What is this bark noise I hear when moving from a dead stop in drive? Sometimes you hear it sometimes you don't. Sounds like it is coming from the drive shaft. Definately not a clunk. What ever it is sounds like it needs to be lubed/replaced.

 

U-joints? Slipe Yoke?

Slip yoke. Definitely slip yoke. As it gets worse you will hear it both right before coming to a dead stop and as you take off.

Ok, so what do I replace it with this week? First it is nickel plated yoke then it is not. I just took a look and there is definately some wear around it.

 

Is there a bearing kit or something I'll need as well coming out of the transfere case?

 

What about changing the fluid in the transfere case (or just adding some)? The transfere case seems to have been leaking but none of it ever hit the ground. T-case is all oily looking.

 

I'm thinking that if the Yoke is showing signs of wear then I need to replace the yoke, fix the bearing and seal, and change /add more fluid.

You should be able to just lube the slip yoke and get rid of the noise. This will require the transfer case fluid to be changed.

Going back in tomorrow for a re-torque on my suspension. I'll let them know about it and see if that fixes it.

Just got back and all is fine.

 

The noise is actually axle wrap.

 

Quadrasteer, you would be the winner. Tightening the axle u-bolts my help. Mine were just re-torqued but it didn't help much. Going with the lift actually increases axle wrap as the axle gets further away from the springs. I can either live with the sound or I can buy the traction bars. The guy at the garage told me his does it and his fix is the radio!

I had a 2000 Silverado with the same problem. I had them fix it once and it did not work. The second time they told me it could not be fixed. I then got in touch with GM and they made an appointment for me at my local dealership and they replaced the yoke with a new nickel plated one, this was all under warranty. After the replacement it was silent, with a much better ride. If you complain enough they should replace it. I have a friend at the dealership and a memo went around back in 2000 stating that GM had a problem with the yokes. Good luck.

whys that? I replaced my u joints a few weeks ago and relubed the yoke (huge improvement). Didnt have to change my t case fluid ( I changed it about 2 months prior.) The TSB said to change the T case fluid because in the early model yr trucks they had the red t case fluid. The fluid change was to put in the new autotrac II fluid.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
