Default How to replace clutch packs in a 9.75" limited slip rearend that shudders

youtube video I made of how I did this.

took me 3 days in the afternoons while dealing with the heat/mosquitos/rain.

*notes*
1. you do not have to remove the differential
2. you will need a friend to help get the spiders back in
3. my cost for this was $105 to get this done after I returned the extra
fluid and my "tool".
4. soak the clutches overnight in friction modifier
5. c-clip pin bolt torque is 20ft/lb
6. use new clutches/block plates from whatever kit you buy

I know Im probably not covering everything so ask questions

you need to absolutely bottom it out. You also need at least 8' on your breaker bar to get enough torque to move those gears back in place. I would also recheck both of your clutch packs and make sure you dont have anything extra in there and make sure none of the old shims were still inside the carrier.

when I say it is REALLY tight, it is REALLY tight.

I was able to get it in the next day on my own attempt. Made sure "The Tool" was in there and opened all the way up. Truck was in neutral, i had a 3 foot bar in the driver side wedging that assembly from rotating. While on the passenger side with a 3 foot bar, I was able to slowly walk them in. Took some patience and a roll of masking tape to hold the gears in as I did not have the third hand...

gotcha, yeah having another set of hands made it a lot easier for me. out of curiosity just how much extra thread were you able to go on the tool on the successful attempt vs the unsuccessful ones? mine was considerable lol

I wasn't able to get any extra thread in, the difference was using the long bar to spin the axle and walk it in. Truck is amazing now, much better
