I have a 68 chevelle with a 10 bolt rear end
Question:
I have a 68 Chevelle with a 10 bolt rear end. I need to replace the differential cover gasket due to leaking, but there is no fill plug in the cover. How to refill rear end with lube after cover is replaced? Is there a plug somewhere?
Answer:
There is a fill plug that requires the use of a 3/8 extension or ratchet end ( no socket attached ) turn it counter clock wise to remove. it is located on the other side just to the side of the pinion shaft ( where the drive-shaft attaches ) Looks like a square hole.
