Newbie 10 Bolt Questions

[bigred85]

I am at your mercy! /forums/images/graemlins/bow.gif /forums/images/graemlins/bow.gif

I know that I am blind, so am I just overlooking the fill plug on my rear 10 bolt?

How much oil do I need to get to refill it??

What kind of oil do I get???

How do figure out what gear ratio I have once the cover is off????

What RTV stuff should I use?????

I guess that's all for know.

Thanks,

NS

PS. ck5ers are the greatest!!!!!!!

the fill plug on a rear 10 bolt is on the passenger side in front of the axle, about 1/2 way up /forums/images/graemlins/waytogo.gif
I also use 80w90 gear oil.
to find the ratio you take the #s off the main ring gear(may have to turn the axles till they come around) and you can post up and someone will tell you..
good luck

I use Ultra Grey RTV for those. 80-90 for normal weather 85-140 for hot climates.

For the ratio count the number of teeth on the ring gear and then count the number on the pinion gear. Divide the ring number by the pinion number and that the ratio.

What is considered a "Hot Climate"??
Dallas is nothing like PHX (where I heard it was 112 the other day), but we do have our share of triple digit summers.

Also, do I need to relieve the pressure on the axles with a jack, or can I leave it on the ground? /forums/images/graemlins/dunno.gif

Is there anything else that I need to be looking for while I am in there?

 

[Hossbaby50]

to turn the ring and pinion to count the teeth you will need it off the ground but that is the only thing you need the tires off the ground for.

running the heavier oil isn't going to hurt anything I don't think. If you have a govlock you will need to add the limited slip additive to the gear oil. You can get that from GM or some parts stores might have it too.

How do I know if I have a Govlock??

Give me a break, I am new to this sort of thing!!

 

[Hossbaby50]

look at the tag in your glove box. If it says G80 or locking differential on the options sticker then you have a govlock.

When you open it up if it looks weird in there and isn't just 2 side gears and 4 spiders in the carrier then it might be a govlock also.

Just so you know, the square opening on the fill plug takes a 3/8" ratchet (or 3/8" extension).
