Rear End Lube Question
OK - while the car is up on jack stands and I'm scratching my head about the left rear wheel (separate thread), and everything is good and warm, it seemed like a good time to change the oil in the rear end - which i've been putting off for some time.
I had 2 bottles of the GM lube and 1 bottle of the limited slip additive. From the threads I've read, and the manual, I expected to have the rear end full before I finished putting in the second bottle. It isnt. Now, I'll be honest, there was some that made it to the garage floor instead of the rear end, but not that much. Is this common? (not the deal with the floor :D , but the rear end not topping off) The label on the GM lube says its 80w90 GL-4. Can I top it off with another brand of this, or do I need to get the GM stuff? I ask because I dont have a local source for that. |
I bought 3 bottles and have 3/4 of the 3rd bottle left.
I would buy another.:ack: |
Me too, just did mine today 2 & 1/4 bottles and 1 posi add.

To my understanding, U'll need 2 additives:

80w90 GL-4. Can I top it off with another brand of this My owners manual has the capacities in the back, including the differential. Got one of those? (owners manual) I have a vague memory (most of my memories are vague) of GM making 2 different sizes of the limited slip differential additive, which can make it a little confusing when you are trying to figure out how much additive to add. |

Also, one can use a 50 cent snorkel funnel from Walmart to attach to the oil bottles to fill it up. Like this: http://img686.imageshack.us/img686/5622/dsc02477j.jpg Enjoy! |
I had a 'date' with to take my granddaughter on a cruise today - which I wasnt going to break -- so I topped it off with some Royal Purple. No problems. I will probably change it again in a few weeks. I know there are some that may say it is unnecessary - but what came out of there was pretty nasty. Next time I'll have the third bottle of the GM stuff and not have to worry about it.
Thanks all :cheers::cheers: (Oh yes - a 3/4" socket works fine) |
