I was getting an odd noise from my rear last week, was like a clicking sound and only was noticeable while turning then it went away. So yesterday it came back and was 10x worse. So i brought it to mechanic and i need to buy a new diff. I was thinking Eaton posi with 3:73, any suggestions anyone? (worst thing is i just washed the car )

You can buy a complete rear, but the problem there is you don't know the condition it's in either. I say bite the bullet, rebuild your rear and have the peace of mind. Oh, and I rebuilt my rear with 3.42s. I upgraded from the 3.23s and I love the extra punch I get. |

Rebuilding is expensive. It cost me around $900 for my rebuild. For a few hundred bucks more, i could've just swapped a strong aftermarket rear end like a 9 inch or a 12 bolt, but whatever. I kinda want to keep certain parts on the car original. Yeah, if you swap rears, try to find either a 9-bolt (they're pretty strong) or an 89 and later rear end with the PBR rear caliper setup. |

Not really sure. Glen had drum rears and he swapped his rear for a rear with discs and 4.11s. The discs were a good idea. The 4.11s were not. I would look on TGO and make sure. I would say yes, but you need to do some extra work. |

>Sure, you can put a disc set-up on a drum rear! You might need to weld new plates on the axle tubes, but people do this swap all the time. Of course a full rear swap is cheaper if you can find a disc rear at the junkyard. Take the cover off the rear, drain the fluid and see how everything looks...chipped teeth, metal in the fluid, black fluid, fluld leaks from seals...all are signs of misuse and needing a rebuild. Of course just a visual inspection doesn't show everything up, ( you can't tell a LSD is bad unless you drive it )but if you want to take a chance and save some money you could go that route. |

With bracing and a good gear set the 10 bolt can handle 650 rwhp. My brother got a lightly used, I mean it looked brand new no wear on the teeth, Detroit locker with 3.42s off of ebay for $300...actually I bought it for him for his birthday. Any higher then the car wouldn't be fun driving regularly because RPMs are too high and your goes down fast. Just build up what you have. EDIT....buy that!!!! |

Are you sure there is no damage to the back wheel? From the way it reads I would be very cautious that back tire is damaged too. A truck hit in the rear.... I don't know |
