So this weekend I will be going to the junkyard to find a 10 bolt differential for my Camaro. Most of the cars (fbodys at least) in the junkyard are missing the motor, so what's going to be the best way to identify if the car was an ls1 or not? Also, what will be the best way to determine the gear ratio of the diff in the car? aaaand lastly, what all tools will i need to bring?

Thanks!

Probably the best way would be the rpo codes

You know how an LT1 Camaro/Firebird looks compared to an LS1 Camaro/Firebird, right...?

Like 6898 said, look at the RPO codes (on the end of the driver side door).

For the gear ratio look for RPO code GUx (where x is a number).

Or look at the VIN:
- 8th letter = engine code: G=LS1.
- 10th letter = year code: W=1998, X=1999, Y=2000, 1=2001, 2=2002.


Which yard are you visiting...?

I meant telling the difference between V6 and LS1, not LT1 and LS1.

But V6's have different ratio's and diffs, no? (i dont know **** about the v6)

Check the vin for G as the LS1 engine code. That will tell you if it was a v8 car.

the v6 cars usually came with an open differential so you'll need to find one with posi. also the standard ratio for a v6 auto is 3.08 and optional 3.42 for the 5spd it only came with 3.23's.
On the door code look for g80 that means it has posi, then gu4 is 3.08 geras, gu5 is 3.23 gears and gu6 is 3.42geard

If you have traction control (i.e with 4 channel ABS) you also need to see RPO code NW9.

look for the 150 cluster

Good info guys, thanks!

Anyone know what all tools I will need to pull it?

joecar

Do you want the whole axle (including abs subharness, brake lines, parking brake cable)...?

wrenches: 8mm, 10mm, 12mm, 14mm, and maybe 16mm
sockets: same
rachet
breaker bar (just in case)
hammer (to push bolts out of lower control arms)
large diagonal cutters (to pry bolts the rest of the way out)


off the top of my head:
undo electrical connector from chassis just in front of axle (driver side, inboard from wheel well)
undo brake hoses from chassis just in front of axle (next to electrical connector);
undo parking brake cables from just behind transmission;
undo driveshaft straps from yoke;
undo sway bar from chassis (will they throw in the sway bar?);
undo panhard/track bar from axle;
undo lower end of shocks (watch out, axle falls down, springs fall out);
undo lower control arms from axle;
pull axle backwards (torque arm slides out of bushing at rear of transmission, pulls transmission vent hose with it);
remove torque arm if necessary.

awesome! thanks!

yes, i'd be getting the whole axle, minus the calipers, so i'd remove those and leave them hanging

You also need am 18 mm wrench for most of the suspension components

nik1703

Am I going to need to replace any suspension related bushings?

I'm gonna say 85 percent of the cars you'll find in the junkyard are v6 cars but you could look for the Z28 or SS emblems. And look for a hole in the floor to see if your a M6 or A4. M6 3.42 A4 273 or 323
