Default Help Question!

I know this is an old question but what do you recomend I replace the rear end fluid with. One archive thread said AmSoil Severe gear 75w90.
GM says Dexron LS Gear oil #88862624. I have the clunking noise when backing up or sharp turn when cold. Thanks for any help!

I used Amsoil.

Both 'solutions' work.
