8 3/4 dif

People put people in your position...... Just for piece of mind change it out. Just went through this with a 9" ford because the owner wanted "peace of mind lol."

Good luck,

Case in point. Yesterday I de-greased and power washed my engine. All went well and it started right up. After 10 minutes into the drying run I noticed a fine stream of fluid squirting out of the timing set cover. All the crud evidently kept it at a drip for a long time, something I noticed in the driveway. Now I am faced with more down time waiting on parts, tearing the front of my engine down, and all of the aggravation of doing a repair when changing the anti-freeze every 10 years or so could have prevented the corrosion in the coolant passages of the cover.
Not real happy at this point, Jerry
