Once every five years right??? :rolleyes:

Sorry, I just don't buy into the notion they are failing because they're missing a little grease. I drive my truck 800+ miles a month just for work on top of personal miles. I change the oil every 4500 miles. I grease everything that needs it. I rotate the tires. I change the fluids when needed. I also grease it every time I go off-road before and after. It works out just about every month it gets grease. I'm now on my 4th set waiting for the 5th that I paid $54 for. I'm on my third idler arm. This goes way beyond grease.
