• broken open diff..

Posted: **Sun Apr 08, 2007 1:45 am**

..So my car is on jack stands, and I thought it was something to do with the tranny. I replace the tranny with another and new slave and all that jazz and attempt to drive my car. However the driveshaft just spins, so then I take off the back case cover on my open diff and find a broken gear, both halves of it are laying inside. My question's to ya'll are:

Is sliding in an open diff (or trying too..) harder on the diff than if you were using a limited slip?

Does anyone have a writeup on welding a diff?

What does it mean when people say they have 25% lockup, someone told me quite a bit about lockup awhile back, but I forgotten.

How many people are using:
-Welded diff's
-After market diff's
or....
-oem LSD's?

Thanks in advance!

most of the people on here have 1.5 or 2 way clutch pack diffs. a few have welded waiting to change to clutch packs.

Go for a KAAZ all the way.
Worth every cent, and then some.

Kaaz just makes a 1.5 way for BMW's, is that any better or worse for drifting?

http://en.wikipedia.org/wiki/Limited_slip_differential

These explains the difference between 1.5 and 2 way LSDs that will give you a better understanding of what they do so you'll understand what's what etc...

'Preciate it!!

Welded diffs have any other downfall besides breaking them?

tire wear
noises (from tires chassis etc)
considered "harsh"

my kaaz 2 way.

I do just fine with the 1.5way. Only time I ever notice it is if I come in too hot, and have to jab the brakes real quick... and even then - it's noticed minimally. Plus, I'm pretty sure you could talk to Ray at KAAZ and see about a 2-way.

Yeah... $1300 was for my 1.5way for the e46.

That is just for the limited slip unit. Best avenue to take, is get a replacement pumpkin off car-part.com, so you can have little-to-no downtime. Just swap pumpkins, and rock out.

...soo you just get the internals? You think if I called him up this summer he could hook me up with a 2-way instead of a 1.5 way?
Also, should I do a Jstock suspension setup FOERST, or a 2 way? both are very important, but which one would help me the most??
