Finally got the new diff

[billygoat777]

Hey guys I just wanted to say that I finally was able to by my new 3.64 LSD for $455 and I got a quote from my shop for installation for around $250 labor. Just wondering if these prices sound about right?

[screwbiedoo15]

$250 labor sounds alright. It could probably be done for cheaper but it isn't an awful quote IMO

[Binjammin]

$250 for labor to install a diff? Why don't customers like you fall into my lap every day? Even at $120/hr I don't see how it could take two hours to swap a diff out if you've got a lift.

This shop has a lift and tools, right?

+1, especially in a no-rust place like CA, two hours MAX.

[screwbiedoo15]

Nevermind, listen to them and not me. They know they're stuff

[billygoat777]

I would try to do this myself except for the fact that I have no tools at all, no floor jacks, and I can't lift the diff itself...

I haven't recieved the diff yet but I mean if anyone could help me do it myself I would really apreciate it

I'm 17, never had to take a car in to have anything done so i don't know how these thing's are priced, if they didn't fire my autoshop teacher I could probably do it myself, but like I said I have no means of doing it

Sounds exactly right from a shop. 2-3 hours labor is book time x whatever your shop charges per hour. Just because you can do it in an hour doesn't mean anything, shops have to make money.

Thanks man, all I needed to know was if the price was average

[m60b30530i]

pretty much all shops have a book were it says how long repairs should take and it doesn't matter if there done in a hour they will charge what the book says. now only if Ben could rewrite this book :)

buy a jack and stands for $100, do it yourself.

$250 would buy you a lot of tools.

Tools = savings

[PorscheH6]

Now THAT is a good idea.

Wow, ideas like this never seem to pop into my head...

Hey guys, just wondering what your RPM's would be at 80 in 5th gear with a 3.64?

[Compgeek256]

I have the stock diff (3.46 I think) and I'm at 2,500 RPM at 70MPH in 5th. So I would imagine you would at least be over 3k RPM.

I haven't installed mine yet but I think you'd be around 3200rpms or so. With a 3.46 you're at like 3000 rpms at 80. With a 3.91 it's like 3500rpms at 80 I believe.

[m60b30530i]

how much with a auto with a 4.10 stock is 3.15 at 70 its at like 1500rpm

Don't worry about high rpms with the new diff. I assume your old one was the 3.46 open. When I switched over, there was not an overwhelming difference, so don't sweat it.

+1 for buying some tools and doing it yourself. I just recently did mine with a friend and just had the car on some jack stands. I ended up bench pressing the diff into place while he aligned the drive shaft to the diff input, that was probably one of the harder parts.

Also, I think you told me that your dad was/is Navy, so see if he can get you in to the hobby shop with a lift on base. Though I am not sure what the rules are on use of the hobby shop tools and lifts.

Good luck!

If you try by urslef and fail THEN take it in to the shop and be like fix it..

I wwould at least try

Thanks man for the info

Yea I have a messed up 3.46 open, I never though of using the base as a way to get some tools, so many good ideas, why can't I think up any

Problem with that is, to do it myself I would have to spend money, then if I couldn't do it, I wouldn't be able to pay for towing and for the shop...



Do you guys think a shop would let me watch a diff job be done so I can see how it's done?

[SchnellerE34]

Maybe. With 1 other person manning the e-brake or gear selector I can do a diff swap at my house in less than an hour.
