When you break the g80, will it lock at all? Or, do you just have a peg leg? Mine is screwed, and I am just guessing what is wrong with it before I open it up. I can still spin both tires, but it is making a bad clunking noise. Also, when I turn to the right it makes the noise over and over until I am going straight.

 

Mine make a loud clunking noise.Sounds like it's time for a Auburn Pro or an Eaton posi.

 

Sounds like some teeth missing.

 

I have a couple go and they sort of clunk. One of mine split in half, whole carrier f'ed. Funny thing is I have 1.51 60ft'ed the one in the 96' and have still yet to have a problem one.

 

Thats what I was thinking, we will see tomorrow.

 

auburn seems to hold up pretty well stupidfast has had his since his first motor and hes been through four and it just now broke so i give it my seal of approval

 

If I heard those noises, I would stop driving the truck and change the unit ASAP. I heard these same noises, exept when mine broke under normal driving conditions, it took out the rear end gears abd bearing. A $500 job turned into a $1200 job. Do it before its too late, trust me.

 

I drove it home and parked it last Wed. Why would it cost 1200? I can get an Eaton, gears and Master rebuild kit for 540.00.

 

ya, might have to open her up and see what is floating around in there

 

Eaton, Master Rebiuld Kit, Axle Bearings, and OEM Gears were 725 plus the labor. If you do it yourself, I guess you would be able to do it for the cost of the parts. I don't feel comfortable adjusting the mesh between the gears.

I could have spent $540 as well. I bought OEM gears which were like 125 more I believe and another $75-100 for axle bearings. My rear end had a lot of metal in it and was afraid the metal went into the bearings. OEM geras are less prone to whining and making noise.
