Frontier 580 Bearing extensions
I just bought a slightly used 2010 Frontier 580 and i want to install bearing extensions part #810-112. Anyone done this - is it straight forward or do you have to totally disassemble the existing bearings to get the extension on?
I just checked the part I can't tell you if it can be done or not but, i have a bigfoot and have thought of using those same extensions on the rear axels. Looks like you have to cut the tub skid plate, easy. Then you have to drill the mounting holes which I think i would temporarily install the bearing flange bolts to properly locate the extension to the body/ frame. I was thinking of cutting off the angular area and making the perimeter rectangular, it's also one less hole to drill. I wasn't going to upgrade to HD bearings as I just replaced all mine about 20 hours ago. Seems easy enough and probably overkill but I like the idea of the outer bearing being as close to the hub as possible. Should all work on my machine would have to look at your model to see but i would think it would work. Does your machine have the front bearing extensions? I thought that was standard after the vanguard models, but I'm no expert.
With the 2010 model this is an option so no drilling etc. The Frontier 640 model comes with them standard. I talked to two Argo mechanics. One said it would strengthen the axles to prevent bending under heavy load etc. He advise it even though I have no intention of installing a track. The other said it would be a waste unless I was doing some ploughing? and/or installing a track. He said you have to remove the wheels and the existing cover then the bearings actually get moved 2-3 inches further out on the axle. As I am using it for hunting - mainly trails etc, I don't think i will bother unless someone has some experience here.
Do it for the piece of mind. If your driving and the front end falls down in a hole (this does happen) the impact can bend an axel. I would defiantly do it if you have the money... and tracking it some day is probably a good idea
