I have a Dyson DC171
whose beater bar/brush roller stopped turning today. I have done all the basic checks and gone through about 20 different websites/videos to see what I'm missing. The roller is free of hair/lint/debris, the gear is clean (to my surprise), the belt shows no signs of wear/cracking and engages on the gear without problem, etc.
I now suspect that the problem may be the roller bearing/s, and am preparing to order a new roller, but before I do I wanted to see if any of you can perhaps answer the one question none of the other sites have mentioned.
My roller has two "endcaps" which are not removable so far as I can tell. At one of these caps, the one more distant from the belt, the roller turns smoothly and with very little resistance. At the other, the one closer to the belt, the roller turns, but is pretty stiff. Rating them on a scale of 1 (spins like a pinwheel in a breeze) to 10 (won't budge), I'd rate the distant end at a 3 and the nearer end at a 7.
Is this normal, or should the resistances be more evenly matched? I hate to buy a new roller only to find out that's normal movement for this part, and that the problem is actually with the motor or wiring or something. (It should be noted, however, that there was no "electrical smell" or similar when the roller stopped - just a few weeks of a knocking sound which I had attributed to a coin I accidentally vacuumed up, then today a high-pitched squeal followed by failure of the roller to turn.)
Any information will be appreciated - and I also wanted to thank the moderators/admins for requiring email confirmation before activating new accounts. My inbox is currently filled with spam from websites that will just take any email address and stick it on their mailing list, so I genuinely appreciate sites that require a registrant to prove the email account is actually their own.
Thanks in advance,

I really hope the answer is not
