ACDelco GM Original Equipment 10-4003 Limited Slip Axle Lubricant Additive - 4 oz

Strange jiggly creaks were coming from the rear end of my 2021 Tahoe Premier. Thought there was something wrong with the driveline splines or something even more expensive. Found out that I needed to change the rear differential fluid. (Should have done it at 30,000 ideally). This along with two quarts of GM SAE 75W-85 synthetic gear oil took away the squeak.

Works as it should

GM stopped making and stocking everything for this car. It's extinct. Parts are sparse. But gratefully this little bottle of magic still exists, and is affordable! Change your rear diff fluid every 18-24 months or every 15-25k miles if you own an 04-06 GTO. The LSDs are a metal on metal "cone type" design, so the amount and quality of FM you use is critical, as is flushing the fluid frequently to excrete metal slush in the diff housing. A quality 75W-140 gear oil works very well. Start with 2oz of the modifier, then ~1.5-1.8qts of the gear oil. Drive the car around for a while and listen to how the rear end sounds when turning and performing slow-speed maneuvers in parking lots. Add 0.5-1oz at a time to tune the diff. Let me know if you found this review helpful. 👌 🍺 ✌️

Put this in my 2021 GMC Yukon Denali rear driveline oil when I changed it out and it took away the low moaning noise we had while turning! It is a must for 2021-2025 Yukon's and Tahoe's in rear driveline oil.

Perfect!

It is what it is. And its what GM says your supposed to use. so...Warranty satisfied. Gm's happy, im happy. I saved $300 doing the transfer and differential fluids myself. In my driveway with simple hand tools. And it only took 1-1/2 hrs. WARNING TO ALL! Make sure you can access the FILL PORT BEFORE you drain your fluids! Make sure you can fill what you just drained!!!! Or you are stuck. Best luck to you all. Check that fill port!

I ordered this for rear differential oil change for 2021 Yukon Denali. We didn't have any big complaints to solve for noise from limited slip differential, but used it due to you tube videos, tech bulletin etc. Also, helps add fluid if you are only ordered 3 total quarts Gl5 fluid for front and rear differential, so makes sure you have enough, which I did. No issues w/ noise after installation but this job done in July.

Best price for the A/C Delco product.

信頼できるOEMメーカー品で安心して使用できます。

Works good

works fine

トヨタ、６０ノア ダイハツ、アトレー７ の４ATに使用したところ、変速ショックがほぼ無くなりました。 今のところ副作用はないですね。 トルセンLSDの、ようなギアの組合せ機構で効果があるなら、変速AT(4速)でも、通用すると 睨んでの使用。 まぁ、用語、構造が解らん人は試さないでくれ。 責任持てんのにゃ。
