Jeep Grand Cherokee wheel hub

this is the third time i have to replace left front wheel hub is there a problem with the hub or is it spindle

Wait a minute, let me get out my crystal ball so I can see thru the internet…

How about a little more information, Ray? What year? How many miles? Why did you replace the first Hub? Accident? Curb hit? Rock climbing at Moab? Was anything else replaced at the same time or just the hub. Did you replace all the hubs yourself? At the same mechanic? Different mechanics? Help us out here so we can help you.
