Rear End Build Up

May 11, 2010 update on blaze86vic's 1973 Toyota Celica 1973

I rebuilt the rear end of the Celica as I have been having problems with the longevity of gears in this car. I know the rear is rather small, and really not suited to high HP applications, but I’m not the first person to run 180ish hp through a 6.7” Toyota rear. So to rule out any problems with the setup, I decided to redo everything with new parts everywhere. New axle, carrier, and pinion bearings as well as all new seals. New universal joints for the driveshaft and a new center support bearing. To go with this I took a carrier and sanded down most of the rough surface, and powder coated it as well as the pinion flange. I had planned on going with an aluminum spool, but then I got a TRD 2-way LSD. I installed a new set of 3.90 gears that I also sent to Evans Performance to be cryo-rem’d. I also installed a solid pinion spacer to eliminate the need for a crush washer. First part is the differential build, and the second part is the rest of the related rear end rebuild.
