[Chuckie3]

P-5 started making noise going slowly down hill when using the brakes,but it’s not a brake sounds like gear noise.shifts fine otherwise no problem any ideas.

Axel or u have crap (mud) in the drivetrain.

What's the noise sounding like?

 

[trigger]

Not the normal chain in a can sound?

Sounds like gears grinding but shifts fine runs great except for slow down hill on brakes.when I go down hill slow with out brake it’s fine 🤷‍♂️

What year, how many miles, muddy or sandy riding environment? Maybe time to inspect the brake pads.

I agree with checking your break pads. I had tiny rock get caught in my rear breaks that was making noise when breaking. It didn't come out till I changed the pads. After that it went away.

mine does that from time to time going down really steep hills when using the brakes. I replaced rear pads and put synthetic gear oil in front and back still will occasionally do it on really steep hills. I just quit worrying about it as nothing seems to be wrong with the machine. I think it is just the design of the brake on the rear drive shaft vs on each rear wheel causing the noise. Only on really steep downhill decents.

Rotor bolts ?

I’m going to take rear brakes off clean them make sure everything is tight and see what happens. Thanks for your guys input

I've "heard" noises that may be similar to what you're saying. Can't remember if it was going down hill or not. I haven't been out west since January. But I do remember I kept riding and Pockets kept rolling on. Hopefully just a rock in the brake pads.

Compare it with another Pioneer. I expect they will both make the same banging noise. I think it's the rear wheels slipping then catching allowing the ring and pinion gear to make the banging noise.

Mine has done the same. Usually after it has been sitting undriven for a while.
Seems to go away with use.
