noticed a leak from the rear axle, was just going to replace the axle seal then looked inside the shaft and seen this. its rubbery and its behind the bearing. all the videos and pictures of the bearing dont seem to have this attached, ive looked looked and looked online and cant figure out what it is, kind of looks like it goes down in the axel housing a little maby like a rubber sleve or seal.   Anyone know what this is and what the part number is, i cant find it in any diagrams.

When looking for help with something, a year and model would be a good place to start. It looks like the reluctor ring for the wheel speed sensor came apart.The bearing has to come out and then the reluctor has to be replaced.You need a slide hammer for the bearing and reluctor and a special installer to drive the new reluctor into the tube.Was some one else in there before you? Thats not a common problem with that rearend.Can't give a part number with out the year and model, is it an 8.5, 9.5 ? vin number is always helpful.

Sorry about that, could definitely see how a year make and model would help.

 

Its a 2009 chevy tahoe vin 1gnec23359r272560

You referred to a special tool to drive the new reluctor into the tube. Would a bearing installer work. Or could you point me in the right direction for this special tool? Thanks for all your help.

I am pretty sure you could come up with something that will work, We have special tools for everything at work but not always needed, maybe a deep socket or a piece of pipe. You need something that fits the outside diameter of the reluctor and deep enough to drive it into the tube, should be a stop so it cant go in too far, but check for sure when you get the old one out. If not set it in the tube so the teeth line up with the center of the speed sensor hole and you should be good to go.

I just had to replace this due to replacing the wheel bearing and damaging it. I am having issues with ABS and tractions control. Basically the reluctor rings are able to be turned by screwdriver from the sensor hole. I have driven it about 15 miles and it is still the same. How long until the black stuff inside the new reluctor sets on the axle and makes the reluctor turn with the axle? 

HOPING not to have to take everything back apart!!!!!

      Wiring Help, Please

      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. 😉
