I came across this on the net via Ebay and it's an article on Subaru LSD's

and LSD's in general and how to tell if your Diff / Differential is an LSD or not

without having to take the cover plate off.

I'll be going to my locker tommorow to run this test on my

4.36 R180 to see if it's a LSD or not, I Hope It IS !:classic:

Heres the link,

very helpfull info and Junk Yard LSD Hunting Guide as well

Some will find it helpful but I already knew that. I had a Subaru clutchpak lsd in the last 510 I owned. The ratio (3.7) wasn't that great especially with a 5 speed but I could cruise all day on the freeway with that setup but I always had to shift back to 4th or even 3rd to pull a hill.

I had a Subie LSD in my LZ22-powered '68 510. It was an easy swap but I agree with Steve, the 3.7 ratio was 'just okay'.
