New 914 rear wheel bearing, No to very little grease from manufacture Options

[Luke M]

So, I just purchased a set of New FAG wheel bearing (made in Germany) so I can install a set of the later (74-89) 911 rear hubs on my 914 control arms.
I saw a few you tube videos about how the bearings for the Boxster where being shipped with little to no grease in them. I figured before I install them to check the grease. Well sure enough one side had little grease and the other side had very little to no grease on the bearings. I should've taken a few pics but didn't have my phone handy. I still have another new bearing to inspect so I'll take pics of that one. I'm sure it will be the same way. Now to go pick up some grease and repack them.


So if anyone of you out there plan on replacing your rear bearing I would inspect them.

Here's a handy video which shows how to do this.

The other thing that drastically affects durability is pre load on the bearing. 914s rear is a double row ball bearing with a split inner race. The torque you put on the hub to CV stub is what creates Pre Load.

Over torqueing that joint will lead to too much bearing preload. Let’s be honest how many of us have put a little “extra” torque on that torque wrench just for good measure - cause we all know tighter is better. I’ve done it in my younger years.


Likewise I trust that it is common knowledge that rolling a 914 without that CV stub installed will lead to bearing failure in very low miles.

Lots of other uncontrolled variables in all these intrawebz / YouTube discussions could be leading to perceived grease failures.
