I have an 07 rancher that squeaks intermittently from the front differential?.(not exactly sure where it is coming from) The squeak only happens when in 2WD, and does not always happen. It can be quiet for several miles, then start squeaking. It only happens when the bike is moving. Any ideas?

 

Welcome aboard! Can you grap front rack push up and down on atv? and does it squeak then?

 

I can shake, push, bounce the ATV while it is stopped and not get it to squeak. When the bike is moving in 2WD, as soon as the 2WD - 4WD select lever is moved to 4WD the intermittent squeak goes away. Put it back in 2WD drive, and squeak comes back. With the bike off, moving the lever from 2 to 4 WD, I can occasionally get a squeak. I took the plastic cover off covering the cable end where drive select takes place, everything looked OK under cover.

 

Okay lets get some history of atv first! Did you buy atv new? Has atv always done this? Have you added anything to atv lately? Did you buy used?

 

I had the exact same problem on the same year Rancher. I took to the dealer and the fix is real simple. Spray WD40 on the outer and inner CV joint boots an the problem will go away for a wile and the return, just spray again. According to the dealer this is a common problem and relates to the rubber formula that was used for the manufacturing of the CV boots.

ATV purchased new. Has 500 miles on it. Started doing it at 300 miles. When it started it was very intermittent, now it is almost all the time. Nothing has been added to the bike.

 

I have heard that spraying WD40 on rubber is not good. Silicone spray is best to use.
