No easy way to do it...
Pull both halfshafts, unbolt driveshaft, unbolt diff cover bolts to irs frame, unbolt lower irs cradle,.unbolt front diff bolts and remove.
Drop diff from irs frame and unbolt housing bolts. Drain diff fluid and scrape all material from cover and diff. Apply new copper rtv to diff cover and bolt back to housing.
Reassemble diff to irs, let set overnight and add fluid (2qt 75w140 fluid and 8oz friction modifier.
Would be perfect time to upgrade your diff cover or add a diff brace. Also good time to upgrade diff bushings.
