I have an 1le aluminum driveshaft and I am going to install it on saturday. I was wondering if I am going to need to add any tranmission fluid to the tranny after installation? Im going to jack the rear-end up as far as I can go, so gravity forces the fluid towards the front of the tranny, and then pop out the DS out of the tranny, hopefully not loosing too much fluid. I was wondering If I still needed to put some in afterwards?

your car have one of the steel driveshafts i take it? I only ask this because i had a guy tell me that he swaped a 1LE shaft with his stock aluminum shaft because the 1LE was better.. it was quite humorous since its the same driveshaft.

you will not need anything for the swap

 

Wait? the 2002's come with a aluminum DS? I have no clue, I just assuummed that it came with a 1 piece steel. Is there a code on the door that could should tell me whether or not it has a steel or aluminum?

Yeah, that's what Dave was telling you, '98+ have an aluminum DS...stock.

 

Not all, I have a '99 Z28, and it's got a steel DS. Just look under there, if it's all rust lookin and stuff, it's steel. If it's clean it's aluminum.

 

if you have a speed limiter then you have a steel one..

 

I seem to remember reading that cars with 2.73 gears have steel driveshafts and cars with 3.23's have aluminum. Is that not correct?

 

2002's ALL have the al. Drive shaft

 

I stand corrected....I guess the 2.73's get steel...sorry!

 

are you talking about an LT1 1LE shaft? those are a larger diameter than an LS1 shaft and a good bit stronger.

Im not sure. here is the part number 10085375, I got it from gmpartsdirct.com for like 219 dollars. I had it in on my 98 v6 camaro.

 

For the driveshaft installation, does one reuse the old bolts at the differential, or replace those?

(the 4 bolts I believe holding the rear u joint to the rear end)

Also, is there a torque spec for these bolts?

 

reuse the bolts, but im unsure of the torque specs.

the 273 cars come with steel shafts, not alum. I got a lingenfelter alum to replace my steel one a while back.

 

2.73 gearing get the steel shaft, others get the aluminum shaft
