EZ Lube Spindles by Courtsara

If you have a medium duty truck with a 4WD system, you have likely encountered problems with lubrication in the spindle bushing/axle and packing the bearings of the hub area.   Even the easiest axles require removal of the brake drum and tire. Some axles have a fitting on the end of the hub, but you have to risk cutting the seal slipping a screwdriver (or something like it) through the axle seal and pump grease until it purges out past the seal. The most convenient have a grease fitting inside the brake drum.  None of the major manufacturers can pack the hub bearings other than the old fashioned way which causes truck down time and is labor intense.  Lack of serviceability can result in costly repairs, often costing $3500 to $7200 in parts alone, plus labor and downtime.

There had to be a better way, and we found it.

Courtsara has customized major manufacturer spindles (patented in the U.S. and patent-pending in Canada) that saves countless hours of work by allowing your mechanics to pack the hub bearings and grease the axle bushing in a matter of minutes. Our EZ Lube Spindles can be done every time you service the truck.  The benefits from such a customization are immediately apparent to anyone who has ever done this work procedure the old way in the past.  (Update) We are manufacturing our own spindles starting with the models listed on the quote page.  These spindles are 100% American Made and built to exceed OEM specs.  We know that with our patented greasing system and higher quality bushing we will be delivering a product that will give you years of trouble free service.  This is going to be the industry standard!!  Until we start manufacturing all brands we will still be customizing and taking cores of those brands.

Reduces Service Downtime

Downtime is a killer for your bottom line and your profit margin. In industries where margins are slim to begin with,  you require all your employees and machines to be running at peak efficiency throughout the shift.   Having a truck down for days in order to grease it, not only brings that truck out of use for another team, but it can also eat up a garage bay in case something major goes wrong with another truck. By getting the trucks in and out of the garage with a regular service instead of major break downs, You will get more truck availability and not miss a beat.  


Our EZ Lube Spindles increase the serviceability of a job like this, and by reducing the amount of technical knowledge needed for it, you can reduce the number of mechanics needed to work on a truck at any one time.  Mechanics now simply need to locate the grease fitting, and pump the grease into the spindle assembly until the grease begins to come out of the pressure relief fitting.  A job that normally takes 16 hours the old way is now done in minutes and you can do it every time you service the engine oil.  Its that easy!  No more wrenches, or specific tools necessary, just a mechanic and a grease gun, and this part of your service is done in a few minutes.


No more removing 200 pound tires or 90 pound brake drums. Doing lots of work with your hands in confined spaces with metal is a situation in which injuries are bound to happen.  Back, hand and foot injuries are a workman compensation nightmare.  By removing the need to get into the guts of each spindle and axle to perform routine maintenance, you're removing nearly all the risk to bodily injury from your mechanics. Your mechanics won't have to be in solvent tanks and handling toxic sprays.  This is a manager's dream come true, to reduce the cost, time, and danger associated with this maintenance.
