I'm pretty sure my rear end just went out. Its locking up when I turn then makes a loud pop and jumps. Almost like it's in 4wd

 

So I called the dealer ship and they said it's a 3:73 posi. What years have the same rear end? would a suburban be the same? I know the local yard has a few suburban's for $160 and that seems like a pretty good price.

 

 

I'm not going to be able to buy anything new, so I'm going to have to find a good used part. Is there any good interchange programs or sites?

Half ton trucks over a wide range of years the harder part will be matching your gears and brakes or potentially swapping your brakes to the "new" axle if they don't match.

I would start by looking at 1999-2004 half ton stuff.

All 1500 trucks will have the same size axle except 1500HD and AXN. Its an 8.625 in. Just be sure to get a G80 axle and disks if you have em. Before you buy at the junk yard its a good idea to pop the cover and inspect the internals

G80 chunks might be what is wrong with the current.

How do I check?

 

I was wrong and the only rear end I can find is $550. I found a 2500 frame for $400 though.

It's at a friends house, he hasn't really looked at it yet because it's going to be a week or so before I have the money to fix it.

To check you open the cover and see what broke.

 

I'm pretty sure that its bad. For some reason one of the shock mounts is bent, the rear drive line was moving around so much that it was rubbing against the muffler so it was moving at least 4 inches, it makes a loud poping sound when I make any turns and then the whole truck vibrates and shakes when I'm going straight.

 

Would the rear end from a tahoe work?

I don't think I'll find a rear end very soon, is this a common problem??

Drove it around without the rear drive line and it still locked up really bad, almost didn't want to move at all, sounds like it's skipping or shearing teeth.

 

Getting a used rear end next weekend.

 

 

Anything I should watch for next? The transmission feels good engine is pretty strong, new throttle body, alternator, fue pump, radiator, drivers side hub assembly and some other small stuff.

 

What's most likely to go wrong

next? It's a family owned truck (I'm the second owner) and it has been well maintained.

 

I'd like to be a little more prepared for whatever goes bad next.

Clay be sure to inspect the dust shields on the new axle because sometimes their bent and rusted and make a lot of noise and you'll hate it. Also its always a good idea to inspect the differential with the cover off before you buy it, just to make sure its not damaged or has lots of metal shavings

75-90w amsoil gear oil. NO additive. Replace the gasket too. But take the fill plug off first

The amsoil Severe Gear 75-90 is supposed to be pretty good.

 

Probably will do the transfer case fluid too. That's the auto track II stuff right?

only gm autotrac fluid. No other company makes a substitute. Gm has additives in that fluid that no other adds

Do you mean for transfer case or the gear oil?

 

Found one for $100 out of an 05, getting it tomorrow.

      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. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
