Rear end gear oil

How much oil to replace in the rear axle housing. 1 or 2 quarts, or just fill it to the top? What weight oil to use?

Re: Rear end gear oil

Yep. I always use synthetic. Manual trannies & diffs are not something that gets its lube changed all that often. Spent the extra loot on the synthetic!

Fill till it runs out the fill plug as stated above...

Re: Rear end gear oil

Just a note, Eaton recommends AGAINST using synthetic on their posi units.
