Tensioner Pulley
The bottom nut
The pulley to the left
Geez, that looks bad no?
Yesterday, while driving home, steering got tight, battery light came on, thankfully was able to drive home, (which wasn't VERY far). Got home, a little smoke from the engine, opened hood, immediately found serpentine belt (replaced less than a year ago) broken. Upon further inspection found tensioner pulley a little snug. Today, took it off and it appears the bearings are bad. Now, my question is, do I have to replace the entire thing or just the pulley? I'm having a hard time getting that nut off and that's also the nut you use to release tension to change the belt. (Sorry for the slightly blurry pictures). It is the 1994 S10 Blazer Tahoe, 4.3L V6 OHV12V with the "W" in the VIN.

Thanks.
They just don't sell the whole thing around me, just the pulley. Would have to order one online. (Live in the PA mountains/boondocks). Then I wouldn't get it until next week, fish out of water until then. Seems like I may not have a choice.

Hmmmmm, local bone yard have one you could pull and use in the meantime? Otherwise, soak that puppy in your favorite Pb blaster, liquid wrench, ATF/acetone penetrate of choice and keep trying to remove the pulley. I’d still order a whole new one though...
