Hello
Today I wanted to change my new pinion 3.78.
the old is a 4.11 Pinion.
now the stock not fit.
the inside diameter of the bearing is too large.
Does anyone know exactly what I need to order for storage (which I have everything completely)

nice would be the item numbers of Macs

thank you

Some pics so we can identify what parts you got to start with and what new ones you got.
If its only the wrong bearings you got or is the ring and pinion different ?
A parts and a shopmanual aint a to bad thing

Might also help to provide the year of rear end you are working on.

i ned this one

The first one you have looks like something out of a quickchange rear has the shaft cut down for a supportbearing ??

deuce lover · 10-24-2015, 01:39 PM

Looks like the pinion has been machined down to take the 33-34 bearing set .Also as flatheadmurre mentioned the end for the driveshaft has been machined for possibly a quickchange setup.You will have to find another R & P set as you should not mix pinions with ring gears.

Also, that pinion gear in your second picture has six splines. Most likely, your '36 driveshaft, if stock, would have 10 splines on its pinion end, and you would need a 10 spline pinion.
