Hi, folks, How should I remove the front LEFT half axle from the differential please? My 2011 Suburban 2500 LT 4WD needs a new seal. I watched some YouTube videos in which some people just knocked it out, but I’m not sure if it’s the same process for my truck. Also, if yes, I’m worried that the C-clip (or the like) will break. Any suggestions are appreciated! Thank!

THANK YOU! Your information is VERY HELPFUL! I think the noise is from the exhaust manifold! I’ll double check!

Thanks! I’ll try and see if it makes a difference.

Hi Folks, Does my engine sound normal? I notice there’s some ticking noise at startup, and it goes away in 1 minute or so. Thanks!

Really? I’m not aware of this as a “fresh”owner. Thanks!

Thank you both for the information!

Is it true that this generation of Suburbans has no service-able fuel filter? I just can’t find a part for my 2011 Suburban 2500. Thanks!

Thank you all for your information and help! Happy Thanksgiving!

Anyone uses non-OEM brands? The OEM brand is not economical at all.

I plan to do the same for now, unless there’ are issues, then it won’t be too late to add friction modifier. Thanks!

Thank you Dave and Mike! mike, I think this video shows how the Eaton G80 works. Seems people still call it LSD.

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!
