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

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.

Works as it should

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!

Best price for the A/C Delco product.

Used this with GM original rear end fluid to resolve the rubbing noise we were getting with our 2021 suburban. The dealership couldn't figure out the issue but luckily came across a youtube video that listed this additive as something that would fix it.

Rear differential had a groan on cold startup making sharp turns. GM service bulletin for this issue advises to replace the fluid. I learned from some others that this conditioner will work magic on the issue. I performed a drain and fill with this conditioner and a full synthetic gear oil. Problem solved.

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.

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.
