I think my semi-Asperger’s brain might have figured out why my XForce surface cleaner bar sounds like a steam train and vibrates.
The guys at Southside suggested I change the cartridge, no effect. Changed with new nozzles twice, nothing. I took the nozzles out again tonight and one socket looked a little off.
Three measured the same 80 degrees, one is at 72 degrees. I messaged CS at WW, waiting to hear back if I can turn it back a little myself as it’s staked in place.

That’s interesting, how did you measure that? I have a slight vibration but doesn’t seem any different than the original bar. Good to know, I’ll measure mine too, once you tell me how, 
I started with an old school protractor then verified with my ‘level’ app on my phone which shows 8 degrees difference. I’ve been chasing this chuffing/vibration ever since I bought it. Oh and I still had that long shooter nozzle I never use for a better measurement.
Looks like the problem is a ratchet on one end. 
Very interested to see if this is the issue. My OCD has had me curious how much a slight variation in nozzle alignment could cause.
I talked with the WW rep and he mentioned it can be off a few degrees. I put it in a vise and tweaked it back to the same angle as the others (10 degrees) so I’ll test it out tomorrow
I got a chance to try it today and after dealing with a clogged nozzle, it is SMOOTH now. Not a hint of vibration, works great. I highly recommend checking the angles as it’s what causes that ‘chuffing’ like a locomotive.
It does take a lot of force to unscrew the ends, fair warning
Thanks Chris for the info, good to know. Glad you got it figured out and it’s running smooth.
