rear differential still leaking after gasket replaced
98 k1500 suburban rear differential was leaking so I removed the cover, drained the oil, replaced the gasket, reattached the cover, & filled with gear oil. Tightened bolts to 30 lbs with torque wrench. And….still leaking. Leaking worse! What did I do wrong? Any advice, help?!?! Used

used conventional STP gear oil
Thank you for the reply. I appreciate the help. I did not use synthetic oil. Used this STP gear oil. Any other thoughts? Anyone out there think it is a bad gasket or have another recommendation?

leak pics
Thanks for the reply tech2. Here are leak pics. Seems to be coming from the bottom. I did clean the surfaces, used parts cleaner and also scraped off the old gasket remains. Seemed more like a rubbery goo than a true gasket. I read elsewhere to only scrape with a plastic tool. I did use a metal scraper and a screw driver. Did I damage the cover? If so how to remedy? Anyone think I should try Blue Devil Oil Stop? Redo the gasket with a sealant gasket maker as well?

Thanks again to all who have replied. I am curious about the possibility of a bent cover. I don't think it is, and I know I didn't have to pry hard to separate it when I drained it the first time. I think I will drain it and use RTV...hopefully that will settle the problem. Anyone advise against replacing the cover?
