Strange noise
« on: October 02, 2016, 01:32:27 PM »
Ok, I'll try at some point to get a video but in other attempts the sound doesn't come out clear on the video.  So I'll do my best in a verbal description.

Noticed it when running high gear before, now noticing it in low.
When going down bumpy or rocky hill hearing a "clunking" noise and can feel it in the floor under your feet.  As if the feeling or sound of a loose transmission in say a jeep. Feel it in the floor boards as you would if a small rock hits the skid plate.
Doesn't do it when climbing up a hill or when on flat surfaces or when the engine is doing any kind of pull. Even worse if I let it just coast down a bumpy hill. 

Tried to replicate it with engine off and rocking it forward and back but nothing, nothing seems "loose".  Think I'm going to pull the skid plate and get a closer look.
Or do I have to pull the interior plastic out and check ?

Sounds like a front driveline problem. Maybe a bad carrier bearing or U-joint or like mine, very loose spline....except mine does it's thing which is like a whipping driveline under load, not costing. Either way is tough enough..IMO to get to it.

I get the clunking from the rear shaft. Mine is pretty sloppy.

Sounds more rear, but feeling it in the floor concerns me.

Check the motor mounts...CFM is known for loose bolts...and broken mounting tabs.
