x17z wheel bearings

I decided to take my wheels off my x17z and buy some new tires. After removing the wheels I found that there is a grease fitting behind the center cap. Just wondered how much grease should I pump into the fitting to lube the hub. Is there something to tell you when it is full?

There is a post called "ez-lube" started this spring. There is a lot of info about luring the axles. You do need to be careful as you can blow past the rear seal and make a mess of the brakes if you pump it in to fast.

Basically pump in the new lube slowly and the old comes out near the zerk. When it comes out clean stop and clean up the old grease.

In addition, spin the wheel while pumping in the grease.

The video from Dexter on how to lube them. Dexter also recommends certain grease so don't use anything you have laying around. I suspect they just pack the bearing so the cavity between them will be dry and lubing them the first time will take a lot of grease.

OH YEAH!!!!

Then you have to pump a whole lot in to displace ALL of the old grease at each freshening.

While spinning the wheel, check for runout and adjust the spindle nut as needed.

Is there a way to know if you have the EZ type or not? Is that little round cap in the center of the wheel just pop off with a screw driver?

The EZ-Lube have a rubber cap in the center of a more cylindrical dust cover.

If you have a domed, all-metal dust cover, then you have the traditional setup that requires disassembly in order to repack the bearings.

-----------

The way I was taught to remove the dust cover was with a rubber mallet. Strike lightly downwards and outwards (pull as you tap) while rotating the wheel. This nudges the cap out of the drum.

During re-assembly, the mallet is used to drive the cap back into place directly.

I had to remove the wheel to remove the center cap to get at the fitting to grease the bearing. The center cap is put on from the back of the rim.
