I'd think brakes.Pull the wheels and take a look. The rear has no hub bearings like the front. The bearings are lubed from the differential fluid. Doubtful that would be the problem, but could be. Have the brakes thoroughly looked over

I don't know if it's the bearings I did the front wheel hubs 5000 miles ago is it time to do the back it only has 80000 mile for a 2000 I hear aloud high pitch sound as if I were stopping at a stop light with bad brakes but when I'm still rolling and off the brake.s so is it my bearings going bad I checked my brakes 1000 miles ago and they were still in great shape if some one could point me in the right direction that would be great thank you

Grinding noise? Humming noise? Speed related? Only when braking? Whats diff fluid look like? Any metal on diff plug?

00 had the rear discs?

In all the RWDs I have had, cars and trucks I have never had rear bearings go.

My 01 with the rear calipers sometimes I would only 12,000 miles on them before pads and rotors were eaten up. Problems with the emergency brake set up too, pads and seizing cables. It is an easy check, jack it up and pop the tires off.

Disc brakes have squealers, little metal tabs which indicate when the pads are done. Discs don't retract the same as drum brakes so once they get way down it won't matter that much with your brake pedal pressure, they will squeal.

Depending on when the noise appears and type of noise, also look into u-joints

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
