:rolleyes: For a 2004 Yukon 4WD, when are you supposed to change the differential fluid and the power steering fluid? My owners manual does not address those specifically. Thanks.

For any diff 30,000 is a good interval. 50,000 is ok but I like 30. I work with guys that have 15 year old trucks and say they have never changed any fluid but oil. Up to you. I dont chance mine

I change the diff lube every 2 years or 25k miles, cheap insurance. The power steering fluid gets sucked out of the reservoir with a turkey baster every 12 months.

The service manual for my 02 suggest 60K for the differential....nothing on the power steering fluid at all.

Changing power steering fluid every 12 months is nonsense. Also, if you only empty the power steering pump reservoir, you are replacing only a small portion of the fluid.

 

Also, 30k differential oil change is only for severe service vehicles, like those used in heavy towing for example, or severe off roading. 60k miles is more appropriate for normal service.

1- how do you properly replace the powersteering fluid completely?

 

2- I just changed my rear diff oil at 57k and it smelled burnt and was very dirty.. I don't ever tow, but the truck is lifted.

Agreed, you guys are wasting your time and money by changing it every 10 or even 30,000 miles.

What I did to replace my P/S fluid.

 

1) Remove the rtn line at the pump and place the end in a container. Have someone start the truck for just about 2 seconds.

 

2) This should all but drain the resv. on the pump. Fill it with our choice of fluid.

 

3) Repeat this process 2 to 3 times and then replace the hose.

 

4) Fill it up and either drive the truck or simply turn the wheel from lock to lock several times.

 

5) Repeat steps 1 and 2 a couple more times and you should be good to go.

 

 

If you do not drive it or turn the wheel you really cannot get all of the fluid out of the rack or the steering box. There are service centers with equipment that will do this as well but IMO this is a good way to do it in your garage.

 

One last thing. If you do not use a good syn fluid, I woudl strongly recommend adding a bottle of Lube Gard's power steering additve (Part # 20404) when you are finished. Just like their trans products, it is a great additive.

I agree with you that replacing PS fluid yearly is overkill. However, if you empty and refill the PS res every 12 months, you would be replacing about a third of the fluid and I suspect it would stay fresh that way. That's the method I use anyhow.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
