. Well, well my wife picked up the truck cause I was out of town working. Got home and we took the truck to town about 20 mins away, no issues. About a month or so sgo, I was driving around with my 3 year old with the windows down and noticed that when I let off the gas while above 50mph, it sounded like a coke can rattling in the rear of the truck. Brushed it off as maybe there was a can in the bed of the truck. The following weekend the wife and I were in town and I had my window down and noticed the same thing again, but it was more frequent. Almost every time I left off the throttle while above 50mph it sounded like a coke can in the back again. Got curious, but still brushed it off. A week or so later I decide to clean the cab & bed of the truck out completely. Emptied the tools box and organized it. Let all the windows down and opened the rear window and went for a drive. Again, above 50mph when letting off the throttle to just coast either up hill, down hill, or just letting off to slow down without pressing the brakes, it sounds like a freaking can rattling around. Doesn’t last long each time. But definitely noticeable. Doesn’t happen while pressing the throttle. Doesn’t happen when pressing the brake peddle. Only when you remove your foot from the gas pedal. Crawled under and inspected the center support bearing and drive shaft. All looked good. Ordered new brake pads, rotors, calipers, & shocks for the front and rear. Ordered new upper control arm, lower control arm, stabilizer links, inner and outer tie rods since they needed to be replaced anyway and it was just more I can rule out. Checked diff fluid level, it’s good. Can’t check transmission fluid level due to no dip stick. Haven’t found anything that would be a smoking gun or anything that looks like it needs to be replaced soon but the noise is getting more and more annoying. Would like to get this fix asap as I’ll be putting about 100-150 miles a day on it for work.


Any suggestions will be appreciated
