This is what mine was doing.

If I was a betting man, it’s the same issue outlined in the thread below. I’ve had this noise since day 1 with my 2015 (almost like a rattle snake noise from the footwell under acceleration). Followed this fix this weekend and the noise is completely gone. Worth a shot.

Yeah, still running the stock Ranchos with 53k miles on them. I’ve got a set of Bilstein 4600s in the garage waiting to swap out.

Did this today, awesome fix. Drove around for a while with the windows up and radio off just to enjoy the silence!

I agree with you, seems like they shouldn’t be wearing like this. I’ve had the alignment checked by two different shops and suspension components check out OK as well. Basically been told “it is what it is” and “that’s the nature of the tire.” Sent from my iPhone using Tapatalk

Yeah, I’ve been doing 5-6k. The front seems to have a bit of chop that develops, I think more frequent rotations would help combat that.

Not sure about your tire size, but I have 17” duratracs on my Sierra, and the C-load LT tires seem to have similar specs as the P-rated (load, max psi, etc). I wouldn’t put an E-rated LT tire on my 1/2 ton, but I also don’t do much hauling. Whatever you decide, be sure to rotate every 3k miles. Mine have a bit of scalloping wear even though the alignment is good.

Wise choice on the zip ties. Mine are just sandwiched between leafs and after a month or so I can see they’ve moved a touch.

How did you guys reach the third nut behind the brake booster? I can’t seem to find a good way to get to it.

This thread went off the rails.

What size/material tubing are you guys using? I have the AMSOIL hand pump to pump fluid from quart and gallon bottles. Would this work with a long section of tubing down the transmission fill tube? Sent from my iPhone using Tapatalk

I was unaware that they were different. I'd have to see a picture of the 16-18s.

This is with the Mobil 1 LV ATF HP? Sent from my iPhone using Tapatalk

I jacked the truck up from the frame letting the rear axle hang. Used a pry bar wrapped in a towel to prevent any scratching and a wood block wedge to separate the leafs. Cleaned them spotless, cut the bike tube to appropriate size, slid them in, took out the block, removed the jacks. There are insulator pads between the two leafs, I put the rubber on those. The front side of the spring pack has a collar that helps keep the rubber from moving laterally. The back doesn’t but they haven’t seemed to slide anywhere yet so we’ll see. Biggest thing is cleaning any grease or lube out so they’re dry. Even if I have to redo them twice a year, easy and quick fix. Sent from my iPhone using Tapatalk

Mine rear end noise was getting really bad. Driving across a field it sounded like the rear end was going to fall off. Scrubbed and cleaned the leaf ends with brake clean to remove all grease from the dealer, inserted bike tube strips, quiet as a mouse. Been 3 weeks now and they haven't moved a fraction of an inch. Seems promising.
