Got a question about something that has popped up on our RTV. Here in Texas it is still in the 90's and I have noticed when we are out taking care of things on the place that when we stop somewhere for even a few minutes and go to take off I hear what sounds like three chirps coming for the HST area. The RTV has to be hot from driving for a while and it is in the middle of the heat of the day. I found I can start off in High gear and I do not hear it but we use low 90% of the time just because of the slower speed in the woods.

The HST fluid level is good and the fluid and filters were changed about 100 hrs. ago. Until the RTV gets good and hot we never hear the noise. Anyone have any input if this might be an issue or nothing to worry about. Other than this noise everything seems to be running as normal. RTV has 3600 miles and about 600 hrs. on it.
 
I've never heard anything similar to that. We had a very hot summer here and I worked the RTV just about daily. But I rarely use Low.

Check the oil level in the gearbox? Has the gearbox oil been changed? Check the driveshaft to the front diff and check the oil level in both diff and the outboard hubs.
 
By the Gearbox are referring to the HST drive unit? All fluids and filters under the unit were changed about 100 hrs ago and all levels are good. I guess I will see how it goes as the temps start cooling down outside.
 
Is that the reservoir located under the passenger seat? If so it was changed at the same time as the other fluids and it is at the correct level. If that is not it then I have no clue.
 
Check the rear muffler support hanger, they are known to fracture and produce a squeaky sound by the 2 metals rubbing together at the fracture.
 
Just checked it before I put it up for the night and it was solid as a rock. I am just going to see if the sound goes away when it gets cold here and if so I will figure it is a Summer thing.
 
The gearbox is its own reservoir. There are free downloads for manuals in the sticky section. Or running until failure is always an option
