How To Change Rear Axle Seal On 2007 Chevrolet Suburban

Well, assuming it's a 1999-2003 GMC or Chevy pickup/tahoe/yukon, etc:

Front end axle: 3.5 pints or one.75 quarts

Rear beam: 2.one quarts claimed, will agree 2.7 quarts

Total gear oil: Go 5 quarts

AutoTrac transfer case: two.3 quarts, so y'all will need 3 quarts

You demand a synthetic for the rear axle, at that place should exist a tag side by side to the fill plug stating so. The Goodwrench Synthetic 75W-90 is like $24 / quart. A substitute is Amsoil gear oil 75W-90 (Virtually $9/qt) or Mobil 1 75W-ninety gear oil ($5/ qt). If yous have the G80 GovLok rear axle, it wouldn't injure to put in a tube of friction modifier, something like CRC Trans-X PosiTrak LS additive.

The front beam needs a 80W-xc GL-5. At that place was a TSB a while back warning to use a synthetic 75W-90 if the temps driblet below -5 F in your area. I would run a constructed in the front axle anyhow for amend wear protection.

Note: yous may want to take the rear cover off the beam to make clean the magnets off. Depending on how many miles you have on, especially if this is the first gear oil change, there will exist a lot of filings on the magnets. Fuzzy filings are normal, chunks and actual pieces of gear are NOT normal.

You lot may want to remove the slip plate, if equipped, to make servicing the forepart axle easier. The front axle drain plug has a magnet on it, and I bet it volition be full of blackness sludge and heavy filings. Mine was at but 600 miles! If it makes you lot experience better, refill with a cheap 80W-ninety like I did, drive it a few days, and drain over again. Go along doing this until the magnet stays make clean, then refill with your gear oil of choice.

You lot may desire to invest in a gear oil pump of some sort, the type that screws onto the bottle of gear lube, to make filling the forepart axle easier. I have pails of commercial constructed gear oil effectually my shop, so it'southward too piece of cake for me to just put the fill nozzle into the fill up pigsty, give the pail pump 2-three pumps, and it's full.

If the AutoTrac fluid drains out red (Older mill make full) or appears dirty, the replacement AutoTrac Ii fluid is bluish and has college detergents. Wouldn't hurt to drain and refill over again after a week or so of driving. MoutineerTom has excellent guides on the gear and autotrac fluid change, wait at the left frame of this forum nether "Guides."

FWIW: I did the initial service at 600 miles: Front and rear axles, trans, and autotrac. Afterward towing the first time, did the rear axle 600 miles later. Did them again a year after with about 12,000 miles on it. The supplemental GM GoodWrench SmartGuide suggests initial axle service at 3,000 miles, and so every 12,000 miles. If you tow for the offset time, 600 miles after.

Why practise yous want to buy from this dealer if they don't even know how much fluid it holds? YIKES!
