Good value
Fitment was exact. I hesitated because it was inexpensive, but it has been functioning well so far.

Arrived damaged
The unit came crushed at the rear and pushed into the bearing; the belt area looked melted. Unusable as received.

Silent and smooth
Installed quickly and the belt squeal stopped right away. Spins evenly, no wobble, bearings feel solid and engine noise dropped noticeably.

Works but low quality
It functions, however there are quality concerns that make me recommend looking for alternatives.

Stopped the squeal
Eliminated the high-pitched squeal on my FJ Cruiser. This is the upper idler; the lower two are similar to each other but different from this one.

So far, so good
No issues at the moment; the part seems well made. Time will tell. If replacing the tensioner pulley, add washers during installation.

Fits ES350 quietly
Matched my Lexus ES350 and turns without noise.

Too much play
Feels cheaply made with noticeable side-to-side play in the pulley.
