3/S 6 Speed 4th Gear Check BallChris Behnken
If you decide to do a synchro swap on your 6 speed AWD transmission there is a very important item to be aware of.
Above 4th gear is a ball bearing that holds the thrust washer from rotating. If you try to press all the gears off in one shot you will crack the bearing sleeve and damage the input shaft.
The key is to place a sharp bearing splitter under the 4th gear engagement teeth and press 4th gear off once you have 5/6 out of the way.
