Is There a Risk of Adding Too Much Grease to an EZ-Lube Spindle
Question:
Thank you Jon for that response! I read the page, and it was helpful. Just so then I'm clear, if my TT is constructed with EZ Lube axle and has no Bearing Protector on it, that means yes I can use the EZ Lube feature with a grease gun with no risk of breaking a seal? And furthermore, which product of Grease would you (etrailer) recommend going forward with a grease gun? Thanks again for your help!

When you are replacing bearings you do want to pack them prior to installing the new ones into your hub. This ensures that the grease actually gets pushed completely into the bearings so that they work properly and don't overheat. You can use a bearing packer like part # PTW1218 or # ALL647646 to accomplish this. The grease zerk fittings on your EZ-Lube spindles you are talking about are more for adding grease between changing out bearings/seals/hubs.
I believe the section of our linked bearing FAQ you are talking about is where we mention pumping grease into the hub when using bearing protectors. We are actually talking about something like the Bearing Buddy Bearing Protectors # BB1980A-SS which put more pressure on the grease to help keep water out of the hub. Since these put pressure on the grease you can experience a blowout as the grease seal will be the weakest section. For EZ-Lube spindles they are designed to allow the grease to seep out around the washer so you can't actually put that pressure on the grease seal. If you just have EZ-Lube spindles then what you initially read is correct. If you have bearing protectors then you do need to be cautious about overfilling your hubs with grease.
