Question:

I have E-Z lube axles. I dont use the E-Z lube grease fitting. Can I run standard caps and service the bearings like tike a traditional axle.

You sure can Cary. There's no space restrictions that will keep you from installing a standard grease cap like item # F001524 on your hubs.

Why don't you want to use the E-Z lube grease fittings?

Jared, I use the easy lube axles for a while and it actually pushed grease out of the wheel seals rather than pushing new grease through the bearings. I'd rather just pull apart my wheel bearings like a traditional style and service them as normal. My concern about using standard caps is I have been told that the EZ lube caps have a microscopic hole that allow the wheel bearing to breathe as they heat up and expand.

@Cary I've heard of that happening before. Typically it's when people use powered grease guns. The microscopic hole is not something I have heard of. The bearings are the same, just different sizes, no matter what type of axle you use.

@JerredH thanks, yeah aside from the spindle being drilled for grease, I can't see any difference in these axles when compared to a traditional style. I'll just run some standard caps because they are cheaper and service my bearings the old-fashioned way. Thanks again for your help.
