  1. Thank you all for your information and help! Happy Thanksgiving!
  2. Anyone uses non-OEM brands? The OEM brand is not economical at all.
  3. I plan to do the same for now, unless there’ are issues, then it won’t be too late to add friction modifier. Thanks!
  4. Thank you Dave and Mike! mike, I think this video shows how the Eaton G80 works. Seems people still call it LSD.
  5. Hi, folks, I have a 2011 Chevy Suburban 2500 HD, 6.0L gas. RPO contains G80, GT4, L96. This is my 1st post on the forum, and hope I’m posting in the right place. Could someone please help me with the rear axle/differential fluid? Owners manual states SAE75W-90 Synthetic Axle lube (GM#89021677, replaced by 88900401). It DOESN’T say anything about Limited-Slip Axle lubricant additive (GM #1052358, replaced by 88900330). However, as shown in the attached picture, ACDelco states the car NEED FRICTION MODIFIER w/LOCKING/LIMITED SLIP DIFFERENTIALS-USE ADDITIVE 88900330; Quantity varies by application. How do you think please? Thanks and Happy Thanks Giving!
