Hi just trying to see if there are any other AC owners out there who have this many problems with their wheel bearings? This bike belongs to a friend of mine it's a 2003 AC 400 4x4 (independent rear) The bike has only 1100 miles on it and he has replaced the front bearings 3 times and the rears twice. Am i wrong or does that seem a little much?!?!? Reason i'm asking is i'm considering buying a two seater Cat but if i'm going to be having problems like that i'd rather buy another brand!

 

I have to replace mine twice and one front three times I do alot of water (up to the seat sometimes)and mud and then I pressure wash it, that hard on bearing. I found that if I pop the black seal on the bearing and pack it with good grease then replace the seal before I install the bearings that they will last longer .I have 2600+ miles on mine.

 

Yes it is excessive. As Bobmack mentioned water and pressure hoses can raise the dickens with them. I repack mine each year (with new seals) but never had to replace one. I have an 03 with over 3,000 miles on it.

 

I have almost 9000 miles and have the original bearings. I would lean toward excessive unless you ride it submerged in water a whole bunch AND have sized tires. This combination put a lot of stress on the drive train, especially the bearings.

I will add that I have one wheel on my 400 that is a little loose and I will probably put new bearings in this winter but I will have nearly 10k miles by then.
