Need some opinions/answers

ok so heres the back story...I bought my 2000 Camaro SS about 2 months ago. The car had 23,500 miles on it when i bought it (now has 24,xxx). I had 2 separate brands of "car fax" reports done on the car to assure that there was nothing hidden that the guy wasnt telling me or anything. Everything checked out fine. The rearend had a humming coming from it when i purchased it, previous owner was an older gent who didnt know when it started making the noise or that it was even making a noise for that matter. The previous owner did however take immaculate care of the car, which is why i found it strange that he had never addressed the humming coming from the rearend. So today i took the car to a shop that was referred to me by a friend who had work done there. The shop has been around for 22 years and seems reputable. The manager took a ride with me in the car and immediately said he could tell that there was damage done in the rearend before he even shifted into second gear. So he lifts it up and says its leaking a lil bit from the pinion gear seal and would bet that the ring and pinion is damaged. So here was his quote...$950+tax for all new seals and bearings, fluids, new ring and pinion gear of my choice (3.42, 3.73, or 4.10 plus he would recalibrate the speedo for free if some place that he has a connection with can do it. Otherwise the recallibration would be up to me to fix. All the parts used would be OEM parts not from china or taiwan.
What do you guys think about this...is this a reasonable quote? Does anybody have a shop that they have had work done that does a good job for cheaper? Also does anybody know what has to be done to recallibrate the speedo? Lastly, what are the advantages of having the 4.10 rather than a 3.42....just accelleration? Thanks.

sounds about right on the price. 4.10 would be like adding a whole new dimension to your car, but yea acceleration

[MP81]

Seems like a good deal. I'd do 3.73s, personally.

[my95z28]

Seems to be a good deal, I have seen 1000 the gears before. I would also do 3.73s if it were me, they are much stronger than 4.10s.

[1qwikSS]

what makes the 3.73 stronger? i was always under the assumption that 4.10 gears were.

Hey Chris,

Just an addition to what I PM'ed you. I really like what the 3.73 did for my car as far as acceleration goes, you'll really notice the difference. My goal was to give it more acceleration without throwing gas mileage in the toilet.

how much did the mpg's drop with the 3.73's?

Guess I should start installing gears. A Motive gear package from me is 294.99 shipped (+Mi tax) Package includes gears, install kit, and gear oil.

well everything looks good quote wise..i would go 4.10 personally since your a m6...also just a suggestion ..with almost 1k into a 10bolt ..why not go with a 12 bolt or a 9" for about 1200 more ? i dont know your driving habits or what your plans are for the car..but if you plan on pushing numbers and even seeing remote track time /launches ..i wouldnt put money into the 7.5 10 bolt

with the rear end OEM parts will be China and Mexico and Taiwan ..just to give you a heads up..so you dont think the guy is trying to rip you off if you look at the stuff before the install

Good call Shady

Genuine GM Part doesn't mean made in the USA.
I can tell you first hand that this is true.

BTW as far as Gears are concerned 3.73's are not enough of a change from 3.42's to warrant the money spent on the swap.
4.10's are optimal esp. for 1/4 mile performance. And fuel mileage will change marginally.

I'm on the 3.73 bandwagon. Like has been said they are stronger than 4.10s. Otherwise do 4.11s (not 4.10) if you arent doing any serious engine mods. I'd personally be afraid of running out of gear in the quarter mile with a 4.xx gear and a modded car... youll go through the gears pretty quick.

6000 RPM with 4.10's in 4th gear (1 to 1) equals approx 112-115 mph
No stock LS1 is going to trap at those speeds so you should be safe
A modded car with the rev limiter extended obviously would have little issues.
On the flip side my stock 3.42 geared car runs through the traps around 106 mph while buzzing a paltry 5-5100 rpm.
Hopefully you can see where I'm going with this.

[JoeliusZ28]

thats why i said a modded car... modded cars will easily trap 115 or so. but i guess you are safer spinning that high with an LS1... i dont want to cross the line at 6k+ in my car.

[1qwikSS]

well my plans for the car with include slight mods for a while. Like i said in the original post, the car only has 24,xxx miles on it, so an engine overhaul is not in my best interest for a while until the engine at least gets worn down a bit and could use an overhaul. Right now im not in the position financially to do anything major to the car. My long term goal for it would be to supercharge it eventually, but that wont happen for a while. i have a BA in education trying to find a job for the past 2 school years with no luck. So i need to get a career and i would prefer to have my own house before i can sink any major $$ into the ride. And as far as track terminology..i am out of the loop! i have only been to the track on one occasion with my previous car club (tri-state muscle) when i had my lt1. So i have no idea what your talking about when you talk about trapping gears and what not. I would love it for someone to clue me in...im always looking to learn new stuff.
