Hi All -

Going back over my 3 speed TC while I have it out. Checking preload. I have braking drum and speedometer housing off the back as seen below. I have in-and-out free play on the output shaft. Is this normal? Is seems like it should be tighter, but I did not know in the shims eliminate the issue.

The output shaft preload is set by shims between the speedo housing and the rear bearing. Are you checking it without the speedo housing installed? It's meaningless without the speedo housing in place.

No, I understand that everything needs to be in place to measure preload.

Looking through the transfer case top cover, the shaft/gear assembly and parts are correct (I thought I might have forgot a washer). Maybe I just need to further drive in my rear bearing cup? There is a gap between the rear bearing and the cup that allows the free play. I thought the speedo housing with shims would further press the cup in. FSM calls for a SST to install that rear cup. I know for sure I did not do that in the TC rebuild assembly.

I don't know of any SST to seat the outer race of the rear bearing. That's the function of the speedo housing and shims.

X2. Install Speedo housing. Measure preload. Disassemble and install/remove shims as necessary. Rinse. Wash. Repeat.
