All valid concerns.  He's a retired machinist and knows how to measure accurately and understands the tolerances involved.  It would take replacing the 2 yokes for a different U-Joint, not just one, which is obviously more expensive.
	
		
			
		
		
	
				
			Yeah, a quick look at yokes shows the cheapest at about 34 bucks. However, I saw a complete driveline from VEVOR, complete with clutch, for $109.99. Link: VEVOR PTO Shaft, 1-3/8" PTO Drive Shaft, 6 Spline Both Ends PTO Driveline Shaft, Series 4 Tractor PTO Shaft, 31.5"-41" Brush Hog PTO Shaft, Yellow PTO Shaft w/Slip Clutch for Bush Hog/Finish Mower | VEVOR USAll valid concerns.

				I didn't either, I was just curious about yoke prices. Being retired myself I tend to be frugal.I had no idea a whole driveshaft was that cheap.
