changed gears LSD

[mule13]

Several weeks ago i went and got another ford 9 inch chunk from an old 70's model ford pickup 2wd.i put it in the truck but couldnt use the 4wd cause the gears were wrong,today i pulled the chunk and put my old gears on.when i had it apart i found it had the ford limited slip unit on it. so basically i got a complete 9 inch rear with lsd for 50$ , i normally run detroits or lokrite lockers which don't require any special oils or additives etc. what additive do i put in this and how much. i've alrady put gear oil in it as i bought regular gear oil not knowing it had the limited slip unit in it. and the 9 inch doesnt have a drain plug.

 

 

Thanks John

Did you set the gears, or just throw them on?

Get a bottle of 'Friction Modifier" from a Jeep dealer and throw in the whole bottle.

i set the backlash and checked the gear tooth pattern.first gear setup i've done really. i watched a few videos on youtube before i started. everything seemed to work out ok i drove it several times and everything seems ok. time will tell i guess.

I have the original Powerlock limited slip in my D60, and I didn't put any friction modifier in it. The way I understand, the stuff just makes the discs slip a little so they don't shudder. I left it out so it grips better. seams to work fine.

It will also wear out faster without the friction modifier.

Agree with eagle. Autozone or similar stores sell bottles of friction modifiers, cheaper than the dealer, the names are escaping me at the moment.

Ya, you guys are probably right.seemed like a good idea at the time. I'd like to put a spool in it someday anyway.
