Thump, thump, thump mystery noise

I'm VERY familar with the annoying transfer rod cluck and I've fix that. Not the problem.

I'm ordering a new bearing with a new set screw. I'll try that and the belt and see what happens.
 

Defiantly not the transfer rod. Does it on smooth trails.

1705764200635.pngCheck bearing nut, #19 in secondary sheave parts listing. Mine came loose years ago when I had my '08 Apex. Could hear a thumping at slower speeds and actually felt it in the left footwell.
 
That bearing nut is for the jack shaft. I checked and mine is tight. Going to order a new drive shaft bearing and set screw and see what happens with that.
 
Pull the parking brake, caliper , & rotor off and carefully and slowly drive it see if the noise is present.

I had the same clunk clunk noise at slow speed on my 08 vector. Drove me nuts tracking it down. Turned out to be a combination the keyway on rotor & woodruff key had worn enough to create clunk as the rotor turned at slow speed. I sourced a used lower mileage rotor and a new woodruff key. Bam, no clunk.

So, try that. It's a possibility.
