Cusco Rear LSD install

Postby BADNEWS » Sat Feb 16, 2013 9:49 pm

I posted this in my build thread but I thought I would put it here too.

Took out my rear Factory LSD today to replace it with my new Cusco. I bought the diff brand new from Toyota, but now I have been hearing that people at my power level break the stock one. So I now have a factory rear LSD for sale that has about 2,000 miles on it. lol

Anyway took it out and put the new Cusco in. Monday I'll take it by my buddy who is a tech at Toyota to check back lash, bearing preload, and how the gears mesh. Once that is all in spec I'm going to completely disassemble it again to have it sand blasted to prep it for power coating. Hopefully it will be bolted back into the car in about 2 weeks.

Diff housing pulled out of the car:

Just opened it up and pulled the bearing caps to looked for the c clip for the axles. Only to learn the LSD is like the front axles, They have a snap ring so they just "pop" in. So with a little fineness with a hammer we got the axle ends out:

is the Cusco diff a 1 way, 1.5 way or 2 way?

You'll love it compared to the Torsen. The way it grabs & puts the power down is a real treat.

1.5 way is the easiest to drive with. we have one on the MR2.
on the Alltrac we have the TRD 2 way which i love as everyone here well knows :twisted:
