Product review (2 stars): Parts are Aftermarket Not Genuine OEM as Advertised
I carefully looked to make sure these parts were genuine Whirlpool parts but they were not.  Genuine Whirlpool parts come in an FSP bag with instructions.  Even though the write up said there were instructions, none were supplied and it was not a FSP bag.  The new drum support wheels did not rotate as smoothly as the old ones on the shafts and one has excess rubber at the drum contact point.  The plastic retaining clips were hard and unpliable and thus would not fit on the shaft, had to use my old ones.  The steel shaft support retainer clip was too large too fit, again, I used my old one instead.  The belt was a Goodyear and the idler roller seemed to work fine.  Now instead of the scraping noise by dryer was making, it has thump.  Hoping it wears in and stops thumping, may have to put the old wheels back in again and try that.  Amazon was great about offering an adjustment to me but I would rather have gotten genuine parts to start with.  At least the dryer is working again but bad experience with this supplier's product.
